Do startup directory links help SEO? Nofollow, ugc and sponsored explained

A link from a startup directory is a small, real signal at best and a liability at worst. Which one you get depends on two things: the rel attribute on the link, and whether the directory is a place people actually use. This guide explains both, using Google's own documentation, so you can judge any directory before you submit.

The short answer

A directory link does not make a new product rank. It can help Google find your site, it can send visitors who are looking for tools like yours, and a plain link from a directory with real editorial standards is an ordinary citation. A link from a directory that exists to sell links is treated by Google as link spam.

If you remember one thing, make it this: judge a directory by whether it sends people, not by the attribute on its links.

What the rel attribute says

Google's guide to qualifying outbound links (last updated 10 December 2025) describes three values a site can put on a link:

• rel="sponsored" marks advertisements and paid placements. Google says nofollow was the older advice for these and is still acceptable, but sponsored is preferred.
• rel="ugc" marks user-generated content such as comments and forum posts.
• rel="nofollow" is for the cases the other two do not cover, when a site does not want to be associated with the page it links to.

Google says links with these attributes will generally not be followed, and that the linked page may still be crawled if Google finds it another way, such as a sitemap or a link elsewhere. In practice, treat the attributes as signals, not as switches that guarantee an outcome either way.

A link with none of these values is a plain link. You will see directories call this a "dofollow" link. HTML has no dofollow value for rel; the word only means the link has no qualifier.

Which directory links count as link spam

Google's spam policies (last updated 28 August 2026) list two practices that matter here:

• Buying or selling links for ranking purposes. Google adds that paid links are fine when they carry rel="nofollow" or rel="sponsored".
• Low-quality directory or bookmark site links.

The second one gives you the clearest test: if a directory exists mainly to hold links rather than to be read, a link from it does little for you and can put your site next to pages Google already distrusts.

What a listing link can do for you

A good directory listing does three useful things, none of which depend on the rel attribute:

1. Discovery. A crawlable page that links to your site is one more path for search engines to find it, which matters most in the first weeks when nothing else links to you.
2. Referral visitors. People browsing a category or a weekly board are often looking for exactly the kind of tool you built. They arrive already looking for a tool like yours.
3. A page about you that others can find. A listing with a clear description, screenshots and pricing can rank for your product's name, and it gives writers a neutral page to cite.

A plain link from a directory that edits what it publishes is also a normal citation, the same as any other site writing about you. That is a modest signal, not a ranking plan.

How to judge a directory before you submit

Check these before you spend time on a listing:

• Are paid placements labelled? Every paid slot should say so in text. If paid listings look identical to organic ones, the directory is selling position.
• Does it publish a ranking method? If the order of products is not explained, assume money or the operator's taste decides it.
• Does it show traffic it sent? A directory that counts outbound clicks can tell you how many visitors it sent. One that does not count them cannot tell you either.
• Does it reject things? A directory that publishes every submission, including obvious spam, is the low-quality case in Google's policy.
• Would you browse it yourself? If you would not look for a tool there, your customers will not either.

How this directory handles links

On What’s New Today the link rules for every kind of listing are published on How we verify:

• Paid placements are labelled in text and never take a numbered place. Money is never an input to rank; the formula is on How we rank.
• Links in maker updates carry rel="ugc nofollow", since they are user-written.

None of this is a promise about your rankings. What Google does with any link is Google's call.

What to do instead of chasing links

Spend the time a link-building spree would take on things that compound:

• Write the listing well enough that a stranger understands the product in one read. Our guide on writing a product listing covers this.
• List in a few places where your buyers already look, and skip the hundreds of submit-only directories.
• Check which places sent visitors after a month, and keep updating the listings that did. Our guide on telling whether a directory sends real traffic shows how.

The listings worth having are the ones people click.
