I’m sure you would’ve come across at least a dozen of them lately. I try every SEO tool I find on the way. But let me honest with you, most of them are either broken or simply don’t work because either the API doesn’t allow to or the codes are wrong. There are hundreds of SEO tools around and I personally keep an exclusive bookmark of them, so that I can check back often. I think it has come to a point that I can share it with you now, hope they help you.

And yes, almost all of them are tried and experimented to check if they really work or not, so if there’s a broken SEO tool, you probably won’t see it here.

If you find any that are unworthy or listing here, please let me know and I’ll be glad to drop them.
