We Built 3,790 Free Backlinks by Hand. Here's How Many Were Still Live Months Later

Everyone has an opinion on free backlinks. "They don't last." "The platform deletes them in a month." "Profile links are worthless." What nobody brings is data - because measuring it means actually building thousands of links and then going back to check whether they survived. So we did that.

Over three months we hand-placed 3,790 backlinks across more than 890 free platforms - profile pages, article-submission sites, forums, classifieds, image and doc hosts. Then, months after each placement, we re-crawled every single URL to see what was still live. This post is the result: the first-party survival data behind the opinions.

Key takeaways

• Of the 2,281 links we could conclusively verify, 87.9% were still live months after we built them. Free links last far better than their reputation suggests.
• Only 275 links (7.3% of everything we crawled) were confirmed removed. The "free links vanish" narrative is mostly wrong.
• Survival depends heavily on type: profile creation 95%, image 94%, article submission 90% - but classified ads 70% and forum links just 56%.
• 37.4% of URLs were bot-blocked (the platform returned a 403/429 to our crawler). That is not a dead link - it means we could not judge it either way - so we excluded those from the survival rate entirely rather than count them as dead.
• Survival is not the same as value. A live link can still be nofollow, unindexed, or on a zero-traffic page. This study measures one thing - does the link still exist - honestly and nothing more.

How we ran this

The placements. Between February and April 2026 our team manually created accounts and published links on free platforms across seven categories. These are the same kinds of sites in our Web 2.0 and foundational backlinks lists - the free, do-it-yourself layer every SaaS starts with. Every placement was logged with its live URL.

The re-crawl. In July 2026 - three to five months after placement - we fetched all 3,790 unique URLs and recorded the HTTP status of each. We classified every result into one of four buckets:

• Live - a 2xx response. The page (and our link) still resolves.
• Dead - a 404 or 410. The page is gone; the link was removed.
• Couldn't verify - a 403 or 429. The platform blocks automated requests, so we cannot see the page at all. This says nothing about whether the link is live.
• Error - timeouts and 5xx responses. Inconclusive.

The honest part. 37.4% of our URLs came back bot-blocked - heavily on the big platforms (LinkedIn, Medium, Quora) that aggressively refuse crawlers. A lazier study would count those as "dead" and report a scary-low survival number, or count them as "live" and inflate it. We do neither. The survival rate below is calculated only on the 2,281 links we could conclusively judge (live + dead). Everything else is reported but excluded from the percentage.

The headline: free links survive better than anyone admits

87.9% of conclusively-checked links were still live. Put the other way: after a full quarter or more, fewer than 1 in 8 verifiable placements had been removed, and only 7.3% of the entire dataset was confirmed dead.

That contradicts the loudest advice in SEO forums. The links did not evaporate. Platforms did not mass-delete profiles. For the foundational, entity-building job these links do - making your brand legible across the web - they are far more durable than their reputation.

But the average hides the real lesson, which is that type decides everything.

Survival by link type

Link type	Conclusively checked	Still live
Profile creation	444	95%
Image sharing	31	94%
Article submission	851	90%
Directory	19	89%
Classified ads	79	70%
Forum	61	56%

Profiles and articles are the durable core. A claimed profile page or a published article sits on your own account; nobody has a reason to remove it. These two categories - which are also the bulk of any free link campaign - held above 90%.

Forum and classified links are fragile. Forum links died at eight times the rate of profile links (44% gone vs 5%). That fits how those platforms work: threads get moderated, pruned, or closed, and a signature or comment link goes with them. Classified ads are worse by design - listings expire. If your link's whole host is a 30-day ad, a 30% death rate months later is the system working as intended, not a fluke.

Platform-level extremes

Aggregating by platform (where we had 20+ conclusive checks) makes the split even starker:

• 100% survival: blogging and publishing platforms - justpaste.it, sites.google.com, paragraph.com, differ.blog, feedingtrends.com, coinmarketcap.com community, and others. Publish-and-forget content held perfectly.
• ~98-100%: dev.to and LinkedIn - the platforms with the strongest reason to keep your content also keep your link.
• 0% survival: classifiedads.com - every placement we could check was gone. A single platform's expiry policy can wipe an entire category of your effort.

The takeaway is not "avoid free links." It is "know which ones you are building." One classified site deleting everything is a rounding error if 90% of your program is profiles and articles - and a disaster if it was your whole plan.

What this means for your SaaS link strategy

1. Free links are a legitimate foundation, not a waste. The durability data supports what we already argue: build the foundational layer early. It sticks.
2. Weight toward profiles and articles. They survive, they carry your brand, and they are the same placements that build entity trust for AI answers. Treat forum and classified links as bonus, not backbone.
3. Don't confuse "live" with "working." Survival is the floor. A living link still needs to be indexed to count and to sit on a page with real authority. Use this study for durability, not value.
4. Monitor what you build. A 7-12% removal rate over a quarter means link rot is real at the margins. A simple backlink monitoring system catches the losses so you can replace them.

The limits of this study (stated plainly)

• It measures survival, not value. We did not measure whether each live link is dofollow, indexed, or on a trafficked page. Those are separate questions; do not read "87.9% live" as "87.9% valuable."
• The blocked bucket is real. 37.4% of URLs could not be verified. The survival rate is honest about its denominator - 2,281 conclusive cases - but a different sample might land a few points either way.
• One operator, one time window. This is our data, our placements, Feb-Apr to July 2026. It is a large first-party sample, not a universal law. We are publishing the method so it can be checked and repeated.
