Major changes in the German Google Image Search

Major changes in Google's image search

Major changes in Google’s image search

The last weeks I observed many changes in Google’s image search. I usually focus on german image search but I also noticed some irritations on movements in the english / international image-search. Today I want to explain what happened in Germany – perhaps it may help to analyse other Google’s image-search versions. It’s allways like lost in the fog: are changes in the image search caused by changes to individual pages? Or has Google changed something fundamental to the algorithm? In Germany we have an “Image-Search Index“, called bidox. It oberserves the Top-100 positions of 5000 main keywords. Thanks to Ingo Henze for this free service. (What i describe in this article has nothing to do with the “porn-filter”!)

Here is what you can read out of the data. I combine domains of special types to groups.

Wikipedia lost a lot

Anyone who follows the Image Search updates has noticed that Google favors Wikipedia in the image search. Seems that at all relevant keywords at least one or two Wikipedia images are (or were) the front. Of course: correctly that are Wikimedia images. But the link from the Google image search leads to the corresponding Wikipedia page where the image is embedded.

Lost of Wikipedia-bidox

Wikipedia lost in the past week: from 1740 down to 1565, about 10% loss. This is the Bidox value – if you analize Wikipedia direct you can see the Wikipedia hasn’t “lost pictures”:  the number of images in the top 100 grow up by 895 images to 15,494 overall. This means that Wikipedia lost positions (for example, dropped from position 1 to position 4). Here the statistics:

Who could benefit?

First, the top-30 domains in Germany’s image search:

Bidox Top-30 (Dec 2013)

Bidox Top-30 (Dec 2013)

Most people won’t know how to interprete that. Therefore, the following is a differentiated evaluation.

The (german) Top Domains of Google Image Search

If Wikipedia has lost so many rankings, it remains much air for others. Who could benefit? I summarized some examples of domains into groups. First, the pos. 2 (blogspot.com) and pos. 4 (wordpress.com). Both are not really meaningful because that are thousand of individual blogs (the Bidox doesn’t differentiate from subdomains).

Bidox of blog-systems: Blogspot (#2) und WordPress (#4)

Bidox of blog-systems: Blogspot (#2) und WordPress (#4)

It shows that the pictures of this blog systems went down for two weeks, but now they are back. WordPress blogs seem to benefit a little bit more.

The following group is build by stockphoto-archives and photo-communities. (Btw: no Flickr, iStockphoto or Pixelio)

Bidox of stockphoto-services: 123rf (#3) - fotocommunity (#5) - deviantart (#19)

Bidox of stockphoto-services: 123rf (#3) – fotocommunity (#5) – deviantart (#19)

As you can see: the won a lot.

The next group is build by “fan-communities” (celebrities, gaming etc.):

Bidox of fan-communities: fanpop (#6) - wikia (#9) - posh24 (#14)

Bidox of fan-communities: fanpop (#6) – wikia (#9) – posh24 (#14)

All of the image-related comminities went up – often very much.

Next group are the main online-shops in germans image search.

Bidox of online-shops: otto (#7) - ebay (#18) - amazon (#36)

Bidox of online-shops: otto (#7) – ebay (#18) – amazon (#36)

Otto.de is in my eyes a special thing: they did a very good job. Ebey seems to be “Update resistent” – and Amazon lost images and positions.

Next group are automobile-communities:

Bidox of automobile-communities: motor-talk (#8) - autopixx (#22) - fahrzeugbilder (#41)

Bidox of automobile-communities: motor-talk (#8) – autopixx (#22) – fahrzeugbilder (#41)

Two of the went really strong up. User generated content in stable forums is a well strategy for Google image search – but of course they must be trustfull.

But not allways. And I must confess that annoys me a bit. I had reported about in my view very questionable business model (only in german). In this group I would still classify some more “galleries” of the Bidox-Top-100:

Bidox of ...-projects: vebidoo (#10) - animaatjes (#20) - academic.ru (#44)

Bidox of …-projects: vebidoo (#10) – animaatjes (#20) – academic.ru (#44)

The problem is: these sites monetize a lot of stolen images. They build systems that include automatically the top-images for many keywords – and the steal the link via hotlinking. It is an old well-known problem of Google-Images. Here my article about the method of academic.ru (german), just one of hundred examples.

Finally the main news-sites in Germany. To make it clearer i made two screens. The best neswpaper-Sites in Google’s image search Germany are:  Welt.de (Pos. #13) and Stern.de (Pos. #15).

Bidox of news-sites [1]: welt.de (#13) - stern.de (#15)

Bidox of news-sites [1]: welt.de (#13) – stern.de (#15)

The following are Süddeutsche.de (#23), Fokus.de (#24) and Spiegel.de (#50):

Bidox of news-sites [2]: Süddeutsche.de (#23) und Focus (#24)

Bidox of news-sites [2]: Süddeutsche.de (#23) und Focus (#24)

As you can see: all News-sites grow up extremely for two weeks, but in the last week the fall down again.

Conclusion: Causes of changes

The current changes in the Google image search seems to have two causes:

  1. First, about three weeks before the pictures of news sites were significantly preferred. The cause was probably an appreciation of the ranking factor “freshness“. This is consistent with my observations (and many others) – tons of very new images were shooted up into front positions. These images are supplied primarily by news sites (and partly by shops) – which usually have a very high crawl rate. In the past week the Freshness factor has been  turned back again. The news sites have all lost a significant number of images and positions.
  2. What is new is that Wikipedia images have obviously lost heavily positions. The first and second place of the Image Search are no longer reserved for Wikipdia.
  3. Many Bloggers told about changes in Google’s safeSearch Filter. This may caused something two – but I couldn’t see many changes because of this.

As a consequence I see many small Sites and Blogs as the winner of these Google algorithm changes. If it doesn’t work try out my article “Optimizing images for Google-imageSearch – image SEO basics“.

Who made observations in the english image-search? Is it possible that this is not only a change in german image search but also worldwide? Please tell me in the comments …
