In 2007, Google announced a campaign against paid links that transfer PageRank.[29] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat nofollowed links in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[30] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated Javascript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and Javascript.[31]
One of the things that can slow-bleed the traffic from your site is the quality (or lack thereof) of the content you publish on your site. Previous Google updates like Panda have already been released specifically to deal with the issue of low-quality content on websites. Long story short: Panda intended to stop sites with bad content from appearing in the search results.
This is a crucial area. If you do not have schema markup and rel="author", you are costing your business money. It is as simple as that. As an example, say I want to make spaghetti (pasta) for dinner I search for “Spaghetti Recipe” and instantly I see some great markup in play, but one competitor has no markup and no rel="author" they are losing business in my eyes. Wouldn't you agree?.
Using this data can help you identify additional “buyer” keywords to target and what keywords to stop targeting. Keyword research, content marketing, and link building are things that you need to constantly be doing, even when you reach the top of the search rankings. Many businesses think that they can slow down these efforts once they reach the top, but easing up on your SEO strategy will see your competition take over the top position if you are not continually improving your search engine optimization effort.
This means that each organic search visit is worth $7.35. Chances are, you’ll spend WAY less than that to generate that one visit. How’s that for some rock-solid ROI? You can get even more specific with this by looking at the organic search traffic for a particular keyword. By extension, you can calculate the ROI of that keyword. You can begin to see how this can ramp up your SEO game.
Using organic search data through Data Cube you can make your PPC campaign even stronger. You can research keywords that have the highest traffic and use the BrightEdge Recommendations engine to learn the types of sites that people are most likely targeting with specific queries. You can then create content for your PPC campaigns armed with this insight, positioning yourself well for paid search success.
The second is to really avoid promoting yourself, or your services, or your business, in these groups when you first join them. Like with any social network, you really need to build trust. And the best way to do that is to simply engage with the content that’s already there. Start replying and making genuine comments about the content being posted by people that could be prospects for you.

Organic is what people are looking for; the rest of these simply put things in front of people who may or may not be seeking what you offer. We know that approximately X number of people are looking for Y every day. So if we can get on front of those people, we have a much greater opportunity to create long-term relationships and increase our overall ROI.
