Most people probably don’t need to be told this as a blog is usually updated pretty regularly. However, it happens sometimes that you may have several blogs or you just created a WordPress site and figured that once it was up and running that you didn’t need to do anything with it anymore. This is not a good idea. You should log into your blog at least every week to get the latest updates to WordPress, plugins, and themes. If you don’t, you risk leaving your blog unprotected from the latest security exploits and it is only a matter of time before your blog is hacked and some changes are made that you don’t want made. Hackers will often insert code into your site that will present users with pop-ups or redirect them to sites they don’t want to be on. Sometimes they even infect the user’s computer and do the same things there. When Google and other search engines try to update their index and crawl your site then will see the infections and start telling people not to visit your site. This lowers your traffic and hurts your PageRank and your site’s reputation. Your position in searches will go way down as it is no longer a very friendly site to visit.
There are a couple things you can do to prevent this from happening while you are away. You can install the WordFence plugin and have your site scanned on a regular basis. You can install many different plugins to backup your blog so that it is easier to fix if you are hacked. I’ve heard good things about BackupBuddy (paid) but I personally use the free WordPress Backup to Dropbox plugin. I’m just cheap. I know how to restore and modify databases and re-upload my files. If you aren’t a very adventurous computer user you may have more peace of mind with BackupBuddy as it makes the whole backup and restore process very simple.
To close, you should check in with your WordPress site frequently just because the web is not static. Things change and you need to change with them. This is really true for just about any site in general. As an added bonus, if you maintain your blog or site on a regular basis you will be rewarded with higher search rankings and higher traffic. Search engines love sites that are constantly staying fresh and relevant.
