I am running an ecommerce site in Finland and we are ecperiencing a very strange traffic loss. Background to this is:
due to site maintenance our online store was down two days in April. Since that we have lost tons of traffic but what is most strange is that this traffic loss happens only in weekends. The traffic has dropped to 1/5-6 of what it was prior to site maintenance. The same applies when compared to the time year before. We have no idea what could cause this kind of non-logical traffic loss. We still have the same rankings in our important keywords so it can not be that and it wouldn't make sense if we lost the rankings for the weekends only.
Has anyone experienced this kind of problem before? Any ideas where to look or where to start with? Any help is appreciated since this is causing financial losses for us.
