Blog Quality Guidelines

Technorati's goal is to collect interesting original content from across the English-language blogosphere.  A precise definition of what is or is not a blog or news site is difficult, but here is an explanation of many of the things we look for (or don't look for) in a site.

To be included in Technorati's index, a site should have:

• Original content. Excerpts from others used for commentary & discussion are, of course, perfectly acceptable.
• A public Atom or RSS feed (otherwise we cannot access the content)
• New articles posted at least monthly. We only index 30 days' content, so anything older than that will not appear on Technorati.
  

• Intensive use of others content. Attribution is not sufficient -- if your site primarily reproduces content written by others, even with permission, we will not include it, as we do not want duplicate content.
  If plagiarism is verified it will result in removal of the offending blog from Technorati.com
• Excessive reposting of the same content to multiple sites. Again, we do not want to index duplicate content.
• Auto-generated text in place of original writing
  
• Excessive linking, especially to a single site
• Excessive tagging, especially when irrelevant
• Excessive commercial intent: if the sole purpose of the blog is to sell a single product or program or direct readers to a specific site, it's not acceptable. (Most corporate & small business blogs do NOT fall into this category)
• Excessive pay-per-post, especially if not disclosed
• Overly repetitive content, where new posts are mostly simply restatements of old posts
  

• Store catalog listings
• Video, music, torrent, etc. download listings
  
• Auto-generated content, pulling in data from Google, Wikipedia, Amazon, consumer review sites, and/or other blogs and sites.
• Free posting / article publishing sites, where anyone can sign up and add posts or articles
• Blog planets & aggregation sites
