Years ago I started monetizing my websites to a modest degree, using Google AdSense. I never expected to make big money, and I haven’t, for a number of reasons:
I try to emphasize content, not ads. I want my ads to be unobtrusive.- I will never subject my visitors to obnoxious ads that popup, pop-over, pop-under, pop-sideways, pop-anything. I hate those things.
- I choose site topics that are of interest to me, not high-paying niches like mortgages or personal injury lawsuits.
- My sites are not popular enough to generate much income.
I use a single ad per page, unobtrusively positioned in the right margin, away from the content. I just hoped to pay for my indulgence in web dabbling – i.e. to cover hosting and domain registration fees. I did better than that for quite a while, until I incurred The Wrath of the Great Google God. Since Google libelously branded me a hate monger and copyright pirate and demonetized my sites my pocketbook suffers a bit but my integrity is intact and my conscious clear. Eff you Google.
In another post I give my point of view on the new AdSense Auto-Ads.
