This topic seems actually quite controversial. Google answered the question by what could be taken as a denial. But their answer was kind of open to interpretations. And on the other hand, there are studies (one of them from Moz) that showed linking out has an impact. So, how can you be so assertive? Is it something that comes out from your own experiments?
Many page owners think that organic reach (the number of unique individuals who see your post pop up in their news feeds) is enough to make an impact. This was true in the first few years of Facebook but is no longer the case. Facebook, and many other social media networks is truly a pay-to-play network. Facebook, Twitter, Instagram, and LinkedIn are all on algorithmic feeds, meaning posts are shown to the user based on past behavior and preferences instead of in chronological order. Organic posts from your Facebook page only reach about 2% of your followers, and that number is dropping. Facebook recently announced that, in order to correct a past metrics error, it is changing the way it reports viewable impressions, and organic reach will be 20% lower on average when this change takes effect.
Novelty wears off. Even if people aren’t getting sick of your ads, your product itself will become less revolutionary over time. When Casper launched, a direct-to-customer mattress-in-a-box company was a hot new take on the traditional sleep industry. Now there are so many competitors that the idea of a mattress showing up at your door in a box just isn’t as exciting.
To drive instant traffic to your website: Unlike organic social marketing, paid social ads instantly deliver results. The moment your ad goes live on social channels, you will get to see a large number of visitors on your web pages. Paid social ads are therefore ideal when you are planning to make a new announcement or if you are launching a new product/service for your brand.
For example, you may repurpose your blog content into a different form to satisfy the needs of your social media audience. You may decide to put more resources into email marketing as a traffic driver. You may tighten up your brand story because you want your messaging to be more congruent across all customer touchpoints. All these marketing tasks are tied to organic traffic. And they all have a substantial impact on your bottom line.
BrightEdge research supports that a blended approach is best for delivering high performing content. Not only will combining organic and paid search increase website traffic, but it will offer a bigger return on the investment. Take Retail, Technology and Hospitality industries, for example — organic and paid search combined make up more than two-thirds of their total revenue.
