My Friend Barbara Rozgonyi at Wired PR Works has some interesting advice, advice I am often heard relaying to clients since launching my own blog in October 2006….
Excerpt from post – Stats Weigh In
Hmmmm . . . in my case I’ll pick the blog. I’m thinking of moving my company site onto a blog platform to save:
– time – it’s so much easier to write a blog post that it is to write site copy and then format it, upload it, check it and wait weeks for search engines to add the page to their index
– money – self-hosting a blog costs less than the $19.95 web hosting fee and blog design is mostly do-it-yourself, even the best blog designer charge a much more reasonable fee than graphic designers
Disclaimer: A well-performing web site cannot be replaced by a brand-new blog. If you have a high Google page rank, then you may be better off keeping your site. Be sure to add in an online newsroom or other component that updates your content frequently.
Best of both worlds: add a blog to your site
