Is it necessary and how to put Noindex on Wordpress?

Question

Search Engine Optimization

A car service site on Wordpress, the site is no longer a young page, ranking well in Z and G. Avada theme (if that matters). The site has about 200 pages for each car model with unique content. There was a need to add the same
text to all pages with cars (about 5 sentences with 2 pictures) with a description of the benefits of our service. It is natural to rewrite it for 200 pages, and it makes sense. Question 1 : what is the probability that this piece of text will spoil the position in the organic? Question 2 : how to enclose this text in Noindex (or whatever it is called for search engines) in the Wordpress text editor? Question 3 : is it the same tag for Google and Yandex?

Answer 1

1. There is a chance of deterioration, but not a big one, because search engines understand that this is conditionally your USP and it can be repeated on many pages.
2. I think not, because it, in my experience, already does not work as we would like, for example, the "Baden-Baden" (host) filter cannot be removed by enclosing the text in a noindex. Although if, nevertheless, the positions decrease in Yandex, try it.
3. No, the noindex tag only works in Yandex.

Answer 2

Counter question: why not hide a block of text with JavaScript or AJAX?
The essence of this method is that the content itself is in an external file and is loaded after the document is loaded. In this case, search engines cannot index it. To hide the text from search engines, we create an html file with the content that needs to be hidden. Do not forget to close files with the script and text that we want to hide in robots.txt from indexing.
