I was considering constructing my own blog, and it got me thinking . . . How do blog search engines, like Technorati, tell the difference between blogs and conventional Web sites? What makes a blog a blog?
Yes, Every blogging platform have unique structure. If you take blogspot.com they have a unique character like the same other blogging platform has its unique character to identify them. Every blog has a common features Like this search engine will follow certain rules to find a blog
Its simple.. Structure ofcourse. Wordpress and blogspot the 2 most commonly used platforms have unique structures..
I have got the doubt many times too. Its really confusing. I sometimes thought that the blog search engines will add each blog platform every time they find a new one on the web. But this is not correct too. But they have a manual pinging option. That pinging code should help you a lot to find out how it will and how it wants to format the posts in a blog.
I think you should ping once you update your blog with new Posts. Don't Ping too much otherwise you will get banned for Spamming. I ping my Blog once in a day and it works fine with me.
