Do webmasters usually receive commission for sales that come in off the internet? Let's say a company has salespeople that receive a commission of the sales they bring in. On the website the e-mail orders are equally divided between all the sales people. Each of the sales people are receiving a percentage of the sales from the website also, although the webmaster that created the site, did SEO work to get it to rank well, etc. does not receive any commission.
Is this standard practice or do webmasters typically receive a portion of the commission or some other incentives off performance of a website?
