It takes skill to drive and convert traffic. If you do it yourself, it takes a significant time investment. If you outsource it, it takes a considerable monetary investment. Either way, you need resources. And you’re doing all this in a highly competitive space. Driving organic traffic is no longer just about deploying keywords. SEO is a lot more nuanced and complex than just targeting keywords. You have to consider different keyword types, the search intent of the user and the stage of awareness of your prospects. It takes time to see results.
With organic search, you don’t have to outspend your competitors to outrank them. Your competitors can’t recreate the content experience that you use to drive organic traffic.  This one is major. PPC is easy to replicate and reverse engineer. Many spy tools allow you to dissect paid campaigns to see what’s working and what’s not. You can get insight into what ad creatives generate the most clicks.
It means that every piece of content that leads searchers to you is extending your brand equity. Not only that, you’re creating multiple touch points, so potential customers have every opportunity to discover your business. It takes on average of 6-8 touch points with a brand before someone becomes “sales-ready.” Too many? Well, for some industries, it’s way more. One woman’s car-buying journey took 900 digital touch points spanning three months.
The term “organic” refers to something having the characteristics of an organism. Although black hat SEO methods may boost a website’s search engine page rank in the short term, these methods could also get the site banned from the search engines altogether. However, it is more likely that readers will recognize the low quality of sites employing black hat SEO at the expense of the reader experience, which will reduce the site’s traffic and page rank over time.

Of course, there is a lot more that needs to be considered but this is a simple example of how all of these things work together. I would recommend having no less than one page for each step of the organic marketing plan if you are a small business. The larger your business the more planning that you should do. If you do not think through all the details you will miss something that will cost you.
Hubspot found that their articles up to 2500 words drive the most traffic. Similarly, posts with more than 2500 words generated more social shares and links. Naturally, it takes some investment to create that quality of content. The key is to come up with evergreen ideas. This way, your investment will more than pay for itself because your content will be serving your business goals years down the line. Put people first. The thing about search engines and how they rank content? It’s unpredictable. But one thing will remain constant. The job of a search engine is to connect users with the most relevant and useful information. If your content serves that purpose, you don’t have to fear algorithm changes.
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.

Organic traffic is the primary channel that inbound marketing strives to increase. This traffic is defined as visitors coming from a search engine, such as Google or Bing. This does not include paid search ads, but that doesn’t mean that organic traffic isn’t impacted by paid search or display advertising, either positively or negatively. In general, people trust search engines, and sayings such as “just Google it” reinforce that humans are tied to the search engine. Thus, paid search, display, or even offline campaigns can drive searches, which may increase organic traffic while those campaigns are running.

Search engines: Google vs. Bing. Google was the first search engine that provided better search results and people told others about it so it spread virally and became a verb “Google it”, whereas Bing is trying to buy it’s way into the market, doing ads, deals with Facebook and Yahoo, etc. Most people weren’t asking for a 2nd, “me-too” search engine, the first one solved their search pain and continues to do so, so trust was built and people have remained loyal to it.
Another tip you can use is just reach out to the prior agency and say something like the following: “We realise you were using link networks for our website which has resulted in a Google penalty and loss in business. Can you please remove my website from any link network you have built?”. If the prior agency is decent, they will remove the links from the network.
Thanks for the comment Slava good too see your team is on top of things and happy you liked the post. The website in the case listed was a client who has taken on an agency who was doing lower quality SEO work which was affecting the site such as the huge link network and a strategy which only revolved around mainly head terms. We saw no long tail integration from the old agency's strategy, so we were able to yield great results to begin with. The clients site has 100's of high quality articles which we were able to re optimize and update as noted. Further to this they had a large index of high quality pages to work from. Sure enough the points listed above were key elements to a far wider strategy which could be 100's of points. I just wanted to include some of the biggest wins and easy to implement points.  
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots. When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[46]

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.

The term was first used by Internet theorist John Kilroy in a 2004 article on paid search marketing.[citation needed] Because the distinction is important (and because the word "organic" has many metaphorical uses) the term is now in widespread use within the search engine optimization and web marketing industry. As of July 2009, "organic search" is now common currency outside the specialist web marketing industry, even used frequently by Google (throughout the Google Analytics site, for instance).
