A few years ago that might have been a rude-sounding question, but now many people are on-line sharing their views on all sorts of topics. Yesterday someone contacted me for homeopathic advice who had found me on the internet and who said 'and you blog' as a reason why he contacted me.
Blogging is a way of spreading your on-line presence into subjects that people are interested in, it's a way of showing where your expertise lies and it shows that you are still active in your field. No-one wants to waste time looking at a website only to find out that it is out of date, or worse, that the business doesn't exist any more. It encourages potential clients to value your offering and get in touch.
Also, you will notice that I have linked to my homeopathic website and homeopathic blog in this blog and will therefore improve my search position as a result.
Create.net run a free and simple blog facility as part of all their website packages and I also recommend wordpress. If you want to find out if a blog would help you market your business and need help setting one up or writing copy for your articles, contact me.
