After fixing technical SEO issues—such as indexing problems—and optimizing internal links, how long did it take for you to see changes in rankings after Google re-crawled the site?

For most sites, the first changes appear within 2–4 weeks after Google re-crawls the updated pages. Larger sites can take a couple of months. It really depends on crawl frequency, competition, and how serious the technical issues were.

1. Internal linking!!
2. Sitemap.xml correct
3. Redirect for e.g. www. to non www
4. Canonicals

I am working on improving the technical SEO of my website, but there are so many things to focus on that it’s difficult to know what should be the priority.
I have seen recommendations about site speed, indexing issues, Core Web Vitals, internal structure, and other technical improvements.
I would like to know from your experience which technical SEO changes made the biggest impact on your website’s rankings or overall performance?

Hey bro,

From my experience, the biggest technical fixes that actually moved things were:

1. **Site speed** – especially mobile. Making the site load faster helped both rankings and user behavior.
2. **Indexing issues** – fixing pages that weren’t getting indexed properly (or were blocked by mistake) made a clear difference.
3. **Core Web Vitals** – improving LCP and CLS helped, but only after the basic speed was fixed.

Internal linking structure also helped a lot over time, but it didn’t give a sudden jump.

Many try to fix everything at once. Nothing against that, but I found that it's better to check the Search Console first, fix the biggest problems (e.g., crawl errors, indexing, speed), and then move to the smaller stuff.

Indexed pages are very important and also the internal linking and structure will be best to optimize. Also updating and posting content constant is a must to get best results
