Search engines need a steady flow of comments. Most blogs that appear in a web search have a post that has been published within the last few hours. Dozens of blog search engines operate for the sole purpose of alerting the big five search engines of new content. The posts that you publish on Saturday are already out of the lists by Sunday afternoon. That is why it is important to provide the search engines with fresh content daily.

A steady stream of content is so important that some blog software programs have a delayed publishing plug-in. This lets the blogger upload multiple articles at one time, but it waits until a pre-determined time to publish each one. This is a great idea, but it is only half the solution.

The blog search engines must be pinged shortly after the blog is posted. There are several good pinging services on the web. Most of them ping a few dozen blog search engines, telling them that your blog has new content.

This confuses most bloggers. They believe that tagging an article with a blog search engine like Technorati or Del.icio.us is all they need to do. Tagging is a method of introducing a list of your articles to potential readers. Tagging has nothing to do with building in-bound links or a web pages rank. Tagging is for peoples benefits. Pinging is for the benefit of search engines.

Publishing one blog a day and then pinging the blog search engines will ensure that the big five search engines never forget your blog. www.weblogs.com gives a visual of how blog pinging works. Each of the blog posts that appear on the page have pinged the blog search engines.

An overly simplified method of explaining pinging is by comparing it to crawling a webpage. Instead of waiting for a robot to crawl the blog, ping the search engine while the news is still fresh.

Another excellent strategy is to invite your reader to leave a comment. Comments are picked up by search engines as new content. The only problem with allowing comments it the potential from comment spam.
