Choose location and language before buying SEO data
Guides
Define the market before researching keywords or rankings. Resolve location codes for free, check endpoint support and keep comparisons consistent.
A useful SEO query starts with the market you want to understand. Write down the search topic, target country or city, language and decision the result should inform. A national expansion plan and a local shop visibility check need different geographic scopes. Do not let an API default silently choose the market for you.
Location and language are separate settings. DataForSEO documents separate location and language lists for Google SERP requests. A place identifies the geographic scope; a language setting does not identify a country. Treat both as explicit inputs when the chosen API supports them.
On CONNSKILL, the free GET /v1/locations lookup helps resolve names before a paid request. Use q to filter a name. The country parameter switches the lookup to places within that country. Read the returned name and geographic context before copying a location_code; a similar place name is not enough to identify your intended market.
A lookup result does not prove that every SEO endpoint supports the same geography or language combination. Check the selected route in the current OpenAPI document and its provider documentation. If city-level input is unsupported, stop or explicitly choose a supported broader scope. Do not silently label national data as a local result.
For repeatable comparisons, keep the query, location, language and any supported device setting consistent. Save those inputs with the observation time and source. If the settings change, label the new series separately so a configuration change is not mistaken for a ranking change.
Before authorizing payment, also read the current service status. A valid location code does not make a paused route available. Resolve the market and contract first, then buy only a currently available result that answers the original question.
