Billions of people search the web every day. Search engine marketing (SEM for short) is how you can get your ads in front of these future customers where it counts: in premium spots on the first page of search results. You set your own budget and are charged only when your ad is clicked. This makes SEM an affordable way to reach more customers for businesses of all sizes — including yours.
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
I think for agencies as far as how we appear in organic search ourselves, we are definitely going to need to leverage all 3 of the solutions you talk about and agencies who haven't branded their products/services are going to have to do that and are going to have to also employ branding strategies. In addition, we have to optimize for other search ares like you say in your point #2 and we must look at optimizing existing content for voice search and answers/featured snippets like you say in point #3.

Not all businesses will have the need or even the budgetary resources to deploy paid marketing campaigns. However, every business needs to embrace organic marketing. It’s not an option. Here’s why. A marketing strategy built only on paid is shallow; it won’t help you to build an authentic connection with your customers. If all they see are ads – with no educational content, informational emails, or even engaging social media posts to complement those ads – you lose the mindshare of your customers in two ways:
I don’t know how much time it took to gather all this stuff, but it is simply great I was elated to see the whole concept related (backlinks, content strategies, visitors etc) to see at one place. I hope it will be helpful for the beginners link me. I recently started a website, also I’m newbie to blogging industry. I hope your information will helps me a lot to lead success.
Movies: a great movie experience gets people talking about it + public relations (TV show appearances or for example, People naming Gwyneth Paltrow the most beautiful woman in the world when Iron Man 3 came out). Advertising just helps to spark word of mouth. The point is to spark word of mouth, because people don’t often see movies alone. They take their family, friends or a date. Those people will base their decision either purely on their recommendation, or by going online and looking for a preview or reading about it, which is also organic marketing. The difference is this: paid advertising will only get the movie so far; organic marketing is what will multiply sales. Money only buys the ad spot, it doesn’t guarantee a return on that ad; the quality of the ad and the storytelling in it is what makes it effective or not.

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.

PPC gives you the ability to fix your daily budget depending on how much you’re willing to spend. And since you can start off with a small amount, you don’t have to put a heavy investment at stake before testing the waters. Once you know a certain campaign is giving you a good return on investment, you can ramp up your budget and increase your ad spendings without worrying about incurring losses.
Back end tools, including Web analytic tools and HTML validators, provide data on a website and its visitors and allow the success of a website to be measured. They range from simple traffic counters to tools that work with log files and to more sophisticated tools that are based on page tagging (putting JavaScript or an image on a page to track actions). These tools can deliver conversion-related information. There are three major tools used by EBSCO: (a) log file analyzing tool: WebTrends by NetiQ; (b) tag-based analytic tool: WebSideStory's Hitbox; and (c) transaction-based tool: TeaLeaf RealiTea. Validators check the invisible parts of websites, highlighting potential problems and many usability issues and ensuring websites meet W3C code standards. Try to use more than one HTML validator or spider simulator because each one tests, highlights, and reports on slightly different aspects of your website.
If you check out some of the suggestions below this though, you're likely to find some opportunities. You can also plug in a few variations of the question to find some search volume; for example, I could search for "cup of java" instead of "what is the meaning of a cup of java" and I'll get a number of keyword opportunities that I can align to the question.
Paid or sponsored ads usually charge you for a click, while SEO doesn’t require you to pay for impressions or clicks. But do keep in mind that quality SEO isn’t exactly free. Depending on the target market you are in, you will have to invest time and money into getting the desired results. And if you’re not an SEO expert, then you would have to work with a reputable SEO company do it for you.

Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
