What is an Indexability Score Calculator?
The Indexability Score Calculator is an advanced technical SEO tool that determines the mathematical probability of Google crawling and indexing your specific webpage. It separates ranking factors into two distinct categories: fatal technical errors that block indexation entirely, and content quality signals that dictate whether Google finds the page valuable enough to store in its database.
Category 1: Critical Technical Gates (Pass/Fail)
Before search engines evaluate the quality of your video or article, they must successfully pass through a series of technical gates. If a page fails any of these checks, its Indexability Score drops immediately to 0%, meaning it is mathematically impossible for the page to rank:
- 404 HTTP Status Errors: The server must return a 200 OK status code. If the page is broken or heavily redirected (loops), crawlers will abandon it.
- Noindex Directives: If your HTML header contains a
<meta name="robots" content="noindex">tag, or your HTTP headers block indexing, Google will obey the command and drop the page from the SERPs. - Canonical Mismatches: If Page A contains a canonical tag pointing to Page B, Google will ignore Page A. The URL must be self-referencing or lack a canonical tag entirely to be indexed.
Category 2: Quality & On-Page Signals (Weighted Points)
In recent years, passing technical gates is no longer enough to guarantee indexation. To prevent database bloat, Google aggressively uses the "Crawled - currently not indexed" status for pages it deems low-value. The calculator awards up to 100 points based on these quality signals:
- Content Length (30 Pts): Pages with thin content (just a video player and no text) are frequently rejected by the indexer. Higher word counts drastically improve indexation rates.
- Heading Structure & Meta Data (50 Pts Combined): Properly formatted H1/H2 tags and optimized meta descriptions prove to the crawler that the page is structured, authoritative, and ready for human readers.
- Mobile-Friendliness (20 Pts): With mobile-first indexing fully rolled out, pages that break on mobile viewports are actively suppressed from the search index.
Frequently Asked Questions
My score is 100%, but my page still isn't indexed. Why?
While an optimized page has the highest probability of indexing, it still requires crawl budget. If your website is entirely brand new and lacks internal linking, Googlebot may simply not have discovered the URL yet. Ensure you have submitted your XML sitemap to Google Search Console to speed up the process.
Can I fix a 0% score?
Yes. A 0% score simply means there is a technical roadblock. Remove the accidental "noindex" tag, fix the broken URL, or correct your canonical structure. Once the technical gate is resolved, your score will jump back up based on your content quality.
