First, I will show you a quick snapshot of the traffic uplift, which yielded an additional 400,000 unique visitors from organic search traffic on a monthly basis. Then I will explain to you the steps in which we took to get the client to this level. I have also tried to keep this quite general so everyone can adapt their own situation to this case study.
Click through rate: Except for high purchase intent searches, users will click on paid search listings at a lower rate than organic search listings. Organic listings have more credibility with search engine users. In one UK study, published by Econsultancy, only 6% of clicks were the result of paid listings. In another study, it was 10%. The important thing to remember is that click through rate varies by purchase intent. Organic rankings will get more click through rates for “top of funnel” keyword search queries.
The position of a link on a search results page is important. Depending on the search term, organic search results often make up only a small portion of the page. Since ads are at the top of the results page, on a device with a relatively small display -- such as a notebook, tablet or smartphone -- the visible organic search results may consist of only one or two items.
I agree with the point that a small or medium-sized business will have limits for budget and resources in generating brand search, but I wouldn't say that stops them from potentially producing huge growth there if they do something interesting/innovative etc. I can think of quite a few small to medium sized brands that have more name recognition than larger companies in their space. The challenge is that many of those brands are led by people who are very good at generating marketing and publicity - it's harder for small brands to be able to afford to pay for a top level consultant or agency.

For a long time, digital marketers summed up the properties of direct and organic traffic pretty similarly and simply. To most, organic traffic consists of visits from search engines, while direct traffic is made up of visits from people entering your company URL into their browser. This explanation, however, is too simplified and leaves most digital marketers short-handed when it comes to completely understanding and gaining insights from web traffic, especially organic and direct sources.

Check out the average CPC for some top industries. These are the costs of one click. Mind you, that’s a click that is not guaranteed to convert a customer. With paid campaigns, you have to keep optimizing and testing the ad creative to lower your CPC and increase your CTR. You can imagine that it takes a massive budget to even set a paid campaign in motion. And it requires just as much to keep maintaining it.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines[18][19][51] are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility,[52] although the two are not identical.
Clients turn to search engines because they really need a product or service. They have already created a need; it only remains to find a company that suits their interests. It is a medium that can easily encourage conversion, if the company offers what the customer is looking for; the visit will result in action by the customer, either a direct purchase, request for a quote, or more information for a later purchase.
New zero-result SERPs. We absolutely saw those for the first time. Google rolled them back after rolling them out. But, for example, if you search for the time in London or a Lagavulin 16, Google was showing no results at all, just a little box with the time and then potentially some AdWords ads. So zero organic results, nothing for an SEO to even optimize for in there.

The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.[1]
