If you are an expert in something then provide that expertise to journalists via the service HARO.
On HARO you state your expertises, and journalists who are writing articles on the topic reach out to you to "ask an expert" so they get statements they can use in their articles. And you get quoted, and a link to your site - everybody wins. Many startups got mentions in top publications this way.
Quora, a trendy question-and-answer site, gets a lot of traffic, esp. from search engines. Providing high quality answers therefore often pay off (including a link to your site is allowed - if disclosed).
Also: you position yourself as expert in a certain field and others (potential business partners) will start reaching out to you.
If you like Solutionbay then others will too and it will grow... think long-term and post your great solution(s) now - the earlier you post them, the more likes they will get in the long-run, and the higher they will rank.
