I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
I back up my blogs using a plugin WP DB Backup. If anything happens I will restore my blog to the last settings. I use my blog to be scanned by WP Security Scan plugin frequently and WordPress Firewall to block suspicious-looking asks to fix malware problems free.
I protect an access to important files on the site's server by putting an index.html file in the particular directory, that hides the files out of public view.
First in line is currently creating a password to your account. Passwords must be made with numbers and characters. You can combine them and create plus shifted letters. Smarter reference passwords can be your gateway to zero hackers. Make difficult passwords that you can think of.
Now we're getting into things. Whenever you install WordPress, you have to edit the file config-sample.php and rename it to config.php. You want to install the database information there.
Implementing all the above will take less than an hour to complete, while making your WordPress website more resistant to intrusions. Over 1 million WordPress websites were cracked this past year, mainly due to easily preventable safety gaps. Have yourself prepared and you are likely to be on the safe side.
