If you mean how to get a backlink you created indexed by Google, the key point is that you cannot force Google to index a backlink. Google decides which pages to crawl and index. What you can do is make the page containing the backlink easier for Google to discover and consider.
Steps to improve backlink indexing
Make sure the linking page is indexable
Check that the page isn't blocked by
robots.txt.Make sure it doesn't contain a
noindexdirective.The page should be publicly accessible without a login.
Check whether Google already knows the page
Search Google for:
site:example.com/page-urlIf the page appears, it may already be indexed. Remember that a
site:search isn't a definitive indexing test.Add internal links
Link to the page containing your backlink from other relevant, already-discovered pages on the same website. This can help search engines discover it.
Create useful, original content
A backlink placed on a thin, duplicated, automatically generated, or low-value page is less useful than one appearing naturally within genuinely helpful content.
Submit the URL through Google Search Console
If you control the website containing the backlink, open Google Search Console, use URL Inspection, and request indexing when the option is available.
This is a request to crawl the page—not a guarantee that Google will index it.
Earn links to the linking page
If appropriate, other relevant pages can link naturally to the page containing your backlink. This can improve discovery and establish the page within the site's overall link structure.
Be patient
Google doesn't necessarily crawl newly published pages immediately. Indexing can take days or longer depending on the site, page quality, crawl patterns, and other factors.
Avoid "instant backlink indexing" services
Be cautious about services promising 100% Google indexing, thousands of automated links, or guaranteed rankings. Automated link-building and low-quality link schemes can create SEO problems rather than solve them.
Also, indexed doesn't mean valuable. A backlink can be on a Google-indexed page but still provide little SEO benefit if the page is irrelevant, low quality, or the link has attributes such as
A simple workflow
Publish quality page → make sure it's indexable → add internal links → request indexing in Search Console → wait for crawling → check indexing → monitor the backlink.
If you tell me where your backlink is placed (guest post, profile, directory, Web 2.0, forum, social site, etc.), I can give you the best indexing method for that specific type of backlink.
