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]
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
Most online marketers mistakenly attribute 100% of a sale or lead to the Last Clicked source. The main reason for this is that analytic solutions only provide last click analysis. 93% to 95% of marketing touch points are ignored when you only attribute success to the last click. That is why multi-attribution is required to properly source sales or leads.
PPC advertising is a method of advertising on search engines like Google and Bing. As mentioned earlier, with PPC ads, you pay each time that ad is clicked on. PPC ads also exist on social media platforms like Instagram and Facebook as well. However, if you're going to engage in PPC advertising, it's important that you determine conversion rates by using tracking pixels.
Achieving video marketing success is sometimes seen as expensive and hard to do. Content creators are often disappointed with the amount of effort it takes to produce an online video versus the online exposure and visibility that it actually receives. What if your video could appear extremely high in the search engines and thousands of views could be obtained for an extremely low price point?
There are ten essential types of marketing that can be done online. Some of these can be broken down into organic marketing and others can be categorized as paid marketing. Organic, of course, is the allure of marketing professionals from around the planet. It's free and its unencumbered traffic that simply keeps coming. Paid marketing, on the other hand, is still a very attractive proposition as long as the marketing pays for itself by having the right type of offer that converts.
Probably the most well-known Integrated Vertical Search is  Google’s “Universal Search” –  although all of the major search engines have now adopted similar search formats. This is the practice of incorporating different types of results in the Search Engine Results Pages (SERPs), such as news releases, images, videos, etc., depending on the query.  This was a game changer for SEO when it was first introduced – it became necessary to create and optimize many different types of content because they all show up on SERPs. The term for this comprehensive approach is referred to as Digital Asset Optimization (DAO).
