Hi!
I am new here and i found this PPC category; i don't understand what is it about and how this can optimize a website.

Many search engines introduced the pay per click (PPC) action; it is very important as seo, but PPC is the favorite of advertisers because usually they can see results immediately. This method brings traffic to your website; it is very simple to implement ppc on a site. You have to place and ad on your page with links to other websites given by the search engine; the links are results pages for a keyword related usually to the site's theme. You can start a PPC Campaign by registering to a Search Engine and install the code you receive on your website. You can ask for a search engine to give one of its programs and this should include all elements of pay per click strategy.

Pay per click is an advertising model used on search engines, advertising networks, and content websites or blogs. Advertisers believe that their target market would type in the search bar when they are looking for a product and a service.
Pay per click ads can show on content network websites. If so, ad networks like Google and Yahoo attempt to provide ads that are relevant to the content of the page where they appear.
Very popular search terms can cost much more on popular engines.

good.

Thank you,
