Okay, so I'm wandering around on different 'how to' freelancer sites and I've read a few times that WordPress is important to freelancers. I searched here first, before posting this. I have a wordpress site that I use for my adult blogs and such, but I don't understand if installing word press is important to freelancers and why? I didnt' set up the word press site, my boss did, so I'm a little clueless as to if I should have it on a freelancer site that I am building, and why I should have it?
There is no rule that says you have to use Wordpress for anything. But, if you are good at using Wordpress it could help you land more work and it could be useful for building your own website where you sell your freelancing services.
I have hired a lot of freelancers for a lot of different gigs over the years. Some of those gigs required the skill of knowing how to create Wordpress blogs or at least knowing how to publish on them. So some Wordpress experience was a prerequisite for hiring a freelancer in those situations. If you have zero experience with Wordpress then I would not have even considered you for those gigs.
Now, that is just one example. However, Wordpress has become so popular that you are going to see Wordpress experience being a prerequisite for a lot of jobs that are offered on places like Upwork. In fact, when hiring writers, a lot of employers will assume you know how to publish articles on Wordpress and do basic things like embed images, change titles and Alt tags, fill in the SEO fields for plugins like Yoast SEO for Wordpress, etc. Those things are becoming very common.
When employers look for a USA based freelancer, they are generally looking for a freelancer with a better skill set who is a little more talented than average. If they didn't want that increased skill set and increased mastery of the English language, then many of them would just hire from outside the USA for a lot less money. So being a freelancer based in the USA makes it even more important to upgrade your resume as much as possible.
