Welcome to the Q&A Forum

We are conducting a large-scale Penguin cleanup / link cleaning exercise across 50+ properties that have been on the market mostly all for 10+ years. There is a lot of link data to sift through and we are wondering how we should prioritize the effort.

So far we have been collecting backlink data for all properties from AHref, GWT, SeoMajestic and OSE and consolidated the data using home-grown tools.

As a next step we are obviously going through the link cleaning process. We are interested in getting feedback on how we are planning to prioritize the link removal work. Put in other words we want to vet if the community agrees with what we consider are the most harmful type of links for penguin.

• Priority 1: Clean up site-wide links with money-words; if possible keep a single-page link
• Priority 2: Clean up or rename all money keyword links for money keywords in the top 10 anchor link name distribution
• Priority 3: Clean up no-brand sitewide links; if possible keep a single-page link
• Priority 4: Clean up low-quality links (other niche or no link juice)
• Priority 5: Clean up multiple links from same IP C class

Does this sound like a sound approach? Would you prioritize this list differently?

Thank you for any feedback /T

Atul,

What I mean by it is that all domains hosted under the same server IP (=dedicated root server) have experienced significant ranking drops that seem tied to a global penalty.

However it is questionable if Google would be considering this a valid approach given the probability that other domains could be hosted under the same IP that are not associated with the to-be-penalized URL.
