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.
Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate search engine optimization (SEO), which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings.
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective like paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM), is practice of designing, running, and optimizing search engine ad campaigns. Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to PageRank visibility as most navigate to the primary listings of their search. A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate. In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public, which now shows a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops as shown in by StatCounter in October 2016 where they analysed 2.5 million websites and 51.3% of the pages were loaded by a mobile device . Google has been one of the companies that have utilised the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
Clients often ask me the difference and I give them a simple answer that normally puts an end to the conversation and their questions, much like the answer shane thomas gave, but less detailed. Direct is people putting in your url in the top and organic is people searching for you. Here is an example: If I want to buy a book i type in amazon.com (direct traffic) but if i forgot where to buy a book online i search for "where to buy a book online" which directs me to amazon.com (organic traffic). When i explain it like this, a light bulb goes off and they understand. Hope that helps.
The response rate here was huge because this is a mutually beneficial relationship. The bloggers get free products to use within their outfits (as well as more clothes for their wardrobe!) and I was able to drive traffic through to my site, get high-quality backlinks, a load of social media engagement and some high-end photography to use within my own content and on product pages.
Local SERPs that remove almost all need for a website. Then local SERPs, which have been getting more and more aggressively tuned so that you never need to click the website, and, in fact, Google has made it harder and harder to find the website in both mobile and desktop versions of local searches. So if you search for Thai restaurant and you try and find the website of the Thai restaurant you're interested in, as opposed to just information about them in Google's local pack, that's frustratingly difficult. They are making those more and more aggressive and putting them more forward in the results.
