Keyword research FAQ
Quick answers to the questions people ask when they're choosing a keyword research tool.
What is keyword research?
Keyword research is the process of finding the search queries real people type into Google, then assessing which of those queries your site can realistically rank for given the current top 10. Good keyword research weighs volume, intent, and competitive weakness — not just search volume.
Is SERPTool a free keyword research tool?
SERPTool gives every new account 40 free credits on signup — enough to research several keywords and run a small bulk analysis with no card on file. Beyond that, paid plans start at $23/mo and credit packs let you pay for only the keyword research you run.
How is SERPTool different from Ahrefs, Semrush, or Ubersuggest?
Traditional keyword research tools average authority signals into a single Keyword Difficulty number. SERPTool scores 17 SERP-result weakness signals across the live top 10 — so you find keywords where the current results have real, exploitable gaps instead of relying on aggregate difficulty.
How do I do keyword research for a brand-new website?
For a new domain with no authority, ignore head-term volume. Filter for keywords where the weakest top-10 result has a low domain score, look for UGC-heavy SERPs (Reddit, Quora) you can outrank with structured content, and stack long-tail variants. SERPTool exposes all three signals per keyword.
Can I do bulk keyword research with SERPTool?
Yes. SERPTool runs bulk keyword research for up to 1,000 keywords in a single analysis. Each keyword gets live SERP data, domain/page scores for every result, an Opportunity Score (0–100), and weakness signals — exportable as CSV for downstream content briefs.
Does keyword research still work in 2026 with AI Overviews?
Yes, but the criteria changed. AI Overviews eat clicks on informational head terms, so keyword research now leans harder on commercial-intent long-tail, question-based formats, and SERPs where AI summaries are absent. SERPTool surfaces AI Mentions per keyword so you can avoid the dead zones.
