On all those counts above this particular site does very well its been stable for many years. 100% unique content, 1000 pages, 7 years, good organic traffic and no reason to be hit by any google update. 12 months would take it into 6 figures which might seem a lot but it’s a great earner.
Thanks for letting me know about ukbingosites.co.uk, it’s on now, not sure why you were getting a 404 earlier
