Before you dig into some of the more technical ways to improve SEO ranking, always remember that writing compelling, high-quality content that attracts interest and compels visitors to share it and link back to it is vital. Good content has the best chance of being viral content, and Google rewards content virality heavily in its rankings algorithm.
And then when it comes to actually, ‘OK, so now I’m engaged in these groups, now what?’ What I always recommend doing is taking the conversation offline. So reaching out to the people who you responded to in the group via InMail, or taking it to email, or phone even, and really making that be the place where you do some of the investigating to figure out if they’re a good client fit for you.
In order to optimize your SEO results, it’s important to measure the impact of your efforts on web site traffic and lead/sales generation. Google Webmaster Tools can give you important insight into how your site is functioning and identify potential errors you should correct. An analytics tool such as Google’s Universal Analytics is helpful for measuring changes in search traffic as well as tracking visitors interactions with your web site that are a direct result of SEO. Marketing automation tools and call tracking tools can help you tie leads and sales back to SEO.
