Is it unusual for a SEO/SEM firm to NOT disclose to their clients what their process for SEO/SEM is? Isn’t it the client’s right to know exactly what is being done on their behalf??
I certainly advocate education between SEO and client, but I do know of many SEO operators that prefer not to reveal their process. By the same token, some clients will be very interested in learning what is being done to their site, while others will have no interest at all.
I particularly hate it when SEO/SEM operators claim that what they are doing is “proprietry” or “secret” – really there is no secret sauce for SEO – just acquired knowledge, experience, trial and error!
