Aggressive "answer" boxes. So you search for a question, and Google provides not just necessarily a featured snippet, which can earn you a click-through, but a box that truly answers the searcher's question, that comes directly from Google themselves, or a set of card-style results that provides a list of all the things that the person might be looking for.
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.
Keyword difficulty is a number that lets you know how difficult it will be to rank for a certain keyword. The higher the number, the more difficult it will be to rank on that keyword. There are a few sites online that will tell you keyword difficulty of a word or phrase. Record these numbers in your Excel document or Google Sheet that you made earlier.
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.
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.
That's why it's necessary to always stay abreast of developments in the SEO world, so that you can see these algorithm updates coming or you can determine what to do once they’ve been released. The WordStream blog is a great resource for SEO updates, but we also recommend Search Engine Land and Search Engine Roundtable for news on updates. Glenn Gabe of G-Squared Interactive is also a great resource for analyzing the causes and impact of algorithm updates.
