Tuesday I reported that Google said nothing changed with when you should use the disavow file when it comes to Penguin - well, that might not be true now.
Demotes would mean that it would lower the rankings of a web site for doing something bad. Devalues means it would likely ignore the link spam and not downgrade the rank of the web site. It might feel like a demotion when a link is not counted. Instead of dropping down let's say 10 pages, you might only drop a page because those links no longer have any value but there is no additional demotion to your web site.
So those who may be recovering now, because Google is rolling out Penguin 3.0 recoveries now - might not feel a full recovery - if that makes sense.
That means a bunch of things but in terms of the disavow file - you likely do not need to use it anymore specifically for Penguin. Since devaluing the link is like ignoring the link, disavowing the link is the same thing.
Of course, you still need it for other link penalties, like the manual actions but doesn't seem you need it for Penguin.
Gary Illyes from Google told me this on this Facebook post:
Traditionally, webspam algorithms demoted whole sites. With this one we managed to devalue spam instead of demoting AND it's also more granular AND it's realtime. Once the rollout is complete, I strongly believe many people will be happier, and that makes me happy
I asked him to explain devalue vs demote for Penguin and he added:
Demote as in adjust the rank of a site.
Devalue as in "oh look, some crap coming towards this site. Let's make sure it won't affect its ranking"
I then said, so we don't need the disavow for Penguin and he said:
For penguin specifically there's less need, yes, but if you see the crap, you can help us help you by using it. Also, manual actions are still there, so if we see that someone is systematically trying to spam, the manual actions team might take a harsher action against the site.
This is a huge change:
(1) Penguin 4 devalues granularly on a page by page basis (known)
(2) It devalues doesn't demote
(3) It doesn't require use of the disavow file because it only devalues those links
(4) Webmasters should be happier with it because of this
Ana Hoffman also summed it up in my Facebook post comments and Gary said it looks right to him. She wrote:
If a site has spammy links pointed to it;
- it won't be penalized for those links like Penguin would've done in the past (algorithmically)
- the spammy links will be devalued
- thus the site certainly won't benefit from those spammy links
- but could potentially go down in rankings had those links helped the site to gain higher rankings to begin with.
