TL;DR:
ATS data goes stale quickly. Job titles change, emails bounce, and companies get acquired.
Enrichment automatically updates records with fresh contact details, current employer, and LinkedIn profile data.
A regularly enriched ATS means you can re-engage past candidates without starting every search from scratch.
The problem with ATS data over time
Every ATS starts out clean. But data decays fast. Studies suggest that up to 30% of professional contact information becomes outdated within a year. People change jobs, get promoted, move cities, change email addresses.
An ATS that looked great two years ago may now be full of records with wrong titles, bounced emails, and outdated company names. When a recruiter goes to search for candidates for a new role, they either work with stale data and get poor results, or they start from scratch on LinkedIn as if the ATS does not exist.
Both outcomes waste time and money. Enrichment addresses the root cause.
What ATS data enrichment actually means
Enrichment is the process of taking existing candidate records in your ATS and updating them with current, accurate data from external sources.
In practice this means:
Updating job titles and current employer based on the latest LinkedIn profile data
Adding or updating email addresses and phone numbers
Flagging records where the person has changed industries or moved location
Adding missing LinkedIn profile URLs to records that only have a name
The result is an ATS that reflects who candidates are today, not who they were when they applied two years ago.
Why it matters for sourcing
An enriched ATS is a genuine sourcing asset. A stale ATS is an obstacle.
When recruiters know that ATS data is accurate and current, they actually use it. They search for past candidates when a new role opens. They re-engage silver medalists. They check who applied to similar roles two years ago before going to LinkedIn.
When ATS data is known to be stale, recruiters skip it entirely and source from scratch every time. This means every hire costs more time and money than it should, and the value of years of recruiting work is wasted.
Enrichment versus integration
Enrichment and ATS integration are related but different. Integration means your sourcing tool connects to your ATS and syncs data between the two systems. Enrichment specifically means that stale records in your ATS are updated with fresh external data.
The best tools do both. TalentRiver integrates natively with ATS systems like Teamtailor and Invenias, and enriches existing records with updated contact details and profile data as part of the workflow. You do not need to run a separate enrichment process or use a separate tool.
How often data should be refreshed
There is no universal answer, but a useful baseline is to enrich records for candidates you are actively considering for outreach. Batch-enriching the entire ATS annually is a good practice for larger organizations.
The more targeted approach is to enrich records in real time as you search. When a recruiter runs a search in TalentRiver, the tool pulls the latest LinkedIn data for relevant candidates automatically. The ATS record is updated as a by-product of normal sourcing work rather than as a separate maintenance task.
The compounding effect of consistent enrichment
Each time you source a role and enrich the relevant candidate records, your ATS becomes more useful for the next hire. Over two or three years of consistent enrichment, the difference between an enriched database and an unenriched one is significant.
Teams that invest in enrichment find that their ATS increasingly covers the candidates they need before they need to source externally. Re-engagement rates improve because contact details are accurate. Time-to-hire drops because warm candidates are reachable.
Key takeaways
ATS data decays at roughly 30% per year. Without enrichment, your database becomes less useful over time, not more.
Enrichment updates job titles, contact details, and employer data in existing records to reflect the candidate's current situation.
An enriched ATS is a sourcing asset. A stale one is an obstacle that recruiters learn to skip.
The best enrichment happens as a by-product of normal sourcing workflows, not as a separate maintenance task.
FAQ
How does data enrichment differ from scraping?
Scraping typically refers to bulk extraction of data from public sources without consent or legitimate API access. Enrichment, as implemented in tools like TalentRiver, uses authorized data sources and updates records within the bounds of GDPR and equivalent privacy regulations.
Is ATS enrichment GDPR compliant?
It can be, depending on how it is implemented. The key questions are the legal basis for processing the data, whether the data source is legitimate, and whether candidates have appropriate notice. Tools designed for professional recruiting contexts are typically built with GDPR compliance in mind.
Does enrichment overwrite existing data?
Well-designed enrichment tools add missing data and flag updated information rather than blindly overwriting existing records. A record where a recruiter has added a manual note should not be overwritten by an automatic enrichment update.
How much of our ATS data is likely outdated?
For most organizations, a significant portion. If your ATS contains records older than 18 months, it is reasonable to assume that 20 to 40% of those records have at least one outdated field. The older the record, the higher the proportion of stale data.
What is the ROI of ATS enrichment?
The ROI is primarily in reduced sourcing time and improved re-engagement rates. If enrichment allows you to successfully re-engage even a small number of past candidates per year instead of sourcing cold, the time saved is significant. At scale, it compounds into a meaningfully lower cost-per-hire.
