Compare SEO vs Other forms of marketing

Google Adwords (Paid per Click) (Sponsored Links)	Cost Effective Marketing You are no longer paying each time someone visits your website. At $4.00 per click, paying per click gets VERY expensive VERYquickly. On average, SEO for Natural Ranking is about 10-30% of the cost compared to Paid Per Click Schemes. (not to mention better results)
	Better for customers who are still researching Natural Ranking is better for customers who are still researching and comparing products and services. Your website is generally in the same position the majority of the time; whereas with PPC, your position shifts randomly. 60% of internet users recall the search term they used to find your website in the first place, and may use this search term up to 5 times before bookmarking or remembering your website.
	Better overall credibility and branding "36% of search engine users believe that the companies whose websites are returned at the top of the search results are the top brands in their field" (Ibid, 2006)
	Multiple search engines The frustrating part about PPC is that it only works for a particular search engine. To get a similar result in Yahoo, Google and MSN, you'd have to enter 3 separate PPC campaigns, whereas SEO typically works on most search engines.
	Remove Click Fraud Click Fraud is a big problem. It is estimated that 10-30% of your traffic from PPC campaigns may come from your competitors. In some cases, competitors can sabotage your PPC campaign by employing software programs or low wage staff to click on your PPC links (Adwords). Although preventative measures have been taken by Search Engines to reduce the effect of Click Fraud, it is still far from faultless. Currently, there is a large class act law suit against Google for Click Fraud. With SEO, you're not charged each time someone clicks on the link.
Business Directories, both online or paper versions.	Traffic Volume Put simply, Google has the potential to drive more visitors to your website than any other form of marketing. Paper based marketing doesn't offer "click here to visit the website call-to-action", and other online directories just don't have the traffic volume.
Banner Advertising or Content Based Advertising	Targetted Traffic Performance There is no other medium that is going to drive targetted visitors to your website than a search engine results page (SERP). We're talking about someone who has searched for a specific product or service and has found your website.
