SEO or Search Engine Optimization increases the quality and quantity of website traffic, increasing visibility of the website to users.
My first experience in handling SEO project was in WordPress using Yoast SEO.
I find it easy to work in since Yoast SEO has already listed the rules or guidelines in improving and boosting the score from Needs Improvement (Red) to OK (Orange) to Good (Green).
These are screenshots from a previous client of mine who assigned me to boost SEO scores of the articles and listings in the website. As an added bonus, I also improved the readability scores.
