Pay-Per-Click (PPC) and search engine marketing allows you at the auction principle for you relevant keywords and keyword combinations, searching for the user in the search engines such as Google, to offer. You pay for this type of advertising only when a user actually clicks on your ad.
Payper click advertising offers, depending on the desired keywords enormous, short-term customer potential. Unlike the classic search engine optimization, which requires a longer start-up period, you will be forwarded to the PPC marketing quasi from the first hour of website users. Their number is only limited by your advertising budget.
However, it is also always linked with this form of advertising to the PPC auction. You pay nothing on Google Adwords, comes just as fast and not a single user more. A sustainability, as it offers the professional search engine optimization does not exist in SEM marketing.
The price is to be paid per click is determined firstly by the prevailing competition (how many competitors also offer on selected keywords you) and secondly by the quality of the built-up of you advertising campaign.
