Mueller is constructing a private web site that requires redirects, and the one manner he can implement them in Hugo is with JavaScript.

He then asks Splitt, Google’s resident JavaScript knowledgeable, whether or not there’s any purpose to be apprehensive about utilizing JS.

“No, you don’t have to be worried about that…

A question that I often also get with JavaScript is if we treat JavaScript content differently. We do have annotations for content– what we think is the centerpiece of an article or what we think is content on the side and stuff.

But as far as I know, and as far as I can see, we crawl a page and then put the content into the document in our index, and then we render the page, and then we complete the content from the DOM.

That’s it. There’s nothing that is fundamentally different between JavaScript generated content and static content, except for when there’s edge cases, and we can’t see content that is generated by JavaScript.”

That’s an issue, so far as search engine optimisation is worried, as a result of Googlebot doesn’t work together with something when it crawls webpages.

If content material is hidden behind a JavaScript factor that customers have to click on or faucet on, Google merely received’t see it. Therefore the content material can’t be used to perceive the web page and rank it in search.

Site homeowners who intend to use JavaScript on this manner as a design alternative ought to make sure that the hidden content material isn’t essential to understanding what the web page is about.
