Could Having Blog Posts as Home Page Cause Keyword Dilution?

[WilliamBay]

Something I've never been a fan of is having a blog as the home page of a site. I've always thought that it's a bit like walking into someone's house through the kitchen out back.
If it's a vistors first time, it can be a little disconcerting or ackward even if they are not familiar with the writers style.

But something just dawned on me, and I'd love a second opinion on this.

For websites that focus on multiple keywords (in my most of my client's case it's usually a mix of Wedding Photography, Engagement Photography, Portrait Photography, Family Photography, etc).

A lot of these clients will include the photos in a blog post along with a snippet of text that may talk about the people they're photographing and maybe a bit about where they photographed. But they're usually optimizing for the overarching keyword (Wedding... Portrait..., etc as per above).

Now I'm wondering if having three or 5 posts on the home page, where most of them are focusing on a specific keyword like New York Wedding Photographer, is actually diluting the keyword they are trying to rank for.

My theory is that if I have them move their blog to a domain.com/blog, and solely focus on the desired keyword on the home page, that they would do substantially better in the SERPs.

Can anyone subtantiate this?

Thanks!

Thanks for that EGOL. That does make sense.

There are two parts of this....

Offpage... all of your links will remain the same no matter what content you display.  So if your anchor text is optimized there that should support stable rankings

Onpage... if you keep your title tag, H1 and some other onpage mark-up in place then different topics rotating through the blog should not be a huge factor.

I believe that the factors above are more powerful than the loss that you might suffer through keyword dilution.  And ,  if you want your site to be like this just earn a few more links to support your current rankings.  Isn't that what the blog is supposed to do?
