How we checked the link
For each directory we sampled three ordinary listings, found the link to the listed product, and read its rel attribute. A directory is on this list only when the standard free or paid listing carried no nofollow, ugc or sponsored hint on the day we checked. Google treats all three hints the same way, so a link with any of them passes nothing.
Where a directory follows the link only on a paid tier or once a badge is embedded, it is not on this list; its own page says what unlocks the followed link. Where the sampled listings disagreed, the directory is marked Mixed and left off too.
How to work this list
Top to bottom, free first. A followed link from a distinct domain is the one thing Domain Rating responds to, so ten of these from ten different sites is the fastest route from DR 0 to double digits. The ones near the top with DR 80+ are worth a listing fee if the free queue is long; the ones under DR 30 are worth a listing only if their audience is yours.
Do not resubmit to a directory that already lists you. Ahrefs counts a domain once. Two listings on the same site is one link.
What to expect
Directories change. Free tiers go nofollow, badges become required, sites die. Every directory here is re-checked on a schedule and the date at the top of this page is the last pass. Re-run your rank plan before a new round of submissions and it will mark the listings you have already completed.
