33 Free SEO Tools for 2021

What is SEO

SEO (Search Engine Optimization) is the process of getting traffic from “organic” listings on search engines in order to improve your website’s search engine ranking.

It is about making sure that, when any person searches on a SE (Search Engine) with keywords related to your line of products or services, your website appears as high up as possible, hopefully on page 1, on the search engine results page (SERP).

SEO is a collection of strategies, techniques and tools used to increase the number of visitors to a website by getting placed high in the SERP — including Google, Bing, Yahoo and other search engines.
