generate lead

Hi friends i would like to know that how can i generate b2b leads from blogs to main website to attract more visitors :)

Hello guys, I m doing seo for companies, one of them contacted me and proposed me to generate leads for them ( on a specific market) by building a website , rank it and send them the leads or any other way, they don t want seo on their website, they want a third party to generate leads for them...
