Let's say you have a website that sells widgets and we sell widgets and have a blog with great articles about widgets, etc. BUT we want to build back links and are having a hard time getting people to link our widget site because for whatever reason they hate the idea of widgets.
So instead, let's say I write this nice professionally written article about duck tape and submit it to a respectable web directory with great domain authority who agrees to list it in hardware link section. The article simply talks about 100 great things you can do with duck tape and 99.9% of the 500 character article has nothing to do with widgets but maybe for good measure I'll make a simple comment like, "hanging widgets is fun with duck tape" just to get that widget keyword in there. :)
Now, I know sites like CNN have multiple categories and their subject matter is all of the place. They can talk about everything from sports to fashion. BUT if you operate a site that we'll call superwidgetshop.tld and you try to keep the subject matter on anything widgets, does this new duck tape article hurt me by getting off the subject or does the fact that I'm landing a good backlink from a great source that goes to my domain, in the end, help more?
I see competitors of mine do this because like me, they can't land back-links for widgets. :) So instead they find ways around this by creating non-widget content on their blog that directories or other resources are more likely to link to. According to reports that I've run, those links are very powerful for them and help build their strength. I want to do the same but at the same time I've taken a lot of time and energy in keeping the content of my site relate to widgets.
What are your thoughts? I always thought sites were judged as a whole and not by single pages? Am I wrong? Meaning if a site has lots of good resources that relate to a particular keyword, isn't that important and that being the case, isn't it more important that the overall conversation of the entire site stay on topic if you hope that dominate a particular keyword or related series of keyword terms like widgets, buy widgets, online widgets, best widgets, free widgets, download widgets, etc. Let's just assume what you've been trying hard to stay on topic, but now you totally mix things up and now come an article about, hmmm, duck tape? lol
