How much JavaScript can affect my site's SEO?
« on: 07-03-2020, 00:00:36 »
I have heard John Mu & Martin Splitt from Google speak about Googlebot indexing in two waves - first for plain HTML & then rendering the content (executing JavaScript). Keeping this in mind:

- If my text or images load via JavaScript & not through plain HTML - is that content on page less probable to be indexed?
- How does this play out considering every site has a certain Crawl Budget?

Looking for experiences, thoughts & opinion on this.

Hi,

Javascript sites aren’t bad for indexation but they make Google work harder. Google renders javascript sites more slowly. Hence you will face competitive disadvantage in SERP.

Long story short, JavaScript can complicate the search engines' ability to read your page, leaving room for error, which could be detrimental for SEO. When a search engine downloads a web document and starts analyzing it, the first thing it does is understand the document type

Crawlability: a web crawler's capacity to explore your website page by page. JavaScript can restrict which content a web crawler can discover. On the off chance that the crawler can't locate your substance, it can't record it.

The little things can hurt or help your search engine optimization (SEO). Web pages built with JavaScript, which is a computer programming language commonly used to create dynamic content such as video. When I use a search engine to look for a business’s web page and am having trouble finding pages that are easily navigated to on the site, one of the first questions I ask is whether the page or certain elements were designed with JavaScript. JavaScript can be a powerful tool for creating dynamic content, but there are downsides to using this programming language.

JavaScript can affect two specific issues:

Crawlability: a web crawler’s ability to navigate your site page by page. JavaScript can limit which content a web crawler is able to find. If the crawler can’t find your content, it can’t index it.

Obtainability: a web crawler reads your page but cannot figure out what the content pertains to. If the crawler can’t figure out what your content is, it can’t rank it for relevant keywords.
