Most real businesses sell real products and they really do not want adverts for rival products showing on their website. Not having 'ads' is a bonus.
If you live in a Silicon Valley bubble where the 'customer is the product' and all you have to sell is advertising space then you might not understand this.
Adding images to this website does not necessarily undermine the 'audit' metrics. Clearly this has to be done with sensibly sized images otherwise those metrics will be affected negatively.
Small to medium sized real businesses do not necessarily need Google Analytics with people on the payroll to troll the rest of the company with petty 'SEO demands'. If a company has established relationships with distributors or if products are supplied on an 'OEM' basis to a handful of partners then the website need be no more than a glorified 'contact us' page.
Server side analytics are fine for such an internet presence. In some ways better as there is no need to have a silly 'cookie' notice.
You have a very narrow idea of business value if it is all about stalking your potential customers and ramming adverts that they did not want down their eyeballs, wasting their time and bandwidth in the process.
