The Daily Rundown (link removed as the site is no longer there)has this interesting piece of analysis about what people are searching for on Google.
‘ 28% of Google searches are for a “product name”, 9% are for a “brand name” and 5% are searches for a “company name”. “Brand” keywords also have a 8x higher ROI than generic keywords. Not sure if that is for all searches or just consumer-product related searches, but either way it demonstrates the importance of making sure your site shows up on the SERPs for your brand.’
Now that is some useful information that fits pretty well with the anecdotal evidence that I’ve seen over the past year. So if you’re reviewing, previewing or just talking about a product you should be as specific as possible with your keywords – put them in your title, in your image tags, and make sure they’re included numerous times in the body of your post.
