Essentially, what distinguishes direct from organic traffic today is tracking. According to Business2Community, direct traffic is composed of website visits which have “no referring source or tracking information.” A referring source can be a search engine, or it can be a link from another website. Direct traffic can include visits that result from typing the URL directly into a browser, as the simple definition suggests.
Additionally, there are many situations where PPC (a component of SEM) makes more sense than SEO. For example, if you are first launching a site and you want immediate visibility, it is a good idea to create a PPC campaign because it takes less time than SEO, but it would be unwise to strictly work with PPC and not even touch search engine optimization.
While there are several HTML tagging techniques that improve a page’s Google SEO results, creating relevant page content is still the best way to rank high. A big part of content creation is your use of targeted keywords. You should include important keywords in your first 50 words, since early placement can be a signal of relevance. And while you should never repeat keywords too often at the expense of good writing, you should repeat keywords in your content two or three times for short pages and four to six times for longer pages. Also, you may wish to use some keyword variation in your content – such as splitting keywords up – as this could potentially improve your ranking.

Search engine optimization (SEO) campaigns generate organic traffic. The goal of SEO is to improve website ranking for relevant keywords. You want your website to show up on the first page of organic search results – ‘organic’ refers to the middle section of results you see in search engines – for what you’re selling, and you’d probably be considered super human if you did that without organic SEO.
Search engines reward you when sites link to yours – they assume that your site must be valuable and you’ll rank higher in search results. And the higher the “rank” of the sites that link to you, the more they count in your own ranking. You want links from popular industry authorities, recognized directories, and reputable companies and organizations.
Often the line between pay per click advertising and paid inclusion is debatable. Some have lobbied for any paid listings to be labeled as an advertisement, while defenders insist they are not actually ads since the webmasters do not control the content of the listing, its ranking, or even whether it is shown to any users. Another advantage of paid inclusion is that it allows site owners to specify particular schedules for crawling pages. In the general case, one has no control as to when their page will be crawled or added to a search engine index. Paid inclusion proves to be particularly useful for cases where pages are dynamically generated and frequently modified.
In order to quickly identify the correct content and websites that will meet their needs almost all users will use a search engine such as Google. Typing a query into a search engine will generate a set of results that are a combination of paid and organic search listings. The user can then choose the most relevant link from these results or search again if the results are not helpful.
‘There’s really two core strategies I always recommend. The first is looking after prospecting in groups. This one is a big one because I think this is one of the single best ways for sales and marketing to drum up new business on LinkedIn. But the caveat is I’ve also seen this go horribly wrong. And without getting into too much detail, there’s a few recommendations I have to avoid some of those pitfalls.
Organic is different. Matching keywords to user intent means you may be present in many searches. The user may find you consistently, and once they get to your site, they are more likely to stay. Organic users are still your best long-term customers. In my experience, they have lower bounce rates and more pages visited, and they are more likely to return.
