As an SEO analyst, I see JavaScript-related SEO issues fairly often. I particularly encounter many of these issues on modern websites where most of the content loads dynamically. The issue is that while the website may look perfectly fine for all the visitors, the search engines struggle a lot to process most parts of it.
On a recent project I was working on, a website based out of Dubai, I noticed that some important service content and internal links were being generated through JavaScript. Google eventually rendered some of the content, but certain pages were taking longer to get indexed, while some links were not being discovered as expected.
What I usually check first:
- Rendered vs. raw HTML: I compare what is available in the initial HTML with what appears after JavaScript runs.
- Google Search Console: The URL Inspection tool helps me see how Google actually renders and views a page.
- Internal links: I check whether important links are present in the rendered version and can be crawled.
- Indexing patterns: If several pages suddenly show indexing delays or disappear from search, JavaScript is one of the things I investigate.
The fix is not always to remove JavaScript. You must check all the other elements involved. I recommend moving important content, links, headings and metadata into the initial HTML. For heavily JavaScript-dependent websites, server-side rendering or static generation can also help.
For businesses in Dubai, this matters quite a lot. Competition is intense, and having a polished website is only half the job. If Google cannot properly understand or access the content, a technically impressive website can still lose valuable organic visibility.
To conclude, JavaScript should help the website work better, not become a barrier between your content and Google.
