Great post by Napsterization on comparing the URL incoming link search amongst the various RSS/Blog engines.
Check out the comparison chart…great to see the differing indexing methods and the type of data that is indexed, and much more…
Duration of link counts
- Bloglines - forever (shows history of every incoming link)
- Technorati - only if still on the front (home) page
(only counts incoming links from the blogs front page)
(although it still matches keyword searches with posts that have fallen off the front page)
Alert/Watch list for incoming links
- Bloglines - No (the only one that doesn’t provide an RSS feed)
Duplication of posts
- Same posts may be indexed from multiple RSS feeds, ie. you may have 2 or more types of RSS feeds, or someone else may be re-syndicating your content
…also Bloglines includes links to own blog
So Technorati can be used to view current activity (if links counts have fallen off the from page, it is considered not current), whilst Bloglines is consulted as a historical link count.
Bloglines only shows results from a blog if it being subscribed to by someone using the Bloglines RSS Reader
Blogpulse - enter the “http://” part in a URL search to get proper results
Bloglines and Technorati both index blogroll links
…keep tuned for more of this 6 part series.
see my post on RSS engine indexing
…if the blogs RSS is not full-text then not all the possible incoming links will be found….and even though some engines like Technorati crawl HTML, it still may not help as the front page may only have an excerpt of the post.
