Hello, I uploaded a website about a month and a half ago, and only 30% of the pages on the website have been indexed by Google. These aren't even the most important pages of the site. Could the issue be with the content of the site in question? Here is the website. In terms of performance on PageSpeed Insights, the score is good though (evereything is green) i don't undrestand What should I do to get Google to index all the other pages/articles? Thanks in advance
Nowaday Google consider on many factors and so, no one can suggest you without check your website. I will presonally recommend you to check Google search console to know all reason, at GSC you can see all details in PAGES section that how many pages are indexed, how many discovered but not indexed etc.. Generally if your page containing duplicate content or contents are not informative or contents structure are available online already (Can be rewriting issue) etc. then bots will not give you priority. Let us know your website URL to check and give you more details.
You should obtain the incoming links. Either buy them, or place them by yourself (guest posting, and so on) on the suitable sites, or make your site so useful for the public, that the people by themselves will place the links to your site on the other sites.
I would recommend investigating your non-indexed pages by using Google Search Console. Typically if there is a problem indexing a page it will show up in the console and provide you with a pretty good idea of what the issue is and where/how to fix it. A quick google search of the error message will also help you hone in on the problem. You can also resubmit the page for indexing instead of waiting for the crawler to find it immediately or after any fixes or updates are made. Hope that helps!
GSC google search console is your go to. Look at the feedback there. It'll tell you if your sitemap is any good, if your pages are indexed and what any problems might be. Google prioritises mobile performance so it needs to be at 100%. You might find it gives suggestions of things to change - you need to act on them.
Ensure your articles are high-quality, unique, and valuable to readers. Google tends to prioritize well-crafted content. Build backlinks from reputable websites to your important pages. These links can encourage Google to crawl and index your content faster.
