Data enrichment drives discoverability and bookings. Data that is not searchable is of no use and leads to lost bookings. Enriched, structured data gives both large and small OTAs a strong competitive advantage.

A traveler searching for pet-friendly accommodation enters multiple filters on your OTA platform but finds no relevant results. Within seconds, the traveler moves to another portal where the search instantly returns accurate listings, and the booking is completed.

Large OTAs like Booking.com and Airbnb invest heavily in structured listing data, enriched filters, reviews, and searchable amenities to improve booking conversions.

The loss did not happen because of pricing or user experience. It happened because your marketplace data was incomplete. Your portal did not have enough data to support the search. Leveraging travel data enrichment services helps OTAs improve listing accuracy and search relevance.

For OTAs and travel marketplaces, poor data enrichment directly impacts search relevance, traveler trust, booking conversions, and revenue. Missing amenities, incomplete descriptions, outdated availability, inconsistent property attributes, and weak destination metadata make listings harder to discover and compare.

With the global online travel agency market expected to grow from USD 269.8 billion in 2025 to USD 533.7 billion in 2034, at a CAGR of 7.9%, data becomes mandatory for your success. Travel marketplace data enrichment is the need of every travel portal. Yet many travel marketplaces struggle with OTA data enrichment.

Travelers today search, filter, compare, and decide within seconds. If your data cannot support those decisions, bookings shift to competitors. This article discusses five practical data enrichment strategies that help OTAs and travel marketplaces improve discoverability, traveler experience, and booking conversions.

Today travellers don’t book randomly. They search and filter to make the booking decision and for that, the data must be enriched and accurate. Any missing information shifts the traveller to the next platform.

Data improves search relevance and discoverability, directly improving the conversion rates. Well-enriched data supports accurate filtering and comparisons, building customer trust. Here are some of the benefits of data enrichment for travel marketplaces –

A leading travel advertiser achieved a 210% improvement in marketing productivity and increased average order value by 5% by enriching CRM records with behavioural and visitor-intent data.

Key Data Every Travel Marketplace Needs

Travellers look for information on price, location, reviews, pictures, amenities, and any data that is clear and comparable that can be filtered. The right data reduces uncertainty and speeds up booking decisions.

Property and accommodation data

This covers every single detail about the hotel that will help a traveller understand if the hotel fits their requirement. Basic data like location, hotel name, room types, availability, bed size and other such details must be listed accurately.

Apart from these other basic amenities like pool, Wi-Fi, room rates, seasonal pricing, photos, videos and tours must also be a part of the data listed on your platform. Often, many take a decision based on the reviews and ratings and look for them to make the final call.

Platforms like Airbnb rely heavily on detailed property descriptions, reviews, amenity tagging, and visual content to help travellers evaluate stays quickly.

And lastly, the most important, the policies, check-in/out, cancellation, refund rules and any other such information are important for anybody to select your hotel. Ensure that each field is machine -readable and easily accessible.

Transport and logistics data

This covers any information that is needed to plan travel, like how one reaches the hotel, how they commute in the city and how well the hotel is connected to airports or railway stations.

It includes connectivity details, transfer options, local transport, logistic support like parking availability, valet service and other such requirements. This data supports easy navigation and directly impacts booking decisions. This data is often missing on most platforms and requires enrichment from secondary sources.

Destination and cultural data

This includes seasonal activities, local events, festivals, heritage sites and any such activities or locations that would interest a tourist. Often, a location is selected based on the cultural activities around the city and locations for sightseeing.

This data inspires a tourist to visit the place, explaining to them what they will experience beyond their stay. It creates an appeal for the tourist to visit the place. Most travellers search for this, and often this is found missing in many travel portals.

This needs urgent attention and must be updated with high accuracy and appeal. Some even go a step further and talk about safety issues while roaming the city and how safe it is for women, especially solo travellers.

Pricing and rate intelligence

These are extremely important to be listed clearly with high accuracy, which, of course, most of the portals do. But they don’t go beyond rack rates, while a traveller needs to compare the rates.

The pricing data must include competitor rates, seasonal rate curves, early bird discounts, last-minute deal flags and any such information that hits the pricing and pocket of the traveller. There should not be any hidden pricing, and it should not take the traveller by surprise.

If your hotel has any loyalty program or any package, mention them clearly. Any small print conditions can spoil the reputation of your hotel.

Review and user-generated content (UGC)

These play an important role in building trust, credibility and influence on booking decisions. It is the real feedback shared by past travellers and helps finalise the booking. Platforms like Tripadvisor built their entire ecosystem around traveller reviews and user-generated content that influence booking decisions.

Include reviews and ratings on your services and the experience of your past guests. Go into detail and add reviews on cleanliness, staff behaviour, location accuracy and anything that made your guests happy. This will reduce decision anxiety and strongly influence booking.

And always structure and tag review data into specific, searchable attributes instead of leaving them as raw text. Tag them by theme, sentiments or filterable insights.

Bad data costs bookings

Now that we have discussed the kind of data you must have on your travel portal, just having the data is not enough. In fact, most of the OTAs already have the data, but if the data quality is not good, it may not get you the results you expect. Here are 4 specific issues that have a direct impact on conversion.

Fragmented supplier data

Any inconsistency in the data can lead to wrong search results and then missed bookings. For example, if you want to mention ‘swimming pool’ as an amenity, then you must ensure that it is stated in the same way across different data sources.

If different sources mention the same amenity in different ways, as some call it ‘swimming pool’ while others call it ‘outdoor pool’, the system may get confused. Though humans would understand the machines may not, and for a filter for ‘pool’, the property might not show up at all. Without normalisation and standardisation, that property fails to match filtered searches.

Untagged visual assets

You may have the best pictures on your platform, but what use is it if they don’t show up in search results? Images uploaded without tags cannot be traced by search algorithms and cannot support conversions.

High-quality visuals increase engagement significantly, and most travellers want to see property visuals before booking. Ensure that you tag your photos so that the machine understands and shows up in search filters.

Stale enrichment cycles

Most of the travel data changes very fast, like flight schedules, price shifts, closed for renovation and other such things that make data stale. The data needs to be updated regularly, and if possible, real-time updates are the best.

Portals running on monthly or quarterly enrichment cycles often end up with wrong data, and the traveller loses trust in the portal. Imagine a person making a booking with the wrong data, only to realise later that the amenities he filtered were not available.

Thin traveler profiles

To personalise results on your portal, it is important to capture the traveller profile, which most of the OTAs miss. One needs to capture behaviour like past searches, budget, preferred filters, or trip type to customise the offerings.

After all, you don’t want a honeymoon couple and a person looking to book a corporate event to see the same options.

All these issues can be fixed if you follow a structured enrichment approach.

All four issues we just discussed can be fixed with a structured enrichment process. Here we list 5 travel portal data enrichment practices that will improve booking.

Data Enrichment Moves That Drive Bookings

Make local events and cultural data structured and searchable

The local events and cultural data are not just for engagement. The real purpose is to get bookings and not to just inspire the travellers. If your data stays, there as static content, it will be of no use to the travellers. The data must be tagged properly so that it is easily filterable and drives discovery and finally booking.

Every detail about the event must be presented in a structured manner. It should be divided into categories like event type, date, duration, location and even audience type. It must also clarify whether it is for family, nightlife or a cultural event.

For example, the Pushkar fair could be tagged as seasonal, Rajasthan or November, while the Goa carnival is tagged as nightlife and near beaches. This helps travellers plan trips better. They could filter hotels near the event or even decide on the time to visit the location.

Such kind of information and tagging improve discoverability and help plan the travel. To improve the engagement further, one could even personalise the page by matching profiles with interests. A person more for adventure could be shown more trekking events, while a couple could be shown cultural events.

Apply structured metadata standards to all image and video assets

You may have hundreds of photos and videos on your portal, but if they are not tagged it may not be searchable. It will just stay there in your OTA and will never appear in any filter or search.

Without structured metadata, the platforms become difficult to navigate and are abandoned fast. It leads to poor search visibility, wrong matches, lower engagement and lost bookings. You need to take steps to ensure your visuals are searchable.

So, what do you need to do? Begin by deciding what information every visual should carry. Every image or video should be labelled clearly with property ID, image type, amenity, location and keywords, to name a few. Any tag that helps the user filter easily.

Be consistent in naming and categories and use one format. A swimming pool should not be defined any other way. Always use ‘swimming pool’ and not ‘pool’, ‘outdoor pool’ or in any other way. It is always a good idea to add metadata while uploading images and videos with dropdowns or predefined fields instead of free text. This ensures consistency and quick tagging.

And most important for large-scale tagging use is AI-enabled automation. AI can detect amenities from images, while NLP helps extract tags from descriptions and reviews. If the supplier API is used, always normalise data so that filters work efficiently. Using metadata the right way drives bookings.

And lastly, data needs constant enrichment, so keep adding missing tags, update info and keep improving based on user behaviour.

Enrich pricing records beyond rack rates to power comparison and personalisation

Just listing price may not work even if the price is attractive unless the traveller can compare the rates across different hotels. It is not only the price they are looking at; they need value for money.

Once travellers complete their research across multiple sites and compare prices, they proceed to make a booking. Bookings do not always happen at the cheapest location, but where pricing is easy to understand.

OTAs such as Expedia Group and Booking.com continuously optimise pricing visibility, loyalty discounts, and comparison features to improve conversions.

That happens when pricing data is enriched with contextual information. Enrich the pricing data by adding competitor benchmarks where the price compares with similar properties. Add seasonal trends, deals, loyalty pricing and any other point that adds more to the pricing than just a number.

This helps users compare and make an informed decision. It builds trust, transparency reducing any kind of ambiguity or confusion. This further helps in customisation; for example, for a price-sensitive customer, deals and discounts can be made more visible, while a premium customer can see value-added packages.

Extract and structure travel trend signals from social and behavioural data sources

Social listening is very important to capture trends that tell you what travellers are likely to explore next. This data must be captured from multiple sources scattered all over, like travel blogs, social media, reviews or even user behaviour on your platform.

You need to get into the skin of travellers to understand what is getting popular with different age groups, like it could be adventure for the young crowd or wellness retreats for older ones. The traveller’s concerns must be noted, such as safety, hygiene or overcrowding. You need to segment people based on solo travellers, family people or digital nomads.

The data gathered is too raw and noisy to be structured by categorising, tagging or linking to destinations. For example, Lisbon could be tagged with nightlife, while Bali with wellness retreat. Proper and structured tagging can drive real and quick decisions.

Now, once you have structured data in place, building strategies gets simpler and more effective. You know exactly what experiences or destinations are in demand, so you promote them. Personalisation also gets easy as you match users with relevant experiences.

Once strategically presented, the data makes your platform dynamic, open and trendy, driving bookings.

Use data tagging to build traveller segmentation into the supply-side record structure

So far, we have improved our data, but the data must connect to the right traveller to get the full benefits. We need to make the data work.

They can’t work in isolation. We don’t want the same listing to be visible to all; it needs to be customised based on the data that we have gathered. With the right segmentation, the platform understands the intent and the results are tailored automatically, so that browsing converts to bookings.

Even AI needs structured data to work upon. Without segmentation, even advanced AI produces weak results. Therefore, for relevant searches, faster decisions and a better experience, you need structured and well-tagged data that translates into revenue. You need to assign segment tags like the luxury segment or the budget segment.

High-priced amenities should be targeted to the luxury segment, while basic amenities could target the budget segment. And these tags are not guesswork; they are based on data that is gathered and analysed.

The five practices that we discussed apply across all marketplaces. But based on focus and requirement, the approach may vary. Here’s how to approach different platform types.

Enrichment priority Budget / price-comparison OTA Luxury & boutique OTA B2B / corporate travel platform
Highest priority Dynamic pricing data Visual asset tagging Traveller profile enrichment
Second priority Traveler segmentation Cultural & event data Pricing & policy data
Third priority Review sentiment tagging Review sentiment tagging Real-time availability feeds
Refresh frequency Daily (pricing) Weekly (content) Real-time (availability)
Key quality metric Price accuracy rate Image completeness score Data completeness SLA
Speed impacts bookings

Now we have established the need for data enrichment and what data needs enrichment. But you don’t apply the same enrichment criteria to all data types. Not all data changes at the same speed. Some need real-time updates, while some can be updated at intervals.

It is important to understand both the approaches, real-time updates vs batch enrichment.

Real-time enrichment applies to data that changes very fast, like room availability, flight schedules, pricing or event cancellation. This enrichment happens through API integration with GDS feeds and supplier systems. Here, enrichment happens during the user query, where the system takes live data and adds context instantly.

Batch enrichment applies to data that doesn’t change frequently, like property details, images, reviews, and destination content. Here, enrichment happens in advance, in a structured process. This includes standardising amenities, tagging images, verifying descriptions and other similar processes.

To explain the difference through an example, when tags such as ‘luxury’, sea view’, etc. are used, it is batch enrichment, while ‘high discount of 20%’ is real-time enrichment. Real-time enrichment handles live data and is fast, automated and API-driven, while batch enrichment works on scheduled cycles.

A leading US-based data aggregator in the hospitality sector processes over 17 million records annually. These records are used to power targeted marketing strategies. They implemented a structured data cleansing and enrichment framework.

This included validation, segmentation, and real-time verification. As a result, they achieved consistently high data accuracy. Turnaround cycles also became faster. This enabled better decision-making and stronger outcomes for their clients.

Read the complete hospitality data enrichment case study to understand how structured enrichment improved large-scale travel and hospitality data operations.

Even the best travel marketplace fails if the data behind it is outdated, incomplete, or inconsistent. Maintaining accurate travel data requires continuous monitoring, validation, and updates across every listing and source.

Keep OTA listings accurate and ready.

Travel data enrichment is no longer optional as it directly impacts bookings. Today, the majority of travellers book through OTAs. They look for availability, price, local events, connectivity, safety protocols, flight availability and things like that to decide.

Most of the OTAs understand this and keep enriching the data, but again, the data should be searchable. If the data cannot be filtered or traced, then it is of no use. And if the data is inaccurate, then again, it will lead to wrong search results, ultimately hitting the trust.

The travel data must be standardised, structured, segmented and enriched with pricing and context so that it adds meaning to the person looking to book and supports their booking decision. Enriched data is the foundation for personalisation and AI, and without it, even advanced systems won’t perform well.

Better discoverability drives higher conversions, improving revenue, while without proper structuring and enrichment, the data just sits there and is of no use. The goal is to have data that works.

What is data enrichment in travel marketplaces?

Data enrichment in travel marketplaces involves enriching the data in the platform by adding any missing fields. The process further includes checking for accuracy, verifying and standardising the data. The process covers the entire cycle from tagging images and videos, updating pricing from various supplier APIs into a consistent schema. This helps the data be useful for travellers looking to book.

How does enriched data reduce OTA booking abandonment?

Booking abandonment usually happens due to irrelevant search results that occur if the data is not structured and not tagged. Outdated pricing or missing property details also leave a user frustrated, and he leaves the platform without making a booking.

Data enrichments address all these issues, where the data is easily filterable and searchable. There is complete information and comparative pricing.

What is the difference between data enrichment and data cleansing for OTAs?

Data cleaning corrects the existing data, while data enrichment adds new data from various external sources. Both are needed in parallel.

Data cleansing corrects typos, removes duplicates, formats inconsistencies and checks for invalid field values. Data enrichment adds what is missing: new fields, metadata, behavioural tags, and structured taxonomies that raw supplier data does not provide.

How often should travel portal data be enriched?

Enrichment depends on the kind of data, and you must schedule accordingly. Certain data needs real-time updates like pricing, room availability or event cancellation. On the other hand, reviews, property description, image metadata or amenity taxonomy can be scheduled monthly.

How does travel marketplace data enrichment prepare an OTA for AI-driven travel search?

AI travel assistants like ChatGPT, Google Gemini, and Perplexity now pull data directly from OTAs. They prefer structured, machine-readable data over raw content. To be visible, OTAs need JSON-LD schema markup, Clean and consistent API data, and properly tagged metadata. AI systems only use data they can clearly understand and process.

What data quality metrics should OTAs require from enrichment vendors?

Key data quality metrics for OTAs include field completeness, field accuracy, deduplication rate, and refresh SLA, i.e., time taken to update changed data. The vendor must provide baseline audit results before onboarding and share ongoing performance reports during delivery.

Can smaller OTAs benefit from data enrichment, or is it primarily for large platforms?

Data enrichment matters for all OTAs, but it matters even more for smaller ones. Large platforms can survive poor data because people already trust and return to them, but smaller platforms don’t have that advantage. They rely on good data to compete.
