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.
This is one of the more apparent benefits of organic search traffic. If your website ranks for a relevant keyword, you’ll enjoy regular targeted traffic. This consistent flow of traffic will open the floodgates for new leads and customers. That alone is a sweet deal. But here’s the thing about an organic audience: You have no choice but to create a rich content experience.

Remember that users enter search words into search engines based on their interest. The matching keywords and phrases you choose for your campaigns help determine if your ad will display when users search online. But be aware, other advertisers may also be using the same keywords. That creates competition with your ad campaign. What can you do to win? One solution is keyword bidding.
Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results.[citation needed] The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.[citation needed]
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
