Why is the site lowered below nowhere without keywords?

Question

Search Engine Optimization

Hello, please tell me, following the advice of many articles on the Internet, I removed the keywords from the site, highlighted them with the tags b, strong, em, h1, h2, etc., but now the site hangs At the very bottom among abandoned sites, somewhere in the 60th place and clicks from the search 40 pieces per day from Yandex and 30 pieces from Google, for queries where the name of the site itself, I thought it temporarily waited 3 months, the site became even lower, although it was without any SEO optimizations, with a bunch of errors in the validator (200 pieces on each page), and with a bunch of ads and scripts anywhere (20 pagespeed) - at 7-9th place, as soon as I fixed everything (speed, errors) and removed the keywords, the site went down, how could this affect? What can be done ?

Answer 1

Take it all back, isn't that the obvious answer?
And consult with experts first before you radically change something. Or do you, when you have a toothache, also go to read articles on the Internet instead of going to the doctor?

Answer 2

Keywords no longer provide a ranking advantage. The reason is not in them!

Answer 3

Return everything back, wait in the face of the one who advised

Answer 4

Yes, just return everything. Go to the Internet Archive . Pull out as it was. And you pour. But, unfortunately, the positions may not be fully restored.
And my experience says:
- Do not believe all the advice of CEOs in a row.
- The advice of a person with a successful website can be much more accurate and effective.
- Keep in mind that search engines love to spread fables.
