So how long is good content going to hold up the monetization of web sites?
In my case twelve years and I haven't written anything new for nearly ten years.
The theory that you "must" continually add new content is a total fallacy in my case.
Yes, I have earned very considerable sums of money over those twelve years.
The biggest mistake newcomers make is getting hung up on monetising a site. Forget about that for twelve months IMHO.
When I first started out it was to help people with answers to questions asked on a technical forum where it wasn't exactly easy to fully explain in emails. I used free web space which was part of my ISP package.
Then as I added more lectures and topics people started linking. Mr. Yahoo made me "the featured site of the week". Educational and government institutions began linking.
Then my ISP started sending me large bills for increased bandwidth usage and I had to upgrade my package and as a consequence I literally had to find a way to make it pay or take it down.
Friends pointed out I made sensible recommendations for technical books on my site so why not join the "new" Amazon programme. This was in the days Jeff Bezos actually sent you a personalised welcome email.
That took care of my costs. I still earn good money from Amazon although since AdSense, it doesn't get as much real estate.
Then Google came along and things [traffic] sky rocketed for me and I built a dedicated site with my own domain name. Still have the old original site which from time to time I think about taking down but it continues to earn many, many times its annual costs.
Everything went along nicely and I was quite content, even started my own forum so I didn't have to answer a 100 questions a day.
Then came AdSense which I thought would be a flash in the pan. Heh! thanks to real time reporting I sat up real quick when I discovered in the first four hours I was earning more than weeks of Amazon income. Each day then exceeded more than a month of Amazon income.
Now the other big mistake newcomers make is writing useless content.
You seriously need to write sensibly, competently and fully about?
