CONTACT USFrequently Asked Questions
Is DataForSEO Labs the only DataForSEO API useful for keyword research applications?
No. DataForSEO Labs is the API most teams build their core keyword research workflow on, but three other APIs feed into it depending on what you’re building.
- Keyword Data API can give you fresh Google Ads and Bing Ads data at scale when you need large volumes of unmodified source values for keyword metrics.
- DataForSEO Trends API is our in-house alternative to Google Trends, but with higher throughput and a different, more refined, methodology. A well-built keyword research tool typically calls at least two of these in combination with DataForSEO Labs API.
What is the source of data in keyword research endpoints of DataForSEO Labs API?
The keyword research endpoints draw on four data sources combined into a single response shape.
- Google Ads API provides search volume, CPC, and competition metrics.
- Google SERP API feed difficulty calculation, related-query discovery, and intent classification.
- Our proprietary keywords database — over 8 billion indexed Google queries with monthly history going back several years — backs every discovery endpoint.
- Clickstream data refines the search volume Google Ads returns, supplementing bucketed ranges with exact monthly integers where available.
What is the difference between Keyword Suggestions and Related Keywords endpoints?
Keyword Suggestions runs a full-text match and returns every query in our index that contains your seed phrase. Related Keywords pulls from Google’s “Searches related to” feature and follows the chain to whatever depth you specify. Most keyword research tools leverage both endpoints and merge the results.
Which locations and languages does DataForSEO Labs API support?
DataForSEO Labs API supports a multitude of locations and languages, covering Google’s major regional indexes worldwide. The complete list of supported locations and languages is available through our locations and languages endpoint, including the exact codes your tool sends in each request. We add coverage on a rolling basis, so it’s worth pulling the list at integration time rather than hardcoding it.
How is the search volume in this API different from Google Keyword Planner?
The keyword research endpoints of DataForSEO Labs API returns exact monthly search volume from Google Ads where it's available, plus the historical values. We also offer optional clickstream-enriched and Bing-normalized keyword data that fills in the gaps, giving you options to display in the UI of your SEO software.
What are the rate limits for keyword research endpoints?
The basic account-level limit is 2,000 API calls per minute across all DataForSEO Labs API endpoints. For most keyword research workflows that's headroom you won't have to think about. If you're scaling to a larger rollout and need a higher quota, our support manager will help you arrange one.
Can I use this data in an SEO tool I sell to my own customers?
Yes. Our pricing model is optimized for software builders, and most of our customers ship SEO tools that surface our data to their own end users. The specifics are in our Terms of Service. If you have a non-standard distribution model or an enterprise use case, our team is happy to talk it through.
