With the recent news that Google has overtaken ITV1's advertising revenue in the third quarter of 2007, it seems Digital marketing has finally come of age in the 21st Century, according to a PR Web release.

An analysis for The Times over a 3 month period in 2007 saw Google exceeding ITV1 by £10m in advertising revenue, representing a UK annual growth for Google of approximately 43.5%, the report added.

Refreshed Media, an online marketing firm, warn that without expert advice and guidance, businesses could lose thousands in their efforts to utilize this medium.

Sarah Baker, Sales and Marketing Director of Refreshed Media, has this to say: "As a digital marketing agency we are delighted the web is coming into its own and being used as the effective marketing tool it is. However, as a specialist agency we would urge people to seek advice before parting with their cash. We are passionate about online marketing, and as a full service agency, we can help any business make the most of this powerful tool. If you don't know your SEO from your PPC, then talk to someone who speaks your language and that of the digital world to get the best from your marketing budget."

There you have it, if you have no idea how to do it, consult the experts.
