Avoiding Duplicate Titles

Most wordpress sites are now being penalized by Google because of the “Duplicate Title Tags” problem.  WordPress blogs will have the multiple links pointing to the same title tag in two locations a sample will look as follows:

/business-process/transcript-twisorg-dec-25-2007/‎
To Google, this fact alone makes your site look spammy and it will delist the page and result in your site not being found in search engine results. So obviously, you need to correct this. An easy solution to avoid this duplicate title tag would be to use robots.txt file containing the following entries:
User-agent: Googlebot
Disallow: /*/trackback
Disallow: /*/feed
Disallow: /*/comments
Disallow: /*?*
Disallow: /*?
Disallow: /*page/*
User-agent: *
Disallow: /cgi-bin/
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-contents/plugins/
Disallow: /wp-contents/themes/
Disallow: /trackback
Disallow: /comments
Disallow: /feed
