Will JS Affect Your Page’s Loading Time?
JS websites require rendering by bots so they can be displayed. However, this process takes time. JS sites have higher loading times compared to pure HTML websites. However, with the use of the right tools, you can optimize your loading times.
Load events and user events can greatly affect SEO.
This is fired by the browser once the site is completely loaded. Bots take a snapshot of the rendered content immediately. Those that were not posted after the load event activates will not be crawled and indexed because JS site content quickly changes, especially for news pages and social feeds on sites like Twitter and Facebook.
More events can be triggered via JS after the load event. Common examples include “onClick-Events.” These are user-triggered, like site content restriction or interactive navigation. However, these are not usually indexed because they happen after the load event.
1. Indexable URLs
Your website needs a unique URL to be indexed. However, the pushState method that is created with JS does not generate a URL. You will need a server-side URL for every product presented in your JS website for them to be indexed.
2. pushState Errors
With the pushState method, URLs can be changed. The original URL should always be relayed to the server-side support to prevent duplicate content.
3. Missing Meta Data
You should always add a unique meta title and description for Google to identify whether your page is a good match for a search query.
4. HREF and SRC
Google requires links that it can follow to find more sites. You must always have links with href or src attributes in your documents.
5. Create Access for All Bots
As discussed above, not all bots can handle JS. Adding a title, meta description, and social tags in the HTML code may help.
6. Never Restrict JS Over Robots.txt
7. Use a Current Sitemap
To show Google any possible changes in your JS content, keep the attribute “lastmod” updated in your XML sitemap.
