Sometimes it’s interesting to take a look at who builds what and how competitors rank in competitive niches. There are 3 tools in total, but currently I use just one.
Publicwww.com
The most famous of all. You enter a domain in the format «domain.com», then enter a keyword, and export a list of domains. This is the one I use.
linxact.com
Not significantly more domains compared to publicwww.com. The functionality is a bit raw.
The price of $15/month is generally good.
Octohydra.io
A powerful tool for pros. It’s very expensive — $6,000/year. Octohydra seems to be like the Ahrefs of hidden links, but only for the chosen few.
Dataforseo.com
I accidentally noticed on my site that this crawler was visiting me, so I decided to check what kind of bot it was.
It exports via API, and I haven’t figured out yet how to make it digestible right away like in Ahrefs. I don’t really need the API itself that much.
