What online SEO services do you use for your websites?

Question

Search Engine Optimization

What online SEO services do you use to easily check your site for broken links, for the presence of any robots.txt and sitemap.xml, for the presence of h1 on the pages, page loading speed, recommendations, etc.
There are many such services, but either one or the other: either registration is needed, or it’s not free, or it checks one thing ....

Answer 1

In general, most of all the good that others have for a fee is in Google Webmaster: broken links, incoming links, sitemaps with robots, etc. Moreover, since this is Google - the reliability of the data here is 100%, so to speak, firsthand!
In general, in view of the fact that the site is mine, you can spend some money on a paid service account, which represents everything that is not in Google Webmaster.
For example, I use seranking. Very pleased with them. For $20 +, having connected yand.-xml, I have been using it for more than a year to check positions for ~ 150 requests, with a frequency of 2-3 times a week, and its other services, without saving much and another ~ $ 5 left on the balance!
If from ball ones then: pr-cy.ru, pageSpeedInsight, mobileFriendly Google, w3c validator.
It seems to be everything. Enough with the head, so as not to remain in the "suckers")))

Answer 2

Everything depends on the tasks. For the most part: Ahrefs, SEMrush, Majestic, Search Console, Google Analytics.

Of the free ones, I like the title parser, TopAnalyzer and coolakov.ru/tools I shoot
positions at https://spyserp.com/ru/ I have been using it for several months, while I am satisfied. Spiserp has a free plan with good limits.
