What's your favorite method of getting SEO clients?

[abhayhendre]

I've been using cold emailing since last few months to try to get some SEO clients, but I'm not having any success.

I'm personalizing my email for each prospect (by adding their name, business name, industry, website url etc). I'm getting around 35-40% open-rate for my emails.

I'm targeting laser eye surgeons from different locations. While choosing a prospect, I check if they have low traffic, less backlinks, bad/average quality website design and things like that.

What am I not doing right?

Do you guys have any suggestions? How do you get your clients?
