A made a 12 month proposal for a SEO services for a website that streams music. It currently has around 5k artists and 50k tracks that need to be optimized. The client told me that they want to sign up a shorter contract and if they see results, we will continue working together. How to explain to them that SEO takes time and I need 1 year to execute the strategy properly?
Google says you need "4-12 months" here (video @ 1:27)...
Double your price, and offer a 50% discount + a commission structure (paid regularly, NOT at the "end of a project")... if they sign a 12 month contract so you can do your job properly & according to Google's recommendation.
