If you are using a niche account, then it will be essential that you use power keywords in the description of your profile.

Board Titles are also critical and should be power keywords and phrases, not cute, clever or unusual names that will not be found in a search. Board descriptions offer a lot of valuable marketing space to share your message about your brand, but it should be relevant to the board content to avoid looking like a spammer.

Tests prove that pin image names show up in the search results. So when creating or renaming images to pin, it is important to be sure to use your brand and power keywords to describe them [yourbrand-healthy-energy-drink-free-sample] (something like that…lol)

Offer other valuable marketing space to share your brand/products/services message, but it should be relevant to the pin.
