How much blog spam is produced in 5 minutes in a quiet Sunday evening? What is the ratio of spam blogs in the most popular blog services? To answer this question I present you the results of an experiment analyzing ping data and manually reviewing blogs.

The relative ease of creating and maintaining blogs makes them ideal tools for spamming search engines. Spam blogs or splogs serve two basic purposes: making money from advertising and affiliate programs, and participating in link farms. But making money from AdSense and providing nepotistic links are not what it takes to call a blog splog. Otherwise we would have to classify all blogs showing ads or promoting a business as spam; and there are thousands popular, quality blogs that would fall into this category. The distinctive feature of a splog, however, is that it has no use for its visitors. Should Google ban a splog from AdSense and prevent its links from passing on authority – such a splog would have no more value or purpose of existence. So my definition of a splog would be “a blog with the only purpose of showing contextual or affiliate ads, or boosting link popularity of certain target sites”.

1. Without sitemaps, a search engine visits your site’s pages through links on and off the site, indexing and ranking those pages it deems worthy of being indexed and ranked.
2. When a search engine crawls your site and fails to index particluar pages, you have a signal from the engines that those pages lack the necessary components for inclusion, be they architectural, link strength, content-related, etc.
