In my short time blogging on Blogger, I have run into an interesting issue that seems very common. It seems by default, that Blogger blogs will allow archive pages and in some cases even post labels or categories to be indexed by search engines.This is not what you want, as most search engines frown on duplicate content, and this will fill the search results for your site with many useless pages for potential visitors.
One of the most important aspects of your blog is "how" it appears in search results across the major search engines such as Google, Yahoo, and Bing. If your archive and label pages are being indexed, it could potentially hurt your rankings, or worse, rank those archive or label pages higher then the actual article. The good news is we can take a few simple steps to remedy this issue.
