To speed up link indexing, nudge Google toward the donor page: strengthen it with internal and external signals, submit the URL for recrawl in Google Search Console, and if needed add tier-2 links or a paid indexing service. You can check that a link is counted with the site: operator, in Search Console for your own site, and in Ahrefs or Serpstat reports. Keep in mind: a purchased link only starts affecting rankings after the donor page with it gets into the index. Until then, it effectively does nothing.
Key points in 30 seconds
- A link affects rankings only after the donor page is indexed.
- Common causes of slow indexing: a small crawl budget and low donor trust.
- Free methods: internal linking, content updates, sharing the URL, recrawl requests in Search Console.
- Paid methods: indexing services and tier-2 links to the donor page.
- You check whether a link is counted via site:, Google Search Console, and Ahrefs / Serpstat reports.
How Google discovers and crawls the page with your link
To understand what you can and can’t speed up, it helps to know the mechanism. Google describes how Search works as three consecutive stages: crawling, indexing and serving results. A link to your site only “switches on” after the second stage, when the donor page hasn’t just been visited by the bot but its content has been processed and stored in the index.
- Discovery. Google learns about a new URL, most often through links from pages it already knows and less often through a sitemap. A new forum thread gets discovered when the bot next opens the forum section or homepage where that thread appeared.
- Crawling. Googlebot downloads the page. If it’s blocked in robots.txt, returns an error or is only available after logging in, the process stops here.
- Indexing. Google analyzes the text, links and meta tags and decides whether the page is worth storing. Not every crawled page makes it into the index: duplicates and low-value pages may be dropped.
- Link processing. Links from an indexed page are factored into the signals for your site. This doesn’t happen the instant the page is indexed but with some delay.
One more nuance: Google can only follow a link that’s technically crawlable. According to Google’s link best practices, a link should be an <a> element with an href attribute, and the anchor text should ideally be descriptive, relevant and concise. Links injected via JavaScript handlers without an href, buttons, or “expandable” blocks that only load after a click may simply be invisible to the bot. Googlebot isn’t the curious type; it doesn’t press buttons to see what happens.
Why a link goes unindexed for months
Google has a limited crawl budget for each site, meaning the number of pages the bot is willing to crawl over a given period. If the donor page with your link sits deep in the site structure, is rarely updated, and has almost no internal links, the bot can take months to reach it. The lower the donor’s trust and traffic, the less often it gets crawled.
Google’s documentation on crawl budget explains that the topic matters mainly for large sites. For a small abandoned forum, the problem is different: the bot rarely visits simply because nothing has changed on the site for a long time and few sites link to it.
Other common causes:
- the donor page is an “orphan”: no internal links point to it;
- thin or duplicate content, so Google doesn’t consider the page valuable;
- a noindex tag or a robots.txt block (sometimes entire comment sections are closed this way);
- an outdated or missing sitemap on the donor;
- the page was just created: it simply needs time.
If pages of your own site are dropping out of the index too, not just links, work through the causes with our separate indexing diagnostics checklist. How the bot allocates crawling and how to read indexing reports is covered in detail in our article on setting up Google Search Console.
Dead forums and boards with no external links
In crowd marketing, the most common reason for links that “never get indexed” isn’t technical at all; it’s the choice of platforms. Google rarely visits a forum where nobody posts. A board whose last post dates from 2019 isn’t a donor anymore; it’s a museum, and the bot only drops by for the occasional guided tour. A thread created there today may stay out of the index for months and then drop out along with the whole section. Add moderation to that: on many forums external links are deleted within a few days, so even if the bot does come, the link is already gone.
From our practice
When we checked 16,500 forums in October 2026, 90% of them responded, but “responds” doesn’t mean “alive”. Of the 7,872 forums with a visible last-post date, only 58% had new posts in the previous 3 months. And among the forums where we could inspect threads, 68% had no external links at all in the threads we checked: moderators remove them or don’t let them through. In other words, on roughly every second forum a link either won’t survive until the bot arrives or will wait a very long time for it. That’s why we first select live boards with active discussions and only then place links there, not the other way round.
What actually speeds up indexing
The most effective methods work before the link even exists: they’re about choosing the donor and the placement. “Reviving” a link on a weak site later is far harder than putting it somewhere the bot visits every day in the first place.
1. A quality donor that gets crawled often
The signs of such a site are simple: fresh posts every day, section pages in the index, new threads showing up in search within a few days. Check this with the site: operator for a few recent threads: if week-old threads are already findable, the donor is crawled well. You can see the donor’s key indicators in our free donor site checker.
2. Internal links on the donor
A new forum thread automatically appears on the section page and in the “Latest posts” block, and often on the homepage. Those internal links are what lead the bot to your comment. That’s why a reply in an active thread at the top of a section gets indexed faster than a comment in a long-forgotten thread on page twenty of the archive.
3. Active discussions
Every new reply changes the page, bumps the thread up the section and gives the bot a reason to come back. A relevant comment that other members respond to works better than a “post into the void”: it gets indexed faster and lives longer, because moderators don’t delete useful posts.
4. Time
The most underrated factor, and the only one you can’t buy. Even on a good donor, some time passes between placement and the link appearing in reports, and that’s normal. Most “not indexed” problems in the first weeks are really just ordinary waiting.
Ways to speed up indexing, from free to paid
| Method | Cost | Speed | Caveat |
| Internal linking to the donor page | Free | Medium | Requires access to the donor |
| Updating the donor’s content | Free | Medium | Not always possible |
| Sharing the URL on social media and channels | Free | Low–medium | Inconsistent effect |
| Recrawl request in Search Console | Free | High | Only for your own sites |
| Tier-2 links to the donor | Low | Medium | No spam, do it carefully |
| Indexing services | Paid | High | No guaranteed results |
Start with the free methods. The most controllable one is internal linking: if you have access to the donor page (for example, it’s your second site or a friendly site), link to it from a page the bot crawls often. Publishing fresh content on the donor page also triggers a recrawl.
The URL Inspection tool in Google Search Console and the “Request indexing” button only work for sites verified in your account, meaning your own site, not someone else’s donor. For third-party donors you’re left with external signals: sharing the URL, tier-2 links and paid indexing services. The latter come with no guarantees, so be skeptical of “100% indexing” promises. If that button existed, Google would be using it on itself.
What Google says about recrawl requests
Google’s help page “Ask Google to recrawl your URLs” describes two official methods: the URL Inspection tool for individual pages and a sitemap for large numbers of URLs. Both are only available to the property owner in Search Console. Google also warns that recrawling can take anywhere from a few days to a few weeks.
For link building, this leads to an important practical conclusion: URL Inspection is useful when you’ve updated your own page that new links point to, but it can’t help index a thread on someone else’s forum. Services that promise to “submit your backlinks to Search Console” have no such ability, because they don’t own the donor sites.
What doesn’t work or carries risk
There’s a whole industry of “accelerators” around link indexing. Some are useless, some are dangerous:
- Mass pinging. Sending a list of URLs to dozens of ping services was common many years ago. Today Google doesn’t rely on such signals to discover pages, so the result is usually zero.
- Spammy indexers. Some paid services “index” links by pointing thousands of automated backlinks from junk sites at them. Google explicitly classifies automated programs that create links as link spam. That kind of “tier-2” can make things worse: the donor gets a spammy profile, and your site sits at the end of that chain.
- Profile and directory blasts “for indexing”. Same thing, different packaging. Profile pages mostly don’t get indexed themselves, so links from them don’t speed anything up.
- Clicking “Request indexing” over and over. This applies to your own site. In our experience, repeated requests for the same URL don’t speed things up; they only use up your daily quota. Mashing the elevator button doesn’t bring it any faster either.
If you do use tier-2, build it as carefully as the first tier: relevant mentions of the donor page from live sites, not automated blasts. More on this setup in tier 1, tier 2, tier 3: why you need a tiered link structure.
How to check that a link is counted
The check has two steps: first confirm that the donor page itself is indexed, then confirm that Google sees your link on it.
- The site: operator. Search for site:domen.com/donor-page. If the page shows up in the results, it’s indexed.
- Google Search Console. For your site, open the Links report → External links: it shows the domains Google has counted. The donor appearing in this report is the most reliable sign the link is counted.
- Ahrefs / Serpstat. In the backlinks report, look at the link status and the donor’s indexing flag.
- Manual check. Open the donor page and make sure the link is in place, dofollow (if that was the plan) and not hidden inside a noindex block.
Allow for a delay: even an indexed link doesn’t affect rankings right away, since Google needs time to recalculate signals.
Limits of the site: operator
The site: operator is handy for a quick check, but it isn’t a precise diagnostic tool. It shows a sample of pages rather than a complete list, and it can both miss an indexed page and temporarily show one that’s already been removed. So read the result this way: “found” means the page is almost certainly indexed; “not found” isn’t a verdict yet, so check again in a few days and look at other sources. For an exact check of your own pages, use URL Inspection in Search Console; for checking donors in bulk, use the Links report in Search Console and third-party tools.
In its guide on getting Google to index your pages, Ahrefs walks through the typical reasons a page stays out of the index. The logic is simple: fix the cause first (noindex, blocks, weak internal linking, low content value) rather than looking for a “speed-up button”. The same principle applies to donors.
Realistic timelines
Google doesn’t publish exact figures, so go by the donor type rather than service promises:
| Donor type | What to expect | What to do |
| Live forum with daily posts, active thread | Usually from a few days to a few weeks | Just wait and check |
| Live forum, old thread deep in a section | Weeks, sometimes longer | Choose active threads over archived ones |
| Low-activity forum with no new posts | May never get indexed | Don’t place links there, or replace the donor |
| Your own site after a page update | A few days to a few weeks (per Google’s help page) | URL Inspection or sitemap in Search Console |
If the donor page still isn’t indexed after 4–6 weeks while the site itself is alive, check for technical causes (noindex, robots.txt, closed sections). If the site is dead, there’s no point waiting longer. Also remember that after indexing, the link needs more time to affect rankings: don’t judge the effect of a purchase earlier than a few months in. For other reasons bought links “don’t work”, see bought backlinks, no results: 8 reasons.
What to do if a link drops out of the index
Links drop out of the index more often than anyone would like. First, find the cause:
- the donor page was deleted, set to noindex, or returns a 404;
- moderators deleted your comment or placement;
- the donor lost trust or got hit with penalties and is no longer crawled;
- the site owner removed the link.
Action plan: if the problem is on the donor’s side but the site is still alive, try to get it recrawled with external signals and tier-2 links. If the placement was deleted or the site has degraded, don’t waste effort reviving it; replace the donor with a new one. Regular profile monitoring helps you catch drop-offs in time: set up alerts in Ahrefs or check the Links report in Search Console once a month.
From our practice
We give clients a report with the URL of every placement precisely so they can verify indexing independently of us. If moderators delete a link, we replace it free of charge. To keep replacements to a minimum, our selection takes into account what our forum check showed: external links are far from universal, and among forums that do allow them, 49% are dofollow, 32% nofollow or ugc, 10% mixed and 8% go through a redirect. A redirected or nofollow link gives your site less, so we count such boards separately rather than passing them off as full-value placements.
Checklist: speeding up and checking indexing
- Make sure the donor page is open for indexing (no noindex/robots block).
- Strengthen the donor with an internal link and fresh content.
- For your own sites, submit the URL for recrawl in Search Console.
- For third-party donors, use tier-2 links and, if needed, an indexing service.
- Check that the link is counted via site: and the Links report in Search Console.
- Monitor your profile for drop-offs once a month.
If you buy links, make sure the contractor is responsible not just for placement but for indexing too: an unindexed link is wasted budget. When you order crowd link placement from us, we check that every site is live and indexed, and we report on whether each link is actually counted. How links affect rankings in general is covered in our core link building guide.
