You don't need SEO.
Unless you want to be seen!
Stumbled across this looking up info on different fruits and such on google.. easier to explain if I just show it to you:
So hopefully after resizing a few times you can still at least get the gist of it!
SEO is definitely important if you want to be seen online!
Every other fruit you search comes up with pictures of and info for the fruit or the color orange, but Apple, its just Apple... not much for the first page or two on google in the way of actual apples, just the company!
I think this little collage is enough to show how important SEO is for your online presence!
Good luck to all of you out there, I wish you the best!
Keep on keeping on!
