What the data can and cannot tell you.
Pay per lookup for occasional SEO audits: what one client audit cost through DataForSEO and Serpstat, measured
One client audit (rankings for 50 queries, volumes for the same 50, the domain's ranked keywords, its backlink profile and a 100-page on-page crawl) run through two pay-per-call routes on 29 October 2026, with the settled cost per step and what the API did not return that a suite's screens do.
Does SERP keyword clustering depend on the SERP API? 50 keywords, six runs, measured
The rule people give Claude Code with a SERP API: group keywords whose top 10 results share 5 or more URLs. Applied to the same 50 keywords through nine SERP routes across six runs between 15 September and 15 October 2026, how many keyword pairs each route groups, how far the groups move between runs half an hour apart, and what 1,000 keywords cost per route.
How to check an AI visibility tracker is pulling live answers: seven answer routes, measured
Ten prompts, four of them about September 2026 events, through ChatGPT, Perplexity, Google AI Mode and Gemini, and through the ChatGPT model API with web search off and on. Which answers were live, which came from model memory, and what a tracker has to store to prove the difference.
Are SERP APIs blocked by Google's scraper crackdown? Nine routes, measured
The same 50 queries through Google SERP routes on 15 and 28 September 2026: how many calls failed, whether the google.com/goto redirect reaches the URL field, and why routes that agreed on 15 September now return different result lists for the same query.
What SEO data you can actually get for free, and where free runs out
Free tiers, one-off grants and trials for Google results, keyword volume and backlinks, read from each provider's own pricing page on one day: how many calls, for how long, and the first paid step.
Is there an API for Google AI Overviews? What three routes actually return
Google publishes no AI Overview API. Three third-party routes claim to return the block: a rendered-page capture, a SERP API flag, and a two-step token exchange. Measured on 90 and 100 requests on the same day: how often the overview came back, with what, and at what price.
