How to index backlinks

Exact integers from the public ledger: 413 attempts, 2026-06-25 to 2026-07-31. Click a column header to sort.

If your link sits on an ordinary blog, directory or guest post, the table above has no measured odds for you, since the ledger only covers the hosts this pipeline publishes on, but the same four readings decide your case, and you can take all four in minutes. Google finds a page by extracting a link from a page it already knows or from a sitemap, so check whether the host's robots.txt declares a Sitemap line and whether the site's own pages, the front page, a category page, an author archive, link to the page carrying your link. An established blog usually passes both, which is the structural reason a guest post on a linked up blog behaves like the mataroa row and a paste and go page behaves like the telegra.ph row. Then read the page itself. Your link must be an <a> element with an href, the page must return HTTP 200 with Googlebot not blocked, and it must carry no noindex in the robots meta or the X-Robots-Tag header, because if noindex is present, Google drops the page regardless of who links to it, and waiting cannot fix that. The checker at the top of this page reads the markup half of this for you.

Make the link crawlable

Google can only crawl a link that is an <a> HTML element with an href attribute. A link inserted by JavaScript is fine as long as it ends up as that same <a href> markup, but Google says it can't reliably extract URLs from anchors without an href or from other tags acting as links through script events. Rendering is a separate step. Google renders the page and runs the JavaScript it finds with a recent version of Chrome, and a page can sit in the render queue for a few seconds or longer than that. So a link that only exists after a script runs is crawlable, just later.

Make sure the host page can be indexed

Google's minimum for a page to be eligible for Search is that Googlebot isn't blocked, the page returns HTTP 200, and the page has indexable content. Any content behind a 5xx response is ignored. A noindex rule matters more than anything else on this list, because when Googlebot crawls a page carrying it Google drops the page from Search results regardless of whether other sites link to it. Your backlink can be a perfect <a href> and still live on a page Google won't keep. The rule can arrive as a meta tag or as an X-Robots-Tag: noindex HTTP header, and the header form won't show in pasted HTML, which is why the checker tells you to look at response headers. When no robots meta rule is present at all, Google applies no restrictions on indexing or serving. A value of none is equivalent to noindex, nofollow.

Give Google a route to the page

Google primarily finds pages through links from other pages it already crawled. A page with a backlink on it still needs its own inbound link or a sitemap entry. Google says a sitemap may be needed when a site is new and has few external links to it, and a sitemap helps discovery but doesn't guarantee that everything in it gets crawled and indexed. The simplest way to publish one is a Sitemap line in robots.txt, which Google finds the next time it crawls that file, and the line must be a fully qualified URL including protocol and host. That's the line two of the six probed hosts carry and four don't. On a host you don't control, the route has to come from the host's own linking, as mataroa and njump do, or from a link somewhere else that Google already knows.

Asking for a crawl, and who is allowed to ask

For individual URLs Google says to use the URL Inspection tool, and for large numbers of URLs to submit a sitemap instead. The tool has a daily limit of inspection requests for each property that you own, which settles the backlink question. You can inspect and submit pages on properties you own, not the page on someone else's host that links to you. Requesting a recrawl multiple times for the same URL won't get it crawled any faster, crawling can take anywhere from a few days to a few weeks, and a request doesn't guarantee inclusion in search results, quickly or at all. Google's Indexing API isn't a route either, since it can only be used to crawl pages with JobPosting or BroadcastEvent structured data. IndexNow accepts batches of URLs in a single POST and shares them with all other participating search engines, but its FAQ says submitting a URL does not guarantee immediate indexing, and an HTTP 200 reply only indicates the engine received the URL.

What Google calls link spam

Google defines link spam as creating links to or from a site primarily to manipulate search rankings, and its examples include using automated programs or services to create links to your site, forum comments with optimized links in the post or signature, and buying or selling links for ranking purposes. The same policy says paid or exchanged links aren't a violation as long as they're qualified with rel=nofollow or rel=sponsored. Google asks that advertisements and paid placements carry rel=sponsored and recommends rel=ugc for user generated links such as comments and forum posts. The pipeline behind this site records the served rel value on every ledger row, and a row may only say live after a post-publish re-fetch has read that attribute off the served HTML.

How to tell whether the backlink got indexed

A site: search is a weak instrument. Google says the operator doesn't necessarily return all URLs indexed under a prefix and a bare site: query doesn't rank the results. For your own property, the Search Console Links report includes links Google has found over time, and its Top linking sites table shows which sites contain the most backlinks to your site, so a backlink listed there is one Google has found. The report isn't a comprehensive list of every link. Two statuses in the Page indexing report describe a linking page that hasn't made it. Discovered, currently not indexed means the page was found by Google but not crawled yet. Crawled, currently not indexed means the page was crawled but not indexed, and may or may not be indexed later, and Google says there's no need to resubmit it for crawling. Neither status can be tested in the URL Inspection live test.

How we measured this

Each Google statement on this page links to the Search Central or Search Console Help page it was read from. The six host rows come from direct fetches by this site's fetcher on 2026-08-29, with robots.txt requested under a Googlebot user agent, and the sitemap coverage percentage is recomputed in code from those six fetches rather than typed into the page. A cell that says not probed means the fetcher didn't test that property, not that the host lacks it. The platform odds table is recomputed by script from data/ledger.csv, the pipeline's own 413 row operating ledger, in which every row carries a verified outcome status. LIVE means the published page was re-fetched, returned HTTP 200, served the anchor, and a crawl path to it existed. The ledger file is handed to any buyer who asks, so every figure on this page can be recomputed independently. The six host rows and the coverage percentage describe the same fixed probe set. The platform odds table is a different, larger measurement, recomputed by script from the 413 row ledger file itself, with its folding rule printed beside it.

Questions people ask about indexing backlinks

How long does it take for a backlink to be indexed

Google says it cannot make predictions or guarantees about when or if a URL will be crawled or indexed. The only range Google itself states is a few days to a few weeks, and that is for a requested recrawl of a page on a property you own. The 48 hour and 10 week figures published by pages ranking for this query are numbers for something Google says cannot be predicted. What you can do in minutes is remove the blockers in the sequence at the top of this page, and read the measured odds for your host in the platform table.

Do nofollow backlinks get indexed

Google says links marked sponsored, ugc or nofollow will generally not be followed, but the linked page may still be found through sitemaps or links from other sites. For crawling and indexing, nofollow became a hint as of March 1, 2020. So a nofollow backlink isn't a crawl path you can count on, and it doesn't stop the page from being found another way.

Can I submit someone else's page to URL Inspection

No. Inspection and index requests are counted per property that you own, so the page on another host that links to you is outside the tool. What you can submit is your own page, and Google's guidance for that is URL Inspection for a few URLs and a sitemap for many.

Discovered but currently not indexed

The status means Google found the page but hasn't crawled it yet. Google lists a site that isn't well connected through multiple links from other sites among the reasons a page isn't indexed, and it says its crawling resources are extensive but finite.

IndexNow and Google

The IndexNow FAQ names Bing, Naver, Seznam.cz, Yandex and Yep among the engines that accept submissions, and after a submission the engine decides whether to crawl based on its crawl quota, scheduling logic and quality signals. Google's own documentation points to URL Inspection and sitemaps.

Backlink indexing services

Google states there's no way to force an index update, and it lists using automated programs or services to create links to your site as link spam. Whatever a service promises, the crawl decision stays with Google, which doesn't guarantee it will crawl, index or serve a page, even one that follows its own guidelines.

Disclosures

No ranking or traffic outcome is promised on any page.
