Question

Search Engine Optimization

Good afternoon, I used the Screamingfrog crawler and it gave me these links with a 404 error.

The following questions arose.
1. How can I find out if they are in the index or not.
2. How to properly remove them from the site.
3. Or it's okay and leave it as it is.

Answer 1

1. How can I find out if they are in the index or not.

1. by viewing the data on the pages in the index in Yandex Webmaster 's office - Indexing - check the status

2. How to properly remove them from the site.

most likely, if you delete them, the phone number will no longer be clickable

3. Or it's okay and leave it as it is.

Try to format the link like this:
[phone]
where, rel="nofollow" - tells the robots that the hyperlink does not need to be crawled.
