Getting seen by people who are interested in your niche or brand helps you boost your brand’s visibility. Which indirectly affects the amount of business you get. Even if a lot of people are not immediately clicking on your ads, they may search for your product in the future. Either way, the paid ads will help immensely in terms of getting in front of your target audience and filtering out anyone who is not a part of it.
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.
Paid social can help amplify organic content, using social network advertising tools to target the audience. Using the rugby example, on Facebook you could target people who like other leading rugby fan pages. I recommend testing paid social campaigns to promote key content assets like reports and highlight important news/announcements. With a small budget you can quickly measure amplification impact.
The value of this that it is natural. In this day and age, we have become incredibly immune to advertising. People see it everywhere. We have been trained to unconsciously identify and ignore advertising. However, organic marketing provides value-first content to people who want to consume it. When people are searching or browsing for information about your products and services you want to be there to provide exceptional content.
So for the last 19 years or 20 years that Google has been around, every month Google has had, at least seasonally adjusted, not just more searches, but they've sent more organic traffic than they did that month last year. So this has been on a steady incline. There's always been more opportunity in Google search until recently, and that is because of a bunch of moves, not that Google is losing market share, not that they're receiving fewer searches, but that they are doing things that makes SEO a lot harder.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
