Despite popular belief, Google can read JavaScript

1 comment

SEOs have long stressed to their clients to use plain text as search engines can have difficulty reading JavaScript. This may have been true a few years ago, but Google has been making great strides. Adam Audette and his colleagues at Merkle recently put Google to the test and got surprising results.

They tested Googlebot in its ability to read JavaScript redirects, links, dynamic content, meta data and "nofollow." Googlebot was successful on all fronts. You can see their whole write up here: http://www.rimmkaufman.com/blog/google-crawling-javascript/13052015/

So what does this mean? Well, now there is a lot more that webmasters can do for the structure and appearance of their websites without worrying about whether their markup will be "counted." Of course, there are right and wrong ways to utilize JavaScript. Sometimes webmasters will use JavaScript to hide content and that is still highly discouraged.

People use AJAX / Angular ,etc for that now

I think the next thing that google is struggling with is handing ajax, they dumped their original guidelines (see links below) for it around last month, all of those new ajax frameworks are SOO not elegant from an SEO standpoint...
