Blog started out as a sort of personal diary on the Internet. It is convenient to blog on the Internet due to the easy availability of free software. However, commercial companies soon realized the advantages of Blogs in reaching out to their customers and hence Blogs become commercialized.

This is really not too bad as we can know the newest information of the shops or stalls that we like. However given the fact that blogs are “live” content, search engines begin to place a higher priority in indexing the blogs as fast as they can. This caused the issues of spammers making use of blogs not as a diary or as a tool for business but propagating blogs with useless content so as to draw the search engines to it and index it. This is some sort of blackhat SEO. Nowadays it is tough to find a good blog, rather most blogs are just created automatically by blackhat SEO companies to push their sites up the search engine rankings. It is extremely sad to see such a useful tool being used and abused by such black hat spammers.
