Obviously, Penguin 2.1 seems to have recognized more recent link spam – those link spam that were created at a later time frame than the Penguin 2.0 rollout in May, Gabe said.
Of that link spam, Gabe said the following represent the culprits:
- Forum spam: This includes comments in forums with exact match anchor text links.
- Forum bio spam: Biographies of forum users containing exact match anchor text links.
- “Do follow” blogs: Blogs that don’t add nofollow to the links posted. “Let’s face it,” Gabe said. “Being listed on do-follow resource sites can absolutely send Google a signal that you are trying to game links.”
- Blogroll spam: Watch for blogroll links gone wrong. “Some may be fine,” Gabe said. “If you are unsure which ones are bad versus good, ask for help from a seasoned SEO.”
- Spammy directories: If you’ve used spammy directories in the past, and still have links out there, Gabe said “nuke them, have them nofollowed, or disavow them.”
- Blog comment signature spam: Google seems to be targeting these links even when they’re not followed, Gabe said.
Gabe also identified a new culprit: classified sites displaying up with large artificial, unnatural links resulting in location sites. He also said that, unfortunately, he has seen evidence of negative SEO rearing its ugly head during Penguin.2.1. raising its unpleasant head during Penguin 2.1.
I saw an entire business category (in a geo area) get hit with spammy links. That seemed very suspicious. All the business owners (who are competitors) were all blindsided.”
Tips and Recovery
- Understand that Penguin intensely objectives artificial unnatural links. Your new content and public action won’t induce a restoration.
- Thoroughly evaluate your link information, while keeping a eager eye on exact match and rich anchor text. That’s what Penguin objectives.
- Remove those links if you can, and disavow the remaining links. And use the domain operator in the disavow file when the domain is low-quality. Don’t try and target specific URLs on a spammy domain, when you can nuke the entire domain.
- Make sure more spam links are not being added as time goes on. business owners think they cleaned up their situation, only to get hit harder during Penguin 2.1. After checking their link profiles, you can clearly see more spammy links were added during the spring, summer, and fall. This is what got them hit by Penguin 2.1.
- Move fast and be aggressive. Penguin recoveries during Panda updates, so there is a possibility of recovery prior to the next official Penguin update.
