Search engine marketing’s greatest strength is that it offers advertisers the opportunity to put their ads in front of motivated customers who are ready to buy at the precise moment they’re ready to make a purchase. No other advertising medium can do this, which is why search engine marketing is so effective and such an amazingly powerful way to grow your business.

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]
Understanding the working mechanism of social algorithms is not a piece of cake. The algorithm for each social platform works differently. For instance, on Facebook, a core factor that affects the rankings of a post is its relevancy score, whereas on YouTube the total watch time of the video per session decides whether a video enters a ‘Recommended Video’ section or not.
Now, it’s important to emphasize that the term “organic marketing” doesn’t mean that no money is spent. You’re still going to invest in your marketing strategy and any related software ( Hubspot for inbound, MailChimp for email lists, Buffer for scheduling social media posts, and the like). Rather, organic means you’re not paying to boost the specific post itself.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
