ahrefs.com
The best analysis service, there are no alternatives. What’s its key feature?
The fact that you can filter and find GOOD links.
What does that mean?
In the screenshot, we see 5k domains:
And if you look at actual links, there are only 500 using this filter — 10 times fewer.
A good link is:
— dofollow
— DR > 10
— no more than 100 external links from the page
— links to an HTML page
Here is the Ahrefs filter itself.
I also implement GOOD links on my PBNs.
majestic.com
The oldest service of all. I use it for Netpeak Checker API checks. I check TF, CF, and domain count.
moz.com
The third service. I don’t use anything else) I also only use Moz via API. The DA metric is interesting. The service itself is ancient, of course, and has fallen behind in development.
