Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
The objective of (SEM) is to drive traffic to your website with the intent of converting those visitors into customers. With SEM, it is important to have your business site listed near the top of the search engine rankings since very few internet users will actually look at search results beyond the first couple of pages. SEM can be divided into two categories: organic and paid. Both are important.
Content is one of the 3 main Google ranking factors. As a matter of fact, having a blog can help you get your content indexed faster. An active blog – relying on qualitative and insightful content, and backed by authoritative links – will help you improve your rankings and thus your organic traffic. Also, long-form copies (above 1200 words) tend to rank higher and be crawled more often.
That means it takes time, but the results are long-lasting. Once you establish search engine visibility, it will serve your business for years after it’s implemented. That’s not to say that there isn’t any maintenance involved in an organic traffic strategy. The SEO landscape is ever changing. You can’t just “set and forget” your traffic system. The algorithms and ranking factors evolve. You have to keep on top of these changes to maximize your results. With all that said, an organic traffic strategy is as close as you’ll get to a traffic system on autopilot. And just another reason why organic traffic is important.
In 2014, BrightEdge published research that showed that 51% of channel traffic came from organic search and that it was far and away the largest channel. In the intervening years there were significant search algorithm changes that dramatically altered the layout and ranking of the search engine results pages and saw an increase in the space taken by Local, Videos, Images, Ads, and Quick Answers.
Look at the different search engines (sources) that drive traffic to your site to determine where you want to invest your resources. For example, if you're getting an overwhelming amount of visitors and revenue from a particular search engine, that's an obvious source of profitable traffic and an area in which you might want to make further investment; but you might also find another search engine that delivers only a few visitors, but ones who represent a very high Per Visit Value. In this latter case, you might want to increase your spend in that area to drive more of those high-value visitors to your site.
So just how much of the traffic that finds itself labeled as direct is actually organic? Groupon conducted an experiment to try to find out, according to Search Engine Land. They de-indexed their site for the better part of a day and looked at direct and organic traffic, by hour and by browser, to pages with long URLs, knowing that pages with shorter URLs actually do get a large amount of direct traffic, as they can be typed quickly and easily into a browser. The results showed a 50% drop in direct traffic, clearly demonstrating how all of these other factors come into play during the analytics process.
Another ethical controversy associated with search marketing has been the issue of trademark infringement. The debate as to whether third parties should have the right to bid on their competitors' brand names has been underway for years. In 2009 Google changed their policy, which formerly prohibited these tactics, allowing 3rd parties to bid on branded terms as long as their landing page in fact provides information on the trademarked term. Though the policy has been changed this continues to be a source of heated debate.
It is important to target keywords that your target consumer is likely to search for while looking for the product or service that you offer. For example, if you are an accounting firm located in Miami you would not want to target a general keyword such as “accounting firm.” Not only is it a very difficult keyword, but also you will be attracting visitors from all over the globe. Instead, you would want to target a more precise keyword such as “accounting firm in Miami” or “Miami accounting firm.”
Incidentally, according to a June 2013 study by Chitika, 9 out of 10 searchers don't go beyond Google's first page of organic search results, a claim often cited by the search engine optimization (SEO) industry to justify optimizing websites for organic search. Organic SEO describes the use of certain strategies or tools to elevate a website's content in the "free" search results.
That said, ground-up marketing works because it’s work. There’s no substitute for careful attention to your website’s content and careful curation of your business’s social media presence. Paid ads can be an effective tool within a high-budget marketing strategy, but if the consumer arrives at your website and doesn’t find what they’re looking for, how is that investment working for you? It’s not. If a sponsored tweet draws them in but a discrepancy in expectation chases them away, what’s the benefit there? It’s absent. Organic marketing is a long process, but ultimately it will yield more authentic customer engagement and more accurate SEO.
You can also use organic to increase audience engagement with your content. For example, let’s say you’re a ticketing website for sporting events and you know that some of your followers are rugby fanatics. If you have a new blog interviewing Dylan Hartley (current England captain), then it makes sense to personally contact them (or at least key influencers) via their preferred social network and tell them about the blog, and ask them to comment/share. It’s personal and increases the chance they’ll see/read your content.
This is the number of views that you can test each month on your website.It's up to you how you choose to use them, either by allocating all the views to one test or to multiple test, either on one page or on multiple pages. If you have selected the 10.000 tested views plan and you run an experiment on your category page which is viewed 7000 times per month, then at the end of the month 7000 is what you'll be counted as tested views quota.
