I have prepared a SEO glossary with a breakdown of terms that I use on a daily basis. I’ve realized that I live with so much technicality that I take it for granted that everyone knows what rare acronyms like CTR, WPO or even SEO mean.

But of course, when I start talking people look at me funny and it’s at that moment when I have to say “hey, if you don’t follow me tell me and I’ll explain you anything”, to which they answer “well start from the beginning, because you’re talking to me in Latin!”

Who is the SEO glossary for?

As I said, this SEO glossary is intended to introduce you to the terminology and technicalities that I use on a daily basis and techniques that I apply in my projects. Both blog and ecommerce users, webmasters and those who are starting in the SEO world will welcome this guide of rare words.

Uses of the SEO glossary

Of course, understanding all the terminology and jargon that we have in SEO will be of great help to webmasters and clients to be able to perfectly apply the SEO techniques indicated in a report, for example.

This SEO glossary will also greatly enrich developers and future SEO professionals when they learn new terms or discover that some techniques they already use have a name. Believe me, there have been times when I have been told about a particular strange term and when it was explained to me I said “but I have been doing that since prehistoric times!

I hope you enjoy this guide!
