Issues with Google-Bot crawl vs. Roger-Bot

[IOSC]

Greetings from a first time poster and SEO noob...

I hope that this question makes sense...

I have a small e-commerce site,  I have had Roger-bot crawl the site and I have fixed all errors and warnings that Volusion will allow me to fix.

Then I checked Webmaster Tools, HTML improvements section and the Google-bot sees different dupe. title tag issues that Roger-bot did not.  so

A few weeks back I changed the title tag for a  product, and GWT says that I have duplicate title tags  but there is only one live page for the product.  GWT lists the dupe. title tags, but when I click on each  they all lead to the same live page.  I'm confused, what pages are these other title tags referring to?  Does Google have more than one page for that product indexed due to me changing the title tag when the page had a different URL?

1. Does this question make sense? 2) Is this issue a problem? 3) What can I do to fix it?

Any help would be greatly appreciated

Hi Jeff

1. Yes it makes sense

2. It could be, it could affect your SEO rankings if Google catches it as duplicate ontent.

3. This is how you can fix it... create a new site map (personally I like vigos sitemap generator), and submit it to Google Webmaster Central. This will tell Google exactly how many pages you have, which ones should be indexed, etc. If you already submitted the sitemap manually try re-doing it.

I hope that helps
