About the 'life cycle' -- it's valid for many of the websites (and even services offline), but I'll point to some facts: some websites exist only a year (or even less), because their owners can't earn even enough to pay the domain and hosting. I know different cases like: "I've got a great idea! I'll be rich!... Oh... it's not working so well. OMG, I didn't earn even these 30 (25, 50, whatever) dollars back!!! Hell, I can't afford to pay it for another year. Who wants, it for free?"... These are many cases, every year. Maybe all of us noticed how many new sites are coming up and then disappearing forever.
Other exceptions: 'Rigid' websites. They just exist like monuments. The owners are not willing to abandon them and they continue to pay every year domain and hosting. Most of the content is the same, unchangeable. No development, no cycle. I have a perfect example -- a forum ('The First Bulgarian Virtual Pub') I sold out years ago (for USD100): kry4ma.com (

About that webmasters' discussion, I haven't this kind of observation. Forums that ranked well before (I remember them) are ranking still well now. (I checked some of the keywords and the 'long-tails' around an hour ago.)
An example of a forum that's doing well long time already and having a comparatively small predominant language (Bulgarian) is a forum about parenting, babies, kids, etc. -- bg-mamma.com (
http://www.alexa.com/siteinfo/bg-mamma.com). According to this
https://www.similarweb.com/website/bg-mamma.com#overview it gets around 3.8 million visitors monthly.
By the way, I don't remember if it was mentioned already, so I'll say about it:
http://www.thebiggestboards.com/largest.php (a list of very big forums, by post count).
I'm not an oracle (in fact, I think they do not exist
), so I can't be sure, if Google 'likes' less the forums, but what I can see and feel is that a well-written content (with other SEO support as:
- shared/linked in other sites
- visited by many netizens)
is going to rank high, no matter on what platform it's based (blog, forum, wiki, etc.) But it matters, of course how aged and how trusted is this concrete platform. Guess which is better -- an old website (aged) with good
link juice or a new one without any
link building?
