Keyword Self-Cannibalization Concern

[JerDoggMckoy]

Right now I have an E-Commerce website that has layered menu properties. I have one page trying to rank for "NextGen Digital Ballast" that is the main category page. However, on that category page I link out to three product pages which would be "NextGen 400W Digital Ballast", "NextGen 600W Digital Ballast" and "NextGen 1000W Digital Ballast". The on page ranking factors tools is saying I may need to consider making adjustments because of the potential self-cannibalization, but I wanted to get some feedback to see what others thought about that. Thanks.

It depends upon how many very similar pages you are going to have.  If you have dozens or more then a cannibalization potential is very real.  However, if you only have two, three, four then that gives you the potential to have multiple pages in the SERPs.  Nothing like having #1, #2, #3 and #4 for a query.

For small numbers it is more of an opportunity than a problem.

Thanks for the response EGOL. Right now we have 3 different brands of digital ballasts. We have our main digital ballasts category, then we have NextGen, Phantom & Lumatek digital ballasts, and each of those all have the NextGen 400w digital ballast, the Phantom 400W digital ballast, the Lumatek 400w digital ballast, also for 600w and 1000w.

Where I get confused, the example of the on page optimization states that if you are trying to rank for elephants, then you can use "baby elephants" as a different page. Isn't this what I'm essentially doing then? I have digital ballasts, but then they are also broken down into 400w digital ballasts, 600w digital ballasts, NexttGen 400w digital ballasts, Lumatek 1000w digital ballasts, etc.

The idea here is conception. Google will conceptually see the difference between an elephant and a baby elephant as being two different items.

Although it should see your products as different, the warning comes from page apparently being the same- no distinction.

If you find you are not ranking well, or more so, someone slipping inside your ranking, try 400W NextGen Digital Ballast and 600W NextGen Digital Ballast

I do agree with EGOL that for a few pages this should not be that big of a deal, but changing the order of keywords here should not be either.

I hope that helps

Great discussion and suggestions here already, but I wanted to add this post in case you haven't seen it: http://www.seomoz.org/blog/tactical-seo-how-many-termsphrases-should-i-target-on-a-single-page

There's lots of good stuff in the comments there, too.

Thank you everyone for the help. I feel confident that we can just continue on like we are, and if I notice any issues, then I can try your suggestions of the keyword order and also following the examples of that blog post. Thanks again!
