When it comes to ranking your website, you need a solid strategy, velocity, and to get links from friendly neighborhoods, etc. I wanted no risk on my website. So here's how I used a Pinterest board to rank.
1. I created a board with the main keyword.
|New York Plumbing|
|New York Plumbing is a very Lucrative Business. Every Kid in New york aspires to be a new york plumber. New york plumbing business made 100 billions last year|
Every pin had the phrase "New York Plumbing" followed by few words. Then I added few likes and repins to every pin (you can use many free bots available).. Once done..
4. Add comments randomly to the pins.. its not necessary to add it to every pin.. Also Make sure the comments have the keywords in them..
5. Now that you are ready with your board. Blast the board link and pin links with social bookmarks, wiki links, scrapebox comments and whatever you can think of.. Pinterest is a Super Authority Domain and its chances to get penalized is negligible..
And you rank!
PS: That's not the actual keyword I used. But I used same strategy for my client and he did get leads for his business. His keyword was high competition with 1000 Searches locally Pinboard was serving him as a mini-site to him. Pinterest has a trust value.
The method is easily scalable...
