Site tracking panel (site panel / project panel) - which one is better to use?

Question

Search Engine Optimization

A free or extremely inexpensive panel of sites is required, many of the existing ones have been tested - I settled on PR-SU - but there are always inaccurate data * . Maybe you have more accurate services in mind?
ps
Well, if the service can monitor the unavailability of the entire resource at least a couple of times a week.
* - I've already been observing a year, then the TIC is not the same, then the number of pages, then the links ... I realize that this data can not always be truthfully collected, but still it's too nervous to see :) So nerves to hell with this SEO !

Answer 1

Ahem. Why are you not satisfied with Yandex Webmaster + Search Console that you are looking for alternatives?
You will hardly find more precise information than there. At least from the needs that you described, I don't know why you should look for something else.

Answer 2

Try this site panel
