In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[21] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
Marketing strategies have evolved over the course of time. Back then, organic search, when hit right on the spot, would give you the right amount of exposure that your business needs. Apart from that, it used to give you a better deal at a lower cost compared to when you do pay per click. However, with the digital age coming in and small businesses are starting to become popular, they are now mostly leaning towards the fast-paced wonders of paid search.
The Featured Snippet section appearing inside the first page of Google is an incredibly important section to have your content placed within. I did a study of over 5,000 keywords where ranked on page 1 and there was a Featured Snippet being displayed. What I found was that when was ranking in the Featured Snippet, the average click-through rate to the website increased by over 114%.
It’s not going to run up your grocery bill.

Traffic data is a great way to take the temperature of your website and marketing initiatives. When you are writing and promoting blog content on a regular basis, you can use traffic data to track results and correlate these efforts to actual ROI. Be sure to look at traffic numbers over long-term intervals to see trends and report on improvement over time.  

Page and Brin founded Google in 1998.[22] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[23] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[24]

BrightEdge research supports that a blended approach is best for delivering high performing content. Not only will combining organic and paid search increase website traffic, but it will offer a bigger return on the investment.
