Why have a blog created in wordpress, blogger, tumlr vs just adding a new button to your existing website page? Existing web page has keywords, titles, mega tags...
My answer is that possibly some people choose a blog when they don't have a website or a need for a website.
The reason I'm asking is that I updated my blog this weekend and created one for my husband's business, but now am questioning why when we both have websites.
I love this 'banging the head on a brick wall...! I seem to be at that point so often these past two weeks.
