Do backlinks need to be indexed? How to get yours noticed

A backlink can only pass any value if Google knows about it. If the page that holds your link is never crawled, the link might as well not exist. This is why link builders care about whether the pages linking to them are indexed.

Why some backlinks are never found

• The linking page is new and nothing links to it, so crawlers have no path to it.
• The linking site is weak or rarely crawled, so new pages wait a long time.
• The page is thin or low value, so Google crawls it and decides not to keep it.
• The link is on a page that blocks crawling or carries a noindex tag.

How to make a backlink more likely to be found

1. Prefer links on pages that are already indexed and regularly crawled. Check first, then ask for the link.
2. Get links on pages that other pages link to. A link on an orphan page is the hardest to discover.
3. Share the linking page where crawlers go: an active social profile, a relevant community post, or your own site's blog roundup.
4. Submit the linking URL for crawling. Submission tools exist for exactly this: they make it more likely a crawler visits the page soon.
5. Check later. If the linking page itself is still not indexed after a few weeks, the page, not the link, is the problem.

Quality still decides

A handful of links on real, useful pages beats hundreds of links on pages that Google ignores. Put effort into where the link lives before spending effort on getting it crawled.

Check whether the linking page is indexed first

Before you spend any effort, check the page that holds your link, not your own page. Search for the exact URL with the site: operator, or open the page and look for signs it is crawled, such as a recent cache or other search results pointing to it. If the linking page is not indexed, your link cannot count yet.

A simple workflow

1. List your backlinks and the exact URLs of the pages they sit on.
2. Check which of those pages appear in Google.
3. For pages that do not, look for reasons: noindex, a robots.txt block, thin content, no internal links.
4. Where the page is fine but undiscovered, submit it for crawling and link to it from somewhere crawled.
5. Re-check after a few weeks and keep a record of which links were picked up.

Mistakes to avoid

• Building bulk links on throwaway sites just to have something to index. Search engines are good at ignoring these, and some can hurt.
• Pointing many low-quality links at your links ('tiered link building') hoping to push them. It rarely works and can create risk.
• Treating 'indexed' as 'valuable'. A link on an indexed but useless page still carries little weight.

Realistic expectations

Some links on pages with real traffic are found in days without any help. Links on obscure pages can take weeks or never appear. A submission tool can improve the odds of a crawler visiting the page soon, but it cannot make a poor page worth keeping. Your best results come from earning links on pages that were going to be crawled anyway.
