Why Backlinks Don't Get Indexed (and What Our Data Shows)
Only 36.3% of 34,382 tracked placements ended up in Google's index. Why linking pages get skipped and how to raise the share.
A backlink only helps if Google indexes the page it sits on. That sounds obvious, but most link building is still judged by "published", not by "indexed". Our own data shows how big the gap is.
How many links actually get indexed
Across 812 PromoPilot campaigns we tracked 34,382 level-1 and level-2 placements and checked whether the pages carrying them ended up in Google's index. 36.3% were indexed. The rest were published, live and linking, but sitting on pages Google never kept.
Why this matters
A link on a page outside the index passes practically nothing: Google doesn't count what it doesn't store. When a report says "50 links built", the useful question is how many of those 50 pages are indexed.Why linking pages don't get indexed
- Thin or duplicate content. Spun or templated articles are crawled and dropped — "Crawled, currently not indexed".
- No internal links on the platform. A new post on a big blog platform may have no links pointing to it, so Google discovers it late or never.
- Weak or spammy neighbourhoods. Platforms full of low-quality posts get crawled less often.
- noindex on the platform. Some hosts add noindex to new or free accounts — see noindex, nofollow and robots.txt.
How to raise the share of indexed links
- Check indexing of every linking page, not just your own — use the index checker on the URL of the page that links to you.
- Link to your linking pages. This is the whole idea of tiered link building: level-2 links help level-1 pages get crawled — see tier-1 and tier-2.
- Prefer platforms whose pages get indexed. Track it per platform and stop using the ones where most pages never make it in.
- Give it time. Indexing of third-party pages often takes two to six weeks; judge a campaign after that, not on day three.
How PromoPilot handles it
Every placement in a PromoPilot report shows its indexing status, and platforms whose pages consistently fail to get indexed get lower priority in rotation. You can also add priority indexing to a campaign.
FAQ
Does a link on an unindexed page count?
Practically no. Google does not count links from pages it doesn't keep in its index.
How long should I wait before judging?
Two to six weeks for third-party pages. Checking after a few days gives misleadingly low numbers.
What is the fastest way to raise the indexed share?
Publish on platforms whose pages get indexed, and point a few level-2 links at your level-1 pages so Google discovers them.
