"Web Designer"
A person that does the job of designing websites is called a web designer. This person is solely responsible for making the website look really nice and attractive with the latest trends and logos to attract customers. A web designer is different from a web developer so don't confuse them. A web developer is the one that builds the website from the inside using coding.
"Website Design Company"
Is where wed designers work and are in charge of making sure all its customers receive top quality service in their design packages.
"Web design Agency" is the term given to a company that designs and develops websites. 'design' is to make, layout and design a certain thing.
'develop' to build, plan and create a certain thing.
A web designer designs the website and the developer makes the actual website.
I googled this question for my area, and I found that a lot of the places that do this type of work call themselves a "studio", like they are a film or still photography studio. Some places called themselves a "firm" (like a company), and a smaller number used "company" or "agency". I don't think the web design industry has decided what is the correct name to call businesses that are involved in this work.
A company that makes websites would be: A website design company.
A person who makes websites would be: A website designer.
