How is my 301 redirected site stealing rankings from the main site?

[DA2013]

Hello,

I have a site, drhobelt.com, that 301 redirects to the main site, drhonow.com.

Not only is drhobelt.com still indexed, but it recently stole rankings from drhonow.com for "decompression belt" related terms.

What could be causing this? How do I reclaim the rankings for drhonow.com?

Thanks for reading!!

When did you implement the 301 redirect? It can take a while for Google to catch on to the redirects, especially if you have a large site.

If you want to see the transition sooner, use the Change of Address tool in Google Webmaster Tools:

Thanks Takeshi!

I'll have to find out for certain when the 301 was implemented, but we believe it was a long time ago -- over a year.

One more item: This business occassionally runs tv and radio ads sending traffic to drhobelt.com, leading me to suspect this might be the reason drhobelt.com is still indexed and is even taking rankings away from drhonow.com. Does that make sense?

Thanks again Takeshi, I love reading your responses whenever I see you on Moz!

Hey Daniel,

I doubt that sending radio traffic to the old URL would have any impact on which page is ranking in Google.

Another thing you should do is add canonical tags to all of your pages. That will also help Google tell which version of the page is the correct version to show, and also helps prevent a lot of common duplicate content issues.
