There are a lot many reasons why blogs can be useful to your SEO efforts. Blogs and blogging have become hugely popular in recent times. With free blogging by Wordpress, Blogger and other free open-source blogging applications, anyone who has little or no knowledge of coding can start a blog of his own.

Blogs give fresh content – Search engines look for blogs and forums generally for any topic of discussion. This is because search engines view blogs as a medium where fresh content can be obtained.

Easy Maintenance – Blogs are easily maintainable. They require few or no maintenance. Most blogging applications are search engine friendly. You would not have to end up spending huge time and resource in optimizing the website. You start to add content once you install the blog and choose your template. Installation would take few minutes.

Blog Growth – Blogs grow faster than any online medium. Blogs expand and interlink internally providing an excellent place for search engines to gather food.

Syndication – Blogs help syndicate your content to another website. This helps trade content which also helps external linking.

Social Media Bookmarking – Social Media websites provide huge scope for external linking. Getting your posts onto few social media websites can provide modest traffic back to your blog.

Internet has been spammed in all possible ways from e-mail boxes to blogs. It looks inevitable to avoid spam. There just seems to be a possibility to reduce spamming.

Matt Cutts, Google Engineer and Head of Web Spam Team has been fighting spam for the last eight years. Speaking to web enthusiasts in the recent Web 2.0 Expo 2008 in San Francisco, he provided ample tips on fighting spam on websites.

He also mentioned that Captcha systems are not secure and that spammers can bypass CAPTCHA systems easier. Matt Cutts also stated how bots are signing up on Blogger accounts and use accounts to advertise their products and services.

Matt Cutts made it clear that search engine optimization is not spam and that Google by no means hates Search Engine Optimization. Cutts also requested web masters to inform Google Webmaster Central sites that use black hat techniques like white texts on white background to bring up search results.

Looks like Google has been ignoring Blogger security issues lately.  Bots are bypassing the human verification step and creating spam blogs automatically. This would be a serious threat to Googles security and Blogger reliability.

CAPTCHA a type of challenge-response test is a verification process where the subscriber has to type the numbers/text that are displayed on an image. This helps find out if the blog has been created by a human being or created automatically by a bot program. CAPTCHA has been used by almost all online registration steps after it was coined in 2000 by Luis von Ahn, Manuel Blum and Nicholas J. Hopper of Carnegie Mellon University  and John Langford from IBM.

It is reported that Google has not yet allocated resources to work on Blogger. The Blogger team is still fixing bugs and gets away with work. This has lead to users opting for Wordpress and other free blogging services present online.

This result in security ignorance could be due to Google having other top priorities which could yield more income to the company.
