Doug Karr has helped me come up with a great explanation of keywords and compending.  A fantastic way to explain Compendium Blogware, what we do,and how we can help you win search engine optimization. Keyword focus isn't simply driven by content itself, it's also driven by a number of other factors including URL construction, backlinks, titles, keyword density on related pages, positioning of the html in the page, and even formatting of the text itself.  Our compended blogs concentrate keyword densities of like terms (your keywords and synonymous terms) and organize the posts on the compended page for maximum search engine attention.

If you begin to focus specific keywords in your posts, you WILL see some lift in those results; however, without the optimization that is provided by a compended blog, you may find it difficult to place in those top 4 search results depending upon how competitive the keyword is.  This is what's so great about blogging in general - you can really attain a lot of search engine traffic - even on keywords you've not optimized for.  However, when you do optimize, you'll definitely garner more attention.  As well, you'll gain traffic and attention on peripheral search phrases that are relevant to your business.

75% of corporate blogs fail - usually because of the lack of relevant traffic (or little traffic altogether) that their blog attains.  That said, don't hesitate to utilize that strategy if you have additional keywords that you wish to attain.  When you really want to hit the homerun and 'own' the keyword or phrase, nothing will work better than a compended blog, though.
