You earn a backlink. It goes live. Three months later your rankings have not moved, and when you check, Google has never indexed the page the link sits on. That link has done nothing for you — and it never will.
Link indexing is the least discussed part of link building and one of the biggest sources of wasted budget. Here is how I think about it after eight years of building links in competitive niches.
A link only counts once Google has crawled the page it lives on
This sounds obvious and yet most link reports ignore it. Ahrefs or SEMrush showing a new referring domain means their crawler found it. It says nothing about whether Google has.
If Google has not crawled and indexed that page, the link passes no signal at all. You paid for a placement that exists only in your reporting spreadsheet.
Why links go unindexed
| Reason | What is actually happening | Can you fix it? |
|---|---|---|
| The host page has no internal links | Google has no path to reach it from anywhere on the site | Sometimes — ask the site to link it from a category or archive |
| The site has low crawl priority | Google visits rarely because the site is thin or inactive | Rarely. This is the strongest argument against cheap placements |
| The page is noindex or blocked | A meta tag or robots.txt rule keeps Google out | Yes, if the site owner will change it. Always check before paying |
| The content is thin or duplicated | Google crawls it and chooses not to index it | No — and this is why guest posts on content farms fail |
| The page is brand new | It simply has not been crawled yet | Yes, with time and a few nudges |
| The link is inside JavaScript or a redirect chain | Google may never resolve it to your URL | Sometimes — ask for a plain HTML link |
How to check, in two minutes
- Copy the exact URL of the page your link sits on.
- Search Google for
site:followed by that URL. If nothing comes back, it is not indexed. - For anything you control, use the URL Inspection tool in Google Search Console to see the real crawl and index status.
Do this for a sample of every campaign. If a supplier’s placements are consistently unindexed, you have learned something worth more than the links.
What actually gets links indexed
In order of how reliably they work, in my experience:
- Place links on pages that were always going to be crawled. A link in a live editorial section of an active site gets indexed by default. This is the whole argument for quality over volume.
- Ask the host to link the page internally. One link from their blog index or a related article usually solves it.
- Get the page shared somewhere Google crawls constantly. Real social distribution, a newsletter, a forum where the topic is being discussed.
- Request a recrawl for pages you control. Google documents the process here: Ask Google to recrawl your URLs.
- Build a small number of second-tier links to the host page. Used sparingly and on genuinely good placements, this gives the page its own crawl path.
Where link indexer tools fit — and where they do not
Link indexer services promise to push unindexed links into Google’s index. Some do help, particularly with pages that are simply new and under-linked rather than low quality.
Two things are worth being clear about.
- An indexer cannot rescue a bad link. If Google crawled the page and decided not to index it, the problem is the page, not the crawl. No tool fixes that.
- Some indexers work by building automated link networks pointing at your placements. That is the kind of automated link generation Google names in its spam policies. Know what you are buying.
My own rule: if a placement needs an indexer to get noticed, that is usually the tool telling me something about the placement.
The cheaper fix nobody wants to hear
Buy fewer links from better sites.
Ten placements on active sites with real audiences will be indexed automatically, pass real signal, and survive the next update. A hundred placements on dormant sites will need indexing help, pass almost nothing, and quietly become a liability.
Before any placement, I check three things: is the site actually crawled regularly, does the specific page have internal links, and is there a real audience that might click. If two of the three fail, I do not buy it.
