when zombie traffic starts, the keyword replacements seems to affect more keywords and short tails but the =>3 long tails keys seem to bee affected all time.
We Zombie traffic as:
-sudden start of "scrapping machines" like server***u.com
-visitors fetch one page and go back ( 100x bounce )
-start of legal search engines ( yandex, some chinese engines ) scanning the site
The zombie traffic starts with 10 min. with heavy zombie traffic and will slow down the day/next day. Following not converting traffic.
we are located in germany - CEST ( i think backdraft is in the same time zone but we do gave summer time now +1 hour )
