Search engine optimisation & Pay Per click

 
 
SEO & PPC

The main difference between Search Engine Optimization (SEO) and Pay Per Click (PPC) is that traffic coming from SEO (organic) is free while traffic generated from PPC is not free (as the name implies you have to pay a cost per click).

This is also the reason why you may sometimes see the terms organic search engine listings and paid search engine listings (or Paid Search Advertising – PSA).

Both SEO and PPC are part of Search Engine Marketing (SEM) which is one of the tools you can use as part of your overall Internet Marketing campaign.
