I know WordPress seems to be the most commonly used, however it seems kind of tricky and sluggish to use in its back office area. Blogger seems to be more user-friendly, but not as customizable. Weebly seems super easy to use and customizable, but perhaps a little basic (unless paid) and perhaps not as prominent.
Will it make any difference to the search engines which one I use (this is prob my most important question)? Do I have to install various plugins for SEO or pinging or submitting to directories, or edit HTML to make sure keywords are listed properly or "meta tagged" (?) or whatever, etc etc?
Essentially I'm looking to create a blog (or a perhaps a website and a "/blog" page) where I can upload content each day in my niche, so it's important that it looks professional and has all the right technical/background components correct so I can get ranked and liked etc. I'd also like to be able to customize it easily (eg add a lead capture box, social media buttons, video content etc) without paying web designers or buying a pricey editing program, so the more "drag n drop" it is, the better.
I know a bit about writing good copy, but not necessarily the technical bits-n-pieces of creating a blog/website, so I don't wanna use the wrong platform or miss something little-but-important that would make a big difference to maximizing my website's potential.
Any advice and recommendations of what to use and why, is most welcome and appreciated. Thanks in advance.
