I've had two WordPress blogs. That was at a time when I was doing almost no internet advertising, and until I found time to deal with the situation (weeks later), these sites were penalized in the major search engines. They were not eliminated, no matter how the evaluations were reduced.
Besides the text and graphics you're creating, you're going to require a protection and backup option for your site. secure your wordpress website is important, and if you don't protect and back up your site you can lose important data and information which may be tough to restore. You don't want to have to start over from scratch once you have done all that work, so make sure you're secure.
Also, don't make the mistake of thinking that check this site out your hosting company will have your back so far as WordPress backups go. Not always. While they say they do, it has been my experience that the hosting company may or might not be doing backups. Take that kind of chance?
First in line is creating a password for your account. Passwords must be made with special characters and numbers. You may combine them and make small shifted letters. Smarter passwords can be your gateway to zero hackers. Make passwords that you can think of.
It's time to register for a Facebook accounts that is new and use this person's name and identity. After I get it all set up, I'll be emailing you posing as your friend and asking you to be friends with me on Facebook (or Twitter, or whichever social site).
Don't use wp_. That default is being eliminated by web hosting providers but if yours does not, adjust wp_ to anything but that.
