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
There are also a few more similarities. All of these marketing methods are measurable to an extent never seen in any other media. Every click can be measured – where and when it came – and followed through to the conversion, the sale and the lifetime customer value.  This feedback loop creates optimization opportunities that can create huge incremental improvements in your SEM campaigns.

With the development of this system, the price is growing under the high level of competition. Many advertisers prefer to expand their activities, including increasing search engines and adding more keywords. The more advertisers are willing to pay for clicks, the higher the ranking for advertising, which leads to higher traffic.[15] PPC comes at a cost. The higher position is likely to cost $5 for a given keyword, and $4.50 for a third location. A third advertiser earns 10% less than the top advertiser, while reducing traffic by 50%.[15] The investors must consider their return on investment and then determine whether the increase in traffic is worth the increase.

Regarding Link Detox, links it diagnoses as Toxic are generally fine as they're either not indexed by Google or have malware/viruses/etc., but I recommend a manual review of any diagnosed as Suspicious. I used it recently to get started cleaning up our backlinks and some legit sites and blogs were under Suspicious simply because they didn't have many links pointing to them.
Internet marketing professionals refer to search that isn’t organic as paid search. Instead of organically, or naturally, reaching the top of the search results for a particular keyword, businesses can pay to get noticed. So, paid search is a bit like doing a local endorsement, TV ad or radio spot—but for the internet. When a consumer types in a search term that you’ve incorporated into your campaign, your ad will show up at the top of search page results, above the organic results. Sometimes, your ad may appear in the sidebar. Only if the consumer clicks on your ad do you pay anything.
Search engines: Google vs. Bing. Google was the first search engine that provided better search results and people told others about it so it spread virally and became a verb “Google it”, whereas Bing is trying to buy it’s way into the market, doing ads, deals with Facebook and Yahoo, etc. Most people weren’t asking for a 2nd, “me-too” search engine, the first one solved their search pain and continues to do so, so trust was built and people have remained loyal to it.
The Featured Snippet section appearing inside the first page of Google is an incredibly important section to have your content placed within. I did a study of over 5,000 keywords where ranked on page 1 and there was a Featured Snippet being displayed. What I found was that when was ranking in the Featured Snippet, the average click-through rate to the website increased by over 114%.
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.
