Creating the link between SEO and PPC represents an integral part of the SEM concept. Sometimes, especially when separate teams work on SEO and PPC and the efforts are not synced, positive results of aligning their strategies can be lost. The aim of both SEO and PPC is maximizing the visibility in search and thus, their actions to achieve it should be centrally coordinated. Both teams can benefit from setting shared goals and combined metrics, evaluating data together to determine future strategy or discuss which of the tools works better to get the traffic for selected keywords in the national and local search results. Thanks to this, the search visibility can be increased along with optimizing both conversions and costs.[21]
Beyond organic and direct traffic, you must understand the difference between all of your traffic sources and how traffic is classified. Most web analytics platforms, like Google Analytics, utilize an algorithm and flow chart based on the referring website or parameters set within the URL that determine the source of traffic. Here is a breakdown of all sources:

Organic Search: Organic search results are the listings of Web pages returned by the search engine’s algorithms that closely match the search string of keywords. Marketers use SEO and content assets to get high search engine rankings. The goal is to be on the first page and then move into the top three rankings for specific keywords. That’s because the advantages of organic search are dependent on visibility. The higher the ranking the more pronounced the advantages. They all but disappear if your listing is not on the first page.

People find their way to your website in many different ways. If someone is already familiar with your business and knows where to find your website, they might just navigate straight to your website by typing in your domain. If someone sees a link to a blog you wrote in their Facebook newsfeed, they might click the link and come to your website that way.
People are more receptive to hearing these marketing messages because they are more natural and organic. They’re not paid for and stuffed in their faces through interruption marketing. An indelible experience has intrinsic emotional and psychological value, as people enjoy it. They then feel emotionally compelled to share their experience with others that they have a close relationship with as part of relating, so that they can share in the emotional experience too. This is done through conversation, phone, text, email, Facebook shares, Tweets, and the like.
When you’re trying to drive traffic to your website, it’s crucial that you get only relevant people to see your listing. Or else there’s no use getting a ton of visitors. When you’re doing SEO, you may or may not get the right people to visit your website. But it’s not the same with PPC ads. Your ads are laser targeted towards users who are actually searching for your product or service.
Google's search engine marketing is one of the western world's marketing leaders, while its search engine marketing is its biggest source of profit.[17] Google's search engine providers are clearly ahead of the Yahoo and Bing network. The display of unknown search results is free, while advertisers are willing to pay for each click of the ad in the sponsored search results.
Plan your link structure. Start with the main navigation and decide how to best connect pages both physically (URL structure) and virtually (internal links) to clearly establish your content themes. Try to include at least 3-5 quality subpages under each core silo landing page. Link internally between the subpages. Link each subpage back up to the main silo landing page.
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.

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.

Not every single ad will appear on every single search. This is because the ad auction takes a variety of factors into account when determining the placement of ads on the SERP, and because not every keyword has sufficient commercial intent to justify displaying ads next to results. However, the two main factors that Google evaluates as part of the ad auction process are your maximum bid and the Quality Score of your ads.
Let’s assume that your goal is customer acquisition. You know you’ve acquired a customer when you make a sale. So, you’d set up a sales conversion goal. To do that, click on “New Goal.” In the goal setup section, you can either select “template” or “custom.” Custom gives you more flexibility, so go with that option. Go on to the “goal description.” This is where you define your goal by naming it and selecting the type. For customer acquisition, you want to select “Destination.”
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]
