SEO technical concepts

SEO or Search Engine Optimization is the process of enhancing a website’s traffic by increasing its visibility (a.k.a impressions) on search engine results pages (SERP).

Constant optimizations on the content, site performance, usability, and link profile significantly improve your website’s search engine visibility.

No matter how excellent an online service is, it won’t pay off until you offer it to the right audience. 

A website listed on the 10th page of search results won’t stand a chance against its better-positioned competitors.

To evaluate a website’s technical health, you can use site audit tools such as PageSpeed Insights by Google, Lighthouse in Google Chrome’s Devtools, GTMetrix, and SEMRush.

These tools audit your site and tell you what’s already good, what could be better, and what has to be fixed.

FID, LCP, and CLS are known as Core Web Vitals
