Link Juice Hack for PDF Files

PDF documents are abundant on the web. A quick search will return over one billion results from Google’s index and almost all of these documents will have outbound links. Surprisingly all evidence so far suggests that by design, PDF documents don’t circulate link signals the way HTML documents do.

 

Google Reclassifies Certain Types of Thin Content Pages

Topics: Content Marketing, Experiments, SERPs

Post Penguin Update

We have new data which shows that the 25th October spike wasn’t part of the gradual Penguin 3 roll-out. It appears the update had a lot to do with on-page factors and is (among other things) related to how Google treats thin content pages and soft 404s.…

 

Link Memory: SEO Experiment Result

Link Memory

In April 2014 an experiment designed to test the influence of anchor text on URL rewriting showed positive results. Google chose inbound link anchor text value to override uninformative page title in SERPs. After the first stage of the experiment had concluded we removed all inbound links to the test page.…

 

Co-Occurrence as a Ranking Signal

TL;DR: A little-known property of Google Books search highlights co-occurrence as a ranking signal.

The concept of co-occurrence (not to be confused with co-citation) has been on the radar of many search professionals for a while. I accepted the idea as common sense and never thought to investigate it further, then one day I stumbled into a peculiar set of search results which lead to what appears to be conclusive evidence of Google’s use of co-occurrence in their search results.…

googleception

Jim Munro spotted an interesting anomaly in Google’s search results the other day, a case of Google indexing its own search results. This is not something you see every day. I went to investigate and noticed that all Google’s URLs returned in this search query had one thing in common – //.…

 

Experiment Results: Influence of Anchor Text on Document Title Rewriting

Can anchor text influence uninformative title tag replacement?

In 2012 we examined Google’s document title rewriting behaviour in order to create a list of contributing factors.

Why Red Bull Has Two Verified Google+ Pages

Google+ wants real identities for both humans and organisations. There can be only one!

That said, look what happens when you search for “Red Bull” in Google Plus:

Red Bull Search

We’re seeing two official Red Bull pages, both verified. So which one is real?…

 

Separating Local and Organic Traffic in Google Webmaster Tools

Today I’m going to share a dead-simple Google Webmaster Tools hack that will help you split up pure organic impressions and clicks from Google’s local results. Hack is maybe a strong word, in any case it’s a workaround which compensates for the missing “Google Places” filter.…

 

Reddit: Google’s Semantic Data-Mining Opportunity

Look at this perfectly looped image sequence. It’s link building, chain making, Futurama, factory… it’s satisfying, and hypnotic. Google, however, won’t be able to link these concepts well enough unless it’s fed structured semantic data. They must find creative ways to correlate “strings” and understand “things” as webmasters don’t always have a habit of structuring their data, just like they don’t always use rel=”nofollow” or write clean code.…

 

The Art of Link Earning

Exactly two years ago, I published a little study on link anatomy [PDF] from link builder’s point of view and many were surprised to see so many attributes attached to something so simple as a link. Today will focus on the left hemisphere of the diagram with attention to organic acquisition scenarios (excluding any direct manipulation in the link earning process).…
