Hey Guys,
I understand where you're coming from in terms of competitive analysis and figuring out whether you'd be hard-pressed to have multiple pages ranking for more competitive terms. I also understand that there are certain aspects of a topic that may justify different pages (for example, water filters, home water filters and under sink filters may require different page urls while water filters vs. water filtration may not) but I'm more referring to the algorithmic aspect of this.
In general, does Google LIKE to see that you're creating multiple pieces of content on a topic to deem you an "expert", or is there no benefit to doing so from that standpoint? I've seen similar terms that I believe require different pages/urls competing against each other and hurting the top ranking page in the SERPS.
For example, I had a client who had sold CAD software. Their home page was optimized around that term and ranking middle of page one. They had ANOTHER page that was for a free CAD software (stripped down version) that initially didn't rank for the "CAD software" term. At some point, this free CAD page starting creeping up into the top 25 on Google, and as it did we saw a direct correlation with a drop off for our home page. Instead of having one page ranking at #4, we now had TWO pages ranking #10 and #11.
Make sense?
