SERP Checker & Comparison
Compare search results from multiple data sources (Google API, Google SERP, Bing SERP, ChatGPT) and visualize ranking overlap with an interactive heatmap
Frequently Asked Questions
A SERP (Search Engine Results Page) checker allows you to preview search results from multiple sources for any keyword. It helps SEO and GEO professionals analyze rankings, understand search intent, compare different data providers, and monitor competitor positions across different regions and AI platforms.
Our tool provides four data sources: Google API (Custom Search API), Google SERP (real Google results), Bing SERP (real Bing results), and ChatGPT (AI-powered web search with citations). Each source may return different results due to different crawling methods, timing, and algorithms, making comparison valuable for SEO and GEO analysis.
The Country setting boosts results relevant to that region but does not strictly restrict to only that country. This is intentional - strict country filtering would exclude important global resources like Wikipedia. For example, searching with "Thailand" selected will prioritize Thai-relevant results while still showing authoritative international sources. The Language setting tells search engines which language results to prioritize (it does not translate results). Note: The Language setting does not affect ChatGPT results, which responds based on the query language and its own language detection.
The overlap shows what percentage of one source's results appear in another. For example, if 3 out of 10 Google results also appear in ChatGPT, the "Google → ChatGPT" cell shows 30%. This is directional - "ChatGPT → Google" may show a different percentage since ChatGPT might cite different domains.
The heatmap is a square matrix where each cell shows "% of row's results found in column". Read it as: "X% of [Row Source] results appear in [Column Source]". The matrix is asymmetric because overlap is directional. Green (80-100%) means high overlap, red (0-19%) means low. The diagonal shows "-" since comparing a source to itself is always 100%.
Different sources use different methods: Google Custom Search API uses a programmable search engine, the Google SERP and Bing SERP sources crawl actual search results, and ChatGPT uses AI-powered web search that may cite authoritative sources regardless of their search ranking. Results also vary based on location, timing, and personalization.
ChatGPT uses AI web search to find and cite relevant sources, which may differ significantly from traditional search engine rankings. It prioritizes authoritative and informative content based on the query context. The full ChatGPT response is shown along with extracted citation links for comparison with traditional SERP results.
The table shows all domains from your search results with their ranking positions in each source. Green highlighted rows indicate domains appearing in all selected sources. Numbers show the position (1-10): green for top 3, yellow for top 5, and gray for positions 6-10. A dash (-) means the domain did not appear in that source.
Yes! Compare results across sources to identify competitors that rank well consistently. Domains appearing in all sources at high positions have strong visibility. For GEO strategy, note which competitors ChatGPT cites - these may influence AI-generated recommendations regardless of traditional search rankings.
