Directory sellers pitch the same thing: a "dofollow backlink" from a high-authority site. Whether it is worth anything depends on three details most pitches skip: how the link is tagged, what Google says about links that are paid for, and whether the directory's pages carry the tag its sales page promises.

This guide covers all three, using Google's own documentation and a check of 97 directories and launch sites that we ran on October 10, 2026. The short version:

A plain link is what people call dofollow. Links tagged nofollow, sponsored or ugc are hints to Google that the page does not vouch for the target, and in most cases they carry no ranking credit.
Google's spam policy treats exchanging money for links as link spam unless the link is qualified. Paying for a listing is fine; paying for a followed link is the problem.
Half of the 97 places we checked served a plain link and a third tagged it. Of the 23 that promise a followed link, 5 served a tagged one on the pages we read; for four of the five we could not tell whether those listings were paid ones.
A listing without a followed link still earns clicks, a page that can rank for your name, and a consistent description. That is what to pay for.

The link tags, and what "dofollow" means

Google's guidance on qualifying outbound links, last updated in December 2025, describes three values of the rel attribute on a link:

Tag on the link	What it tells Google	Used for
None	An ordinary link: the page vouches for the target	Editorial links. People call this "dofollow"
`rel="nofollow"`	The page does not want to imply endorsement or pass ranking credit	Links the publisher does not vouch for; still accepted for paid links
`rel="sponsored"`	The link is part of an ad, sponsorship or other compensation	Paid placements; Google's preferred tag for them
`rel="ugc"`	The link sits in user-generated content	Comments and forum posts

Three details cause most of the confusion.

"Dofollow" is not an HTML value. A link without a restrictive tag is followed by default. Some sites write rel="dofollow" anyway; no standard defines it, so the link behaves like an untagged one.
noopener and noreferrer are not ranking tags. They concern browser security and referrer data. A link with rel="noopener" is still a plain link.
All three tags are hints, not commands. Google said so in September 2019, and said it would generally keep treating nofollow and user-generated links as it had before: not for ranking.

What Google says about paid and traded links

Google's spam policies, updated August 28, 2026, list "Exchanging money for links, or posts that contain links" first among their examples of buying or selling links for ranking. The list goes on: exchanging goods or services for links, services that create links automatically, low-quality directory links, and requiring a link as a condition of a terms-of-service or similar arrangement without letting the other site qualify it.

The policy does not ban the transaction. It says buying and selling links is a normal part of the web, and that having such links is not a violation as long as they are qualified with nofollow or sponsored. A site that breaks the policies, it adds, may rank lower or not appear at all.

So the line runs through the tag. A directory that charges for a listing and tags your link nofollow or sponsored is inside the rules. A directory that charges for a listing and promises a followed link is selling what the policy names.

Why a paid dofollow link is a risk, not a feature

Followed links are the product because they are what moves Domain Rating, the number in most sales pitches. Ahrefs, which publishes DR, says nofollowed links do not raise it. A seller that guarantees a DR increase is therefore guaranteeing followed links; we compare ten services that sell this in AI directory submission services.

Three reasons to treat that as a liability:

It is the arrangement the policy names, and the policy covers buying as well as selling.
The payoff cannot be measured. Nobody outside Google can say whether a given followed link counts, is ignored, or counts against you. A commenter on an April 2026 r/SaaS thread about There's An AI For That never saw the backlinks from a few listings in Google Search Console or Bing. The upside is unknowable; the stated downside is lower rankings.
Sellers do not always deliver it. See the next section.

Free tiers raise the same question from the other side. Dang requires a crawlable backlink to Dang for its free tier, Fazier requires one on your homepage or footer, and TinyLaunch grants its dofollow link when you embed its badge. Each is a listing traded for a link. We do the same on our free path, as the last section says.

What 97 directories say, and what they serve

Our research pass on October 10, 2026 covered 97 live places: 53 AI directories, and 44 launch platforms, startup directories, review sites and communities. For each we opened a handful of listing pages, one to twenty, mostly picked by hand rather than at random, and read the rel attribute on the link to the listed product. We call a link with no nofollow, sponsored or ugc a plain link. We read 76 sites live that day. For 17, mostly sites behind bot checks, we read dated copies from the Internet Archive, the oldest from June 2025. Seven gave nothing to read: four we could not open at all, and three (Capterra, GetApp and TrustRadius) showed no readable vendor link on the pages we could see.

The table sets what each site says about its links, on its submit or pricing page, against what its listings carried.

What the site says about its links	Places	Plain link	Tagged nofollow, sponsored or ugc	Own redirect, no tag	Nothing to read
Promises a followed link	23	17	5	1	0
Depends on plan, votes or badge	14	7	6	0	1
Says its links are nofollow	2	0	1	0	1
Says nothing	58	26	20	7	5
All	97	50	32	8	7

A plain link is the most common result, 50 of 97. But 32 places tag the link, 16 of the 53 AI directories and 16 of the 44 launch and startup sites, and 8 send the click through their own address. One listing is not a policy, though. Free and paid listings can differ (DevHunt's FAQ says free listings are nofollow and paid launches dofollow), and so can old and new ones.

Where the promise and the markup disagree

PitchWall is the clean case. Its submit page lists a "Do-follow backlink (DR 70)" on all three plans, the free one included. In a random sample of 20 product pages from its sitemap on October 10, 17 had an outbound link, and all 17 went through its own /out/ address with rel="noopener nofollow".
FindMyAITool, Aidirs, The Next AI and Tooldirectory.ai all promise a followed link, the first three on every plan they list and Tooldirectory.ai on its paid ones. The listings we sampled carried nofollow or sponsored. We could not tell whether those listings were sold ones, since a directory can list a product its maker never paid for, so these are open questions, not proven broken promises.
Toolify promises at least six followed links for $99. In the Internet Archive's copy of January 9, 2026, its main buttons carry rel="dofollow" and its alternatives list carries nofollow.
Plan-dependent promises are the hardest to check. EarlyHunt's pricing page says free launches get nofollow links by default. The five project pages in our pass had plain links; a random sample of 30 from its sitemap on October 10 had 28 nofollow and 2 without a readable link. At Uneed, which ties its followed link to an upvote score, 6 of 23 pages we sampled were nofollow, all with fewer than 10 upvotes. The pages a researcher opens first are not a random sample, and the markup does not say which plan a listing is on.
An outside check agrees. Stork's October 2026 teardown read listing pages at six directories that advertise dofollow and found two, Turbo0 and Good AI Tools, serving rel="nofollow". Stork is a directory too, with its own interest, but the method is public.

Redirects

Eight places send the visit button through their own address. What that does depends on the redirect. Future Tools uses a /go/ address that returns a 302 and is disallowed in its robots.txt, and Dang's short link returns a 302 with an X-Robots-Tag: none header. BetaList's FAQ says its 301 passes link equity. In each case the anchor has no tag; what Google does with the redirect is a separate question.

The big names

Directory	What we read on its listings
There's An AI For That	Plain link on the main button, nofollow in alternatives lists, sponsored on spotlights (archive copy, March 28, 2026)
Futurepedia	`nofollow` (live)
Toolify	`rel="dofollow"` on main buttons (archive copy, January 9, 2026)
TopAI.tools	`nofollow` (archive copy, October 5, 2026)
AIxploria	Says all outbound links are nofollow, and they are, via its `/out/` address (live)
Dang	Own short link, 302, `X-Robots-Tag: none` (live)
Future Tools	Own `/go/` address, 302, disallowed in robots.txt (live)

What a listing earns without a followed link

Clicks. The founder reports in Are AI directories worth it? run from 75 organic clicks in a week to 312 in a day for paid listings, with about one click in six or seven becoming a sign-up.
A page about you that can rank. One founder said the real value of a There's An AI For That listing was that the page ranked for category searches. You can test this before paying: search the exact name of a product already listed and see whether the directory's page appears at all.
A signal, not zero. Because tagged links are hints, Google can still use them to understand what a page is about.
A consistent description. A commenter in an August 2026 r/SaaS thread argued that when enough places describe you the same way, an AI assistant repeats it. That is one founder's view, not something we have measured.

What it does not earn is Domain Rating. Whether you should care is another matter: Ahrefs itself advises against using DR alone, since it measures link popularity, not a site's quality.

How to check a link tag yourself

Open a listing page, ideally for your product and for someone else's, since paid and free listings can differ.
Right-click the visit button and choose Inspect (in Safari, turn on the Develop menu first). The browser highlights the link's HTML.
Read the rel attribute. nofollow, sponsored or ugc means a tagged link. noopener and noreferrer do not count. No rel at all means a plain link.
Read the href. If it points at the directory itself, such as /go/, /out/ or /visit/, the click goes through a redirect. Look at its response headers and at the site's robots.txt. Repeat on three or four listings.

For step 4, two commands show what a redirect returns and what robots.txt blocks. Many directories block curl behind a bot check; the browser's Network tab shows the same headers.

curl -sI "https://directory.example/go/your-tool" | grep -i -E "^(HTTP|location|x-robots-tag)"
curl -s "https://directory.example/robots.txt" | grep -i disallow

Where EffectHub stands

Disclosure first: EffectHub is an AI directory, so we have a position. Links from our pages to tool sites are marked nofollow sponsored, and we do not sell followed links, rankings, scores or a Verified mark. A listing is free while our badge, an image that links to your page in our catalog, is on your site. Without the badge it is $24, reviewed within 48 hours of payment, with a reason whenever the answer is no. Submit a tool.

Questions people ask

Do nofollow links help SEO at all?

Rarely as ranking credit. Google treats them as hints and, in most cases, does not count them for ranking; Ahrefs does not count them toward DR. Their value is the click and the page that mentions you.

Is it against Google's rules to pay for a directory listing?

No. Google says buying and selling links is a normal part of the web, as long as the links are qualified with nofollow or sponsored. The violation is a followed link exchanged for money, goods or services.

Does a high-DR directory mean a better link?

Not necessarily. DR scores a site's link profile, not its audience. Stork's teardown found 7 of the 27 directories it measured outside the Tranco top million sites, four of them at DR 66 to 74, and 28 of our 53 live AI directories are not in that list either.
