# Sample Blog Content (Many Headings for Table of Contents)
Use this in Sanity Studio: create a new **Post**, set title and slug, then in **Body** add the blocks below. For each line that says **H2**, **H3**, or **H4**, use the block style dropdown in the editor to set that heading level. Everything else is **Normal** paragraph text.
Why Index Coverage Matters for SEO
Google can only show pages it has indexed. If your key pages are "Crawled – currently not indexed" or missing entirely, you're losing traffic. Understanding index coverage helps you fix the gaps.
## H2: How Google Decides What to Index
### H3: Crawl budget and priority
Google doesn't crawl every URL on the web equally. It assigns a crawl budget and priority. Important, well-linked pages get crawled more often. Thin or duplicate content gets deprioritized.
### H3: Quality and relevance signals
Content quality, relevance to queries, and user signals (clicks, dwell time) influence whether a page gets indexed and where it ranks. Low-quality or irrelevant pages may be dropped from the index.
### H3: Technical barriers
Blocked by robots.txt, noindex tags, or broken redirects can keep pages out of the index even when the content is good. Always check the technical layer first.
## H2: The Three Buckets: Indexed, Not Indexed, Junk
Indexed URLs
These are the pages Google has added to its index. They can appear in search results. Your goal is to get all important URLs into this bucket.
### H3: Not indexed URLs
Pages Google has crawled but chosen not to index. Common reasons include "Crawled – currently not indexed," "Discovered – currently not indexed," or "Duplicate without user-selected canonical." Each has a different fix.
### H3: Junk URLs
In tools like SEO Labs, "junk" often means URLs that appear in Google Search Console but not in your sitemap. These can be old parameters, duplicate variants, or legacy URLs that dilute your index. Cleaning them up helps Google focus on what matters.
## H2: Step-by-Step: Improving Your Index Coverage
### H3: Audit your current status
Use Google Search Console's Index Coverage (or the new Indexing report) to see how many URLs are indexed, not indexed, or errored. Export the data and segment by reason.
### H3: Fix technical blocks
Remove or adjust robots.txt and noindex where they're blocking good content. Fix redirect chains and ensure canonicals point to the right version.
Improve low-value pages
Merge, redirect, or noindex thin or duplicate content. Add unique value where you want pages to be indexed.
### H3: Monitor and iterate
Re-check coverage after changes. Indexing can take days or weeks. Track trends over time so you can spot new issues early.
## H2: Using GSC Data Over the Long Term
Google only keeps 16 months of data in the standard interface. If you store your own historical GSC data (e.g. with a tool that saves it), you can analyze 3, 5, or 10 years of trends and see the impact of algorithm updates or your own changes.
## H2: Top 10 vs 11–20: Where to Focus
### H3: Protecting page-one rankings
Pages already in the top 10 need to be maintained. Track clicks and impressions so you can react if they drop.
### H3: Capturing 11–20 opportunities
Queries where you rank 11–20 are often the easiest wins. Small improvements in content or relevance can move you to page one and significantly increase clicks.
## H2: Summary and Next Steps
Index coverage is the foundation of organic visibility. Audit your buckets, fix technical and quality issues, and use long-term data to guide decisions. Focus on high-intent URLs and turn "not indexed" into "indexed" where it matters most.

**End of sample.** In Sanity, create each **H2**, **H3**, and **H4** as a block and set the style from the block toolbar. This will populate the Table of Contents on the right when you view the post on your site. The right sidebar (TOC + CTA) is sticky and will stay at the top as you scroll.
