The most important thing to remember is that SEO and PPC are complementary strategies. There is no conflict between using the two techniques, and both will be more successful if used together as opposed to using just one or the other in isolation. The most obvious difference is the price tag that comes with these two techniques. You are paying for the clicks that PPC sends your way, whereas the clicks from SEO are free. Getting to the top of the SEO tree for your most lucrative search terms requires hard work. Getting to the top of the PPC tree for the same search terms requires money (just how much is dependent on the competition for that particular search term) and work. Both PPC and SEO require hard work researching keywords so that you know which search terms to buy (for PPC) and which terms to optimise for (SEO). Different creatives per search term or group (PPC) and different HTML coding for each page of your site (SEO) both need to be written to entice customers. SEO has the added complication that the title tags need to be written with the search engines in mind as well. PPC can be characterised as a quick boost of traffic to a particular site. If you’re willing to pay the price of the clicks, then you can buy a top position for your chosen search terms in the major Pay per Click engines. Providing your search term has enough traffic, and your creative is tight and enticing, you should notice a bump in traffic. SEO is a slower process. You are unlikely to see major changes to your traffic in the early stages, as so much of SEO is to do with the structure and environment of your site. However, the effects of SEO are both longer lasting and cheaper than PPC. With PPC, the moment you stop your campaign the traffic dries up entirely. SEO on the other hand will continue to bring in traffic even if you stop SEO work on the site, although you will need to ensure that your SEO campaign keeps abreast of changes in the search engine algorithms.
