If you contact the webmaster of a site as an Internet marketing specialist or other SEO professional they will think you’re getting paid for doing so, which encourages them to ask you for money.
Beware of forming a bad relationship with the webmaster because it can reflect on the way they’ll view your company. But if you form a good relationship they can be your best friend as they can secure links for you in the future.
It’s best to get an e-mail address for your client’s domain with your name. Another option is to use their brand name with a free e-mail account like yahoo.
These e-mail addresses will help you form a good image with official sites like .edu and .gov.
You can also contact webmasters as a fan of the brand. E-mail them stating that you like their website but that they forgot to mention your favorite brand. Hopefully they’ll take you seriously and add it onto their list.
