Two tools, both genuinely useful

Built from the checks we run internally before a site goes on our own marketplace. Free, no email, and honest about what they cannot tell you.

What we did not build

We had an AI visibility checker here. It queried one model and estimated the other five while telling you it had checked six. Ahrefs gives away a better version that genuinely queries five, so there was no honest case for keeping ours.

Same reasoning for anchor text analysis and guest post finders. Both are covered by good free tools already, and building a worse copy to have something to link to is how a tools page stops being worth visiting.

Why these two

Publisher vetting is the one thing everyone tells you to do by hand and nobody automates. It is also what we do all day: every site on our marketplace went through these checks before it was listed, and roughly two thirds of what we assess never makes it.

The relevance checker answers the other half of the question. A site can pass every quality check and still be no use to your client, because it writes about something else. Every tool in this market sorts on domain rating; almost none help with whether a publisher is actually about your subject.

We considered an outreach email writer and dropped it. Every AI email generator templates whatever you type in, and a better one would still be a worse use of your time than knowing which sites to pitch in the first place.

Or use the list we already vetted

410 publishers that passed these checks, with prices, and nothing to pay until a link is live.
