Difference between SEO and Pay-Per-Click methods

[genilia]

Pay per click is an advertising model used on search engines, advertising networks, and content websites/blogs, where advertisers only pay when a user actually clicks on an ad to visit the advertiser's website. Advertisers bid on keywords they predict their target market will use as search terms when they are looking for a product or service. When a user types a keyword query matching the advertiser's keyword list, or views a page with relevant content, the advertiser's ad may be shown. These ads are called a "Sponsored link" or "sponsored ads" and appear next to or above the "natural" or organic results on search engine results pages, or anywhere a webmaster/blogger chooses on a content page.

The first being 'PPC' and the second being 'SEO'. As these are both acronyms they can be fairly impenetrable to the layman.Both of these options have strengths and weaknesses. While PPC has a more immediate effect, it is limited to the amount of money you put into it; whereas SEO has the potential to generate massive amounts of self-perpetuated traffic for a short amount of money with a little bit of luck.
