Pay per rank
Personally I do not like this model and will never sell based on their ranking. First of all because there is no sure way to an objective set of meassure and also because I do not know the list is in itself sufficient to prove the value. The value is not listed but visitors and conversions that could lead.
Price on performance
It sounds simple you get the customer on the first page and they pay you. This method is problematic especially with the introduction of personal research. You may find you educate your customers on search engines so they can validate the data you send your monthly report. I spoke with business owners who have used this type of service and it seems to turn into paying us if you want the relationship. The customer pays only when they think that the SEO company has done enough. This might seem the fairest but the frequency of referencing the firm is left out of pocket.
Pay Per Action
This is actually marketing only afilliate at its best. We provide transportation which pays us its value. This model has proven to be one of the best for us to get more customers the freedom to do what we know is right to do and care less about information as long as we are producing a good steady income. And if not you do not pay. This works Even in my experience customers do not almost never revoked the offer why should they As long as it works they make their money, and if does not work do not pay anything.
Pay per click
Long before the PPC engines came around we where charging systems SEO work on external domains on a CPC. It works a lot especially working for major media agencies as it is very familiar and easy to budget. In recent years some companies have also moved into a model pay per click site optimization based on the increasing number of visitors to the site organic customers.
