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
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
The Budget: The average lifetime value of a customer is $450. You know that the average purchase is $35. The business makes 20% profit on all sales. Most returning customers buy once a month. Your current monthly sales are $16,000 with a slight increase when seasons change. A steady increase in sales over six months to a 15% increase by month six would mean a total sales increase of $8,400 over the six months and a total lifetime value of around $30,900. Spending $3,000 on the six-month organic marketing campaign would see a return on investment of 106%. The advantage of organic marketing is that it keeps working even after the campaign has ended. This means that the ROI would actually be higher.
The thing about SEO in 2018 is that Google changes its algorithms more than once a day! Reports say that the company changes its algorithms up to 600 times a year.

Search engine marketing is the practice of marketing a business using paid advertisements that appear on search engine results pages (or SERPs). Advertisers bid on keywords that users of services such as Google and Bing might enter when looking for certain products or services, which gives the advertiser the opportunity for their ads to appear alongside results for those search queries.
So just how much of the traffic that finds itself labeled as direct is actually organic? Groupon conducted an experiment to try to find out, according to Search Engine Land. They de-indexed their site for the better part of a day and looked at direct and organic traffic, by hour and by browser, to pages with long URLs, knowing that pages with shorter URLs actually do get a large amount of direct traffic, as they can be typed quickly and easily into a browser. The results showed a 50% drop in direct traffic, clearly demonstrating how all of these other factors come into play during the analytics process.
