Google Indexometer
- 20 000 domains
- 250 000 URLs
Methodology (summary)
- Domains selected evenly from the Tranco list (top 1M websites).
- ~50 URLs per domain sampled from sitemaps, mixing older and newer entries.
- Each URL is tested to determine if it’s indexed; results are aggregated.
Why this matters
Indexing is the invisible backbone of search. If Google doesn’t index your pages, they can’t rank, no matter how well-optimized they are. Yet there’s been no public benchmark of how much of the web Google actually indexes.
The Indexometer changes that. Each month we sample a large set of pages across thousands of domains, and test whether Google has indexed them.
What is IndexCheckr?
While the Indexometer gives a global view of Google’s indexing rate, IndexCheckr is the tool that lets you monitor indexing for your own site or your backlinks.
- Track the index status of all your pages in real time.
- Schedule automatic rechecks and get email alerts when pages are indexed or de-indexed.
- Export reports, use our API, and send non-indexed pages to indexing services.
Thousands of SEOs and site owners use IndexCheckr to make sure their content actually appears in Google search results.
Methodology (full)
- Domain selection. We select ~20 000 domains from the Tranco list, evenly distributed between rank 100 and rank 1 000 000 to cover large, mid-size, and long-tail sites.
- URL sampling. From each domain’s public XML sitemap(s), we collect ~50 URLs. When multiple sitemaps exist, we select from across the set (older and newer entries) to avoid recency bias. Non-HTML formats (e.g., PDFs, images, feeds) and obvious duplicates are excluded.
- Indexing check. Each sampled URL is tested once to determine whether it is currently indexed. We include URLs even if they return HTTP errors (e.g., 404/500) because such pages can still appear in Google’s index. Unlike the main IndexCheckr tool, which may use multiple checks for maximum accuracy, the Indexometer relies on a single check per URL for scalability. This may introduce a very small number of false negatives, making the rate slightly conservative.
- Aggregation. Results are combined across all sampled domains. The headline Indexometer figure is the percentage of tested URLs that are indexed.
- Repetition. The process repeats monthly with a fresh sample of domains and URLs. Over time this produces a timeline showing whether the indexing rate is rising, falling, or stable.
