Here's the question:
"Multiple divisions of our company want to rank for the same keywords. Are there any tips for how to approach this type of situation? It seems like our company will be competing against itself in SERPs for page 1 rankings."
The author here says that people are far too worried about keyword cannibalization these days. The reality is that if you are working within a company where it makes sense for several products to rank for the same keyword, you very may well run into a situation where one of your sites will rank above the other. However, in most cases, this just isn't the big deal that Bill over in "blue widgets" wants to make it.
Just because more than one product is ranking for "blue widgets" doesn't mean that getting the sale or lead is a zero-sum game. In fact, by having a multi-divisional corporation rank for many keywords around the same topic, you have a much better chance of creating a branded preference for your goods and services. You also have a better chance of being the site where the sale takes place.
Divisions Should Share Data
It's best to share data with your divisional counterparts. When you keep things from each other, you can easily make a hostile work environment. Heads of divisions need to communicate with each other on how they are going to work together, rather than how they plan to beat the competition in their own company.
Why make SEO complicated?
In reality, te author says their experience has shown them that ranking above a competitor by a couple of spots doesn't always translate to an excess of sales. If your company has multiple divisions ranking for specific keywords around a topic, you should be able to track exactly how much traffic and how many sales those queries are driving. You need to communicate these figures to your higher-ups. By working to increase the overall pie rather than just what is collected by each division will make the entire corporation stronger.
Compete - But Help One Another
You want to outrank your divisional competitor, but if you don't (and they outrank you) it's still good for the overall organization. You should be providing help to your divisional counterparts when they aren't ranking well. Give each other tips and tricks on how to rank higher in SERPs. If you and your divisional counterparts hold the number 1 and number 2 spots of the SERP, you are more likely to get the sale - or at least create a brand preference.
