Each business can benefit from starting a blog if their customers are interested in the content. So, the first thing you need to consider is ‘What would my customers want to know about my business?’. For example, if you are a landscaping company your customers might want to know about what in season or even to see some your work.
Secondly, you need to promote your blog – you can write a blog and no one will visit it if your site unless you promote it. So, you need to 1) use free internet promotional techniques e.g. facebook, linkedIn, twitter and 2) put a link to either facebook, your blog, or twitter on you adverts and at the end of press releases.
Thirdly, you need to allocate time to 1) writing the blog, 2) creative time – to come up with the ideas for the blog, 3) editing the blog and 4) posting and promoting the blog.
Ultimately, if you meet the first criterion – i.e. Will my customers be interested in what I have to say or what I do – you should start a blog.
