If you are running the SEM for a small business, you probably have the staff on a weekly or monthly blogging schedule, depending on the size of your staff and the frequency of your updates. An age-old problem is, however, blogging yourself out.
That happens here, at SourceTOAD, to be sure. Once in a while, I find myself beating my head against the wall, trying to make a great blogging idea splat itself against the brick of our office partitions. This isn't really effective, however, at much more than creating a really neat blood-spatter design above my desk.
What I should do, instead of resorting to self-mutilation, is pull out my old keyphrase list that was put together before we started our whole SEM campaign. From there, I can take a bunch of related and applicable keywords and phrases and write my blog around them.
Now, that's not to say that it should be a list of keyphrases with 'and' and 'also' sprinkled in. You should still focus on keeping it interesting and informative to your reader. Blogging for your business is about more than search engine ranking; you may also gain clients based on your insight, knowledge, and understanding of your chosen profession.
