disavow links tool to devalue the remaining links from harming the site. Apart

keywords per web page does not works any more. You can have 10-15 keywords or
even more to target on a single web page.

between soft 404 and 404 errors? How will you find and remove these errors?

not exist on the server. Hence, in both the cases, file is not present on the
server but in case of soft 404 the server returns 200 OK response code by

and we can either remove them by adding proper redirects and by creating a
