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.
Lynn, it is so true that just talking about a brand in a blog post gets you noticed. I did a blog post a few years ago on a toy and mentioned that is was on the Parenting Magazine top 10 list. I did not link to the magazine, I just mentioned it and they sent me a free one year subscription to their magazine, and a whole box of coloring books for my kids. It wasn't monetary, but at least the company acknowledge that I referenced them.
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review. Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links in addition to their URL submission console. Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click; however, this practice was discontinued in 2009.
The advantage of paid search is that you can have your website listed on the first pages in a prominent spot on Google and other search engines. However, showing up is only part of the process. You need to create an ad that not only leads to clicks, but to sales or whatever result you're looking for. If you don't know what you're doing, it's possible to write an ad that people are drawn to and click on, however, you don't make sales. Since you pay per click, and clicks can add up quickly, you can lose money.
There are many different updates happening in the SEO world from time to time. This is to ensure that the users are seeing only the best search engine results against their queries. However, due to such frequent changes, your website’s position in the organic search results can be affected. And sometimes, you may lose ranking that you built over a period of time.
H1 and H2 title tags are names for the two most important types of titles in your website. H1 tags are your main titles – usually large or bolded on a website, and at the top – and H2 tags are secondary titles that clarify your main title, or might be the titles to different page sections. To utilize these sections effectively, you can use the format “Business | Keyword” as your H1 tag. For example, if my business name was “Emily’s Images” and my keyword was “Atlanta wedding photography,” my title would look like “Emily’s Images | Atlanta wedding photography”.
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 
Second thing, optimizing across additional platforms. So we've looked and YouTube and Google Images account for about half of the overall volume that goes to Google web search. So between these two platforms, you've got a significant amount of additional traffic that you can optimize for. Images has actually gotten less aggressive. Right now they've taken away the "view image directly" link so that more people are visiting websites via Google Images. YouTube, obviously, this is a great place to build brand affinity, to build awareness, to create demand, this kind of demand generation to get your content in front of people. So these two are great platforms for that.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
