Preventing Comment Spam.
If you have been a blogger you are sure to have been a victim of comment spam. If you are one of the lucky few that don’t know what comment spam is I will give you a brief explanation. Comment spam also known as blog spam is a form of spamdexing. It is the practice of deliberately creating web pages which will be indexed by search engines in order to increase the chance of websites or page being placed close to the beginning of search engine results.
Google has tired to solve some of this spam indexing by allowing the rel= “nofollow” to be added to a link which in turn is ignored by the Googles index. This tag tells the search engines not to follow any of the hyperlinks in the body of the document.
Method 1:– Delete each and every post.
This option many not be the easiest way to handle comment spam if you are receiving 500 comments or more a day.
Method 2:– Use Plugins or scripts.
There are a few plugins available that will catch the spam for you before it is posted. The most popular plug-in is Akismet. Akismet is truly a lifesaver for some bloggers. Akismet is a very easy plugin to use and for WordPress blogs it is already a plugin application installed in the software. Other weblog software can use Akismet as well. You can visit the development page to find out if a plugin is available for your blog software. Once Akismet catches the comment spam it holds the comments for 15 days before deleting. Occasionally the plugin with put real comments in the spam category so be sure to check your Akismet spam section regularly.
