There are a few ways to boost your Internet presence without paying for advertising.
A short video on YouTube with the correct 'meta-tags' will offer an immediate - if short-term mention for your company in the search results. This is one reason why we offer a free video service.
You can also take video on your phone and send it to usfor uploading. It doesn't have to be a 'Hollywood Production' to get noticed!
