When it comes to generate a high Return on Investment (ROI) there is no better system of marketing than SEO.
ROI from professionally organised search engine campaign with top natural ranking in Google can give you up to 50 times your investment. For example, for each £500 you spend on professional quality SEO, you can generate a return of up to £25,000.
Organic SEO results have a much better conversion rate than a similar Pay per Click (ppc) campaign.
Web users trust more in Google results generated from natural keywords rather than ad-words results where companies pay for the rights to be shown for certain keywords.
