This seems to be the age old question from a lot of business owners, service companies, attorney's and any member of the public that has a website. The short answer is yes! Blogging about topics related to your field or service is a good signal to the search engines like Google, Bing and Yahoo. You don't have to post all the time and be a journalist, but a blog posted once or twice per month will go a long way over time. Think about twelve months from now, do you think having twenty plus blog posts and articles about your specific service would help your website outshine the competitors? You guessed it, and astounding Yep.
Google looks for relevant content being added to your website when they crawl the web every couple of days. The fact that they do that, is part of the overall SEO process and a reason that we exploit it. Once they pick up on the new content that you have added to your site, it helps give you a push to nudge ahead of the next in line website that has been left stranded for the last 2 years. Probably 90% of websites out there in your industry that you are competing with locally haven't updated their website in two plus years. Heck, five or ten years is not uncommon. So, it isn't that difficult to see that posting regular content on your site will give you that competitive advantage in your local online space. Regularly posting articles about your experiences in the field, helpful topics, and how to articles will go a long way in making your website stand out among the sea of outdated ones.
