Much has been written about messages in GWT to help sites that have strayed outside Google's Guidelines. I'm guessing the sites receiving these messages range from those tripping over a spam threshold due to ignorance of the "rules" through to full on black hat spamming. Whatever the case, these sites get some guidance on the issues to be fixed.
But there is another mostly ignored category of sites, also clobbered on Penguin dates, that have never received any message. Apparently, this group have to work it all out for themselves.
All the Penguin related advice/information/guidance/videos that I have seen seem to be saying that if you have a site that does NOT receive a GWT message, then the site has been affected by ongoing automated algo changes, not a manual action such as Penguin.
My understanding is that in cases such as this:
a) Remedial action needs to address whatever tripped the algo (good luck figuring that out!)
b) Any successful changes should have an effect as soon as the pages have been re-spidered and indexed. ie.. there is no wait period until the next Penguin run.
c) Reconsideration requests are not required (because the site has not actually been penalised) and will be ignored.
d) If bad inbound links are suspected as a problem, a disavowal request CAN be submitted. This is not limited to just Penguin affected sites.
Is this the correct interpretation for sites that seem to have been hit by Penguin but which have no GWT messages?
