The whole purpose of mayday was to eliminate websites who don't do on page optimization, adding more pages, refresh content.
That wasn't exactly my understanding. Here's what Google's Maile Ohye said:
Mayday was a significant update that really impacted long tail terms. A lot of people were leveraging long tail phrases for lots of traffic but it was frequently done via automated methods. We’ve looked to eliminate spam, and that’s been a big priority for us. At the same time, there were people developing not quality content (not a violation of guidelines, but also not providing value). What it does is for long tail queries, is we now just consider them queries like anything else. We are going to put as much value in those search results as all search results.
Now the actual effect may have been different from this is some sectors, but this was the intention.
