I'm curious as to what things you take into consideration when saying a price to a client for SEO. How do you manage to explain him that there is no guarantee ? Also how much do you charge for page2/page1 ? You have a different price for rankings ? I'm curious about all those facts, as I probably will try some offline SEO, and I want to know how others are making their prices based on competition and so on, so some examples would be more than welcomed. Thanks guys.
