Having large groups of content that all revolve around the same topic will build more relevance around keywords that you're trying to rank for within these topics, and it makes it much easier for Google to associate your content with specific topics. Not only that, but it makes it much easier to interlink between your content, pushing more internal links through your website.
I'm thinking about "less to do" (linking-social media) sites with physical products … Amazon and other merchants. And adding a PPC campaign instead of using social media and constantly toiling away building links and writing articles. Is there an easy way to get sites like this to rank while profiting with some paid traffic? Your opinion on this dilemma .. SEO vs PAID traffic or both would be much appreciated.

The HTML tag is meant to be a concise explanation of a web page’s content. Google displays your meta description beneath the page title in their organic results. While meta descriptions aren’t as important as page titles in your Google ranking, they do play a big role in getting clicks from users. People read descriptions as a preview of your page and use it to determine if your content is worth visiting. You should keep your meta descriptions to under 150 characters since Google won’t display text beyond that. You should also include target keywords in your text, since any words matching a user’s search query will be displayed in bold.
Look to successful brands to see how they keep customers engaged. Do you need to constantly update content, as Home Depot does with its seasonal DIY tips? Or do you need to position yourself as a lifestyle brand, following in Red Bull’s footsteps by running a series of videos on YouTube? Whatever method you adopt, it’s important to have some quantifiable way to measure how successful you are, so keep your ultimate goal in mind as you evaluate your return on investment.

Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
