Sometimes considered to be a part of SEM, social media sites like Twitter, YouTube, Facebook, and Delicious have search fields and also pass authority to sites through links. Making sure your content and links are placed (where necessary) on these social media sites can increase your influence in user search engine queries. SMM is a rapidly growing area of Internet marketing but to discuss it further is beyond the scope of this Guide.
The challange is for SEO's then to tell this to the clients and not worry of loosing them. What to report on then, for GMB- impressions (this should decrease because I found on the maps that the link to website isn't always there!), GMB dashboard for views (a test showed stats on the GMB dashboard are incorrect) the suggested channels social, youtube don't fall under organic traffic

As pointed out, they are certainly not the same, but it might not be a bad idea to track and report on the direct traffic. If there has been outreach done and the company is mentioned in print with a URL, direct traffic (along with some search traffic on the URL or business name itself) is likely to go up. If your email newsletters are not tagged, they're likely to show up under direct traffic. Depending on your role, some of what you do under the greater SEO/inbound marketing role can show up under the direct traffic.

Social media is the easiest and most effective way to push out your SEO-based content. While the incoming links from your social media shares don’t have the same impact as authentic links from high-quality sites, they can influence your bounce rate and time-on-site engagement. If your content is good and people stick around to read it, those engagement metrics communicate value to search engines. Your goal should be to turn your best organic content into social media content so you can then encourage engagement and drive traffic back to your site.
● Collect conversion related data from your PPC campaign and use it to convert your organic search visitors better. Also, keywords that worked for you in PPC are best to optimize your website for, so using them for SEO purposes makes sense. Your PPC campaign will end, but the rankings you achieve for the same keyword will remain for quite some time.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
