I have had two WordPress blogs. That was at a time when I was doing almost no internet marketing, and until I found time to handle the situation (weeks later), these sites were penalized at the main search engines. They weren't eliminated the ratings were reduced.
In addition to the graphics and text you're creating, you're going to require a backup and protection option for your new site. fix malware problem is very important, and if you don't protect and back up your website you could lose important data and information that might be tough to restore. You don't want to need to start over from scratch once you have done all that work, so be sure you're secure.
Backup plug-ins is also important. You need to backup all the database and files so in case of a sudden attack, you can easily bring back your own blog like nothing happened.
Yes, you need to do regular backups of your site. I recommend at least a weekly database backup and a monthly "full" backup. More, if possible. Definitely more, if you make additions and changes to your website. If you make changes multiple times every day, or have a community of people that are in you can look here there all the time, a backup should be a minimum.
Now we are getting into matters. Whenever you install WordPress, you need to edit the file config-sample.php and rename it to config.php. You want to install the database information there.
Utilizing a plugin for WordPress security just makes sense. Backups will need to be performed on a regular basis. Do not become a victim of not being proactive about your 16, as a result!
