I’m adding a rel=nofollow attribute to links via jQuery after the page load.
Will Google see this attribute? I can’t find anything in Google’s official documentation.

  1. The Google spider does process Javascript, so adding the attribute via jQuery should work. I would suggest that you put the rel="nofollow" logic in your server-side code though, for guaranteed results.

    In short, No!, that link is already been crawled with google spider.

    rel=nofollow this attribute should only work if you have set it at serverside when a request is made or you should put it static via keyboard, because after page load it doesn’t matter.

  3. Although Google processes JavaScript and can index a lot of dynamic content, there’s a special behavior when inserting rel=nofollow dynamically. It was tested[1] and they came up with this result:

    The nofollow in the DOM did not work (the link was followed, and the page indexed). Why? Because the modification of the a href element in the DOM happened too late: Google already crawled the link and queued the URL before it executed the JavaScript function that adds the rel=“nofollow” tag.

    The solution is to insert the whole link with rel=nofollow dynamically:

    However, if the entire a href element with nofollow is inserted in the DOM, the nofollow is seen at the same time as the link (and its URL) and is therefore respected.

    See section "5. An Important Example with rel=”nofollow”" of the provided source.
