4. How Google Panda Was Developed
• Google Engineer came up with questions.
• Sent questions to human quality testers who rated sites
– Rated based on quality, design, trustworthiness, speed, and
whether or not they would return to site
– Google came up with definition of “low quality”
• Launched Personal Chrome Site Blocker extension earlier.
– Allowed users to specify sites they want blocked from search
results
• Compared data from both sources (Raters and Chrome Blocker),
and had 84 percent overlap, indicating on right track
• Came up with Classifier to indicate Low Quality vs. High Quality
Sites, to be used mathematically in Google Panda.

7. Were You Hit by Panda?
•
•
•
•
•
Look at Web Analytics
Sites affected had traffic loss starting in February, 2011.
Google Analytics for your site (Web Trends, Omniture, etc.)
SEM Rush for most sites (SEMRush.com)
How many sites recover?

on site via your web analytics

Quality Guidelines”.

dates of Google Updates.

13. Recovering from Penguin
• Perform a full SEO Audit of web site
– Identify and fix problem areas on site that violate Google
guidelines (keyword stuffing, over optimization, etc.)
• Review Google Webmaster Tools for messages, suggestions
• Perform full link analysis of site
– Download links from Majestic SEO, Moz Open Site Explorer,
a hrefs, etc.
– Review anchor text, clean up links to site
– LinkResearchTools.com for further cleanup

14. Exact Match Domain Update
• Exact-Match Domain (EMD) Update — September 27, 2012
Should be called the “Commercial Phrase” Update. But for PR purposes, I realize
why Google calls it the “EMD” update.
• Google targeted “commercial phrases” with this update.
• AdWords CPC Cost + # Searches Per Month = Commercial Phrase
• Example:
–
•
•
•
•
$5.00 CPC + 20,000 Searches Per Month = Commercial Phrase
Valuable Domain Names include Keywords (commercial phrases)
Not all keyword rich domains affected
Sites without keyword rich domains were affected
Recover by cleaning up your link profile, especially anchor text
• Link Profiles should have 70 percent or more “brand”
anchor text, company name, URL as anchor text.

15. Page Layout Update
•
•
•
•
Page Layout #2 — October 9, 2012
Google targeted pages with too many ads “above the fold”
http://browsersize.googlelabs.com/
Algo proof: content above fold, minimal ads above the fold.

•
•

•
•
•
•
•
Have an unnatural link warning in Google Webmaster Tools?
Sample Unnatural Link Warning shown below
Process for Recovering from Unnatural Link Warnings:
Clean Up Links, Disavow, Reinclusion Request

18. Cleaning Up Your Links
•
•
•
•
•
•
Review all your links (Majestic SEO, a hrefs, Webmaster Tools)
LinkResearchTools .com Link Detox Tool
Identify Toxic and Suspicious Links. Review by hand!
Notify site owners of toxic links, review suspicious links
Be nice, ask, beg for removals. No C&D from your lawyer!
If no answer, prepare Link Disavow list

19. Link Removal Requests
•
•
•
•
•
•
Get organized. MS Excel, Google Docs spreadsheet
Include URL, Status, Date Contacted, Anchor Text, Notes
Find domain owner (whois data, contact info on site)
Ask for link removal or anchor text change if appropriate
Realize that some links won’t be removed (thus disavow tool)
Remember: Disavow is not required in order to recover.

20. Google Disavow Tool
•
•
•
•
What is Disavow? (Bing has Disavow tool, too)
Disavow is an advanced tool – use with caution
Not all sites should disavow links
Should You Disavow Links? How to Know
- check your backlink profile, look for toxic links
- if you have a rogue former SEO firm who built bad links
- if you have negative SEO done to your site
• Disavow should be a “last resort” effort. It’s not a magic bullet
for ranking better.
• Carry on with your ‘normal’ linking, link earning activities (or
do more of it)

21. Google Hummingbird
•
•
•
•
Did you notice when Hummingbird went live? I didn’t.
Some say Hummingbird was a publicity stunt by Google.
Hummingbird is the “back end” or “engine” of organic SERPs.
Google’s blog post doesn’t mention Hummingbird, but mentions
Knowledge Graph

23. Your Content Strategy
• Content Marketing, on your own site, is key
• Review Google’s 23 Questions to Assess Quality
•
http://googlewebmastercentral.blogspot.com/2011/05/more-guidance-on-building-highquality.html
Examples:
• Would you trust the info presented in this article?
• Is this article written by an expert or enthusiast who
knows the topic well, or is it more shallow in nature?
• Does the site have duplicate, overlapping, or
redundant articles on the same or similar topics with
slightly different keyword variations?

24. Combine Social Media with SEO
•
•
•
•
Create content on site, promote on social sites
Twitter links, mentions of URL are seen as links.
Post on Google+, +1 the URL, add to Facebook page
Encourage social sharing of your site’s content

25. Social Validation
New URLs need Social Validation
•
•
•
•
•
•
Google looks for new URLs they can trust
Google “trusts” new URLs if social shares (validation)
New content must be socialized within 2 hours
After 2 hours, new URLs are not “fresh”
Submit new URLs (blog posts, articles, even new sites/domains
Share on Facebook Page, Google+, Twitter,
LinkedIn, other social sites
