IndexWatch 2015 – The Losers 2015 in UK: 100 domains with the highest loss in Google visibility

2. February 2016, 11:34

Two weeks ago we showed you the domains which managed to gain the most Visibility during 2015 on As promised, today we will look at those who were not so fortunate between January 5, 2015 and January 4, 2016 on For this list, we once again looked at all domains which had at least 5 points of Visibility at the start of 2015.

We start with a short example of how a loss of Visibility can impact a website’s bottom line. In 2014 it was reported that, after the launch of their new website, the online sales of Marks & Spencer fell by 8.1 percent in the 13 weeks leading up to June 28. They lost 11 points Visibility (-19%):

Today, only 100 domains in the UK have a Visibility of at least 62,25 points, while most domains have a Visibility of less than one point. So when a domain loses more than 100 points, like did – which we will look at shortly – we can agree that something big must have gone wrong. Read Full Article

IndexWatch 2015 – The Winners 2015 in UK: 100 domains with the highest increase in Google visibility

20. January 2016, 09:03

Our yearly IndexWatch 2015 for the United Kingdom is ready. For this list we use our SISTRIX Visibility Index score, which shows how visible a domain is in the Google search result pages for the specific country-index.

For our IndexWatch 2015 winners, we looked at all visibility increases from January 5th, 2015, until January 4th, 2016. We considered at all domains with at least 5 points on the Visibility Index at the start of 2015. Our list is a great tool to quickly assess how a domain has fared during 2015 on Google and shows the hard work the website operators and SEOs put into their domains in the past 12 month.

Introducing Our Amazon Keyword Tool

14. January 2016, 11:22

Let’s start out with an uncomfortable truth: e-commerce searches are not one of Google’s strong points. It also does not seem that Google has any usable approach to attack this problem in the future. Looking at a recent survey by BloomReach among 2.000 US-American consumers, Amazon is the largest shopping-searchengine: 44% of all product-searches start on Amazon. Only 34% happen on the classic Searchengines like Google, Bing or Yahoo. A direct search on the vendors pages is only made by 21% of those surveyed. If we keep in mind that Amazon has above-average success in the quickly growing area of smartphone shopping, it becomes quite evident that we should take a look at Amazon’s product search.

The search behavior on Amazon is naturally very different than on Google: it starts with the user usually having a concrete buying intend, passes through a different SERP-layout but ultimately ends, time and time again, at the keyword itself. We wanted to make this part of the platform more transparent, so we created a keyword-database for Amazon. For this Amazon Keyword Tool we collected several million typical searchqueries on the Amazon-search. An exemplary result looks like this:


Once you type a query into the search bar, we will search through our keyword database in the fraction of a second for the appropriate keywords.

The first three bar graphs will show you the distribution of the keywords for the hits, the average price and the average rating.

On top of the results table we will show you an evaluation of keyword-components which show up extremely often within the first 10.000 results. Thanks to these, you will get a good idea of the relevant brands and terms containing to the subject matter.

Afterwards you will find the actual keyword-table. The first row shows the keyword itself. If the keyword uses a brand name which is frequently sold on Amazon we will show this with a (Brand) in Grey behind the keyword. Next you will see a bar which will give you an idea of the amount of hits Amazon returns for the search query. Followed by the average price for the 16 results on the first resultspage for the keyword. Thanks to this value, you can quickly get an idea if the result is for a high-priced item or just a low-priced accessory. The last row will show you a bar with the average amount of ratings for the first 16 results. Here you will notice if lots of buyers are engaging with the product.

While Christmas is already over, we still have a present for you: we are giving away this data. You can research up to 25 keywords a day absolutely free and anonymously. If you do have some kind of SISTRIX-account (current customer, previous customer, testaccount, anything – as long as it has a login) you can research up to 250 keywords a day. You will find the Keyword-Tool on We hope you will have a lot of fun with our new feature and we wish you a great start into the year. It will surely be interesting.

Google Penguin – How are the victims from 2012 doing today?

17. December 2015, 13:58

We will most likely see the Google Penguin 4.0 update early next year. This makes it a great time to look back at the domains on that were penalized by the very first Google Penguin update in 2012 and see how they are doing today?

I decided to select the first 100 domains with a significant visibility drop during the initial Penguin rollout as the basis for my evaluation, as they are the most likely to have been affected by this link penalty filter. Looking at this “selected“ group (google sheet), here are my conclusions: Read Full Article

The New Website For The Mayor Of London Neglected Its /priorities/

8. December 2015, 14:54

The Mayor of London Boris Johnson announced that the website for the Mayor of London has been redesigned to be closer to Londoners. A true statement, as the new design is a positive change, though they lost about 40% of their visibility on Google in the process. This means that now, they are even less visible than in 2011. This problem must be solved, otherwise their visibility on Google will continue to decrease.

Why Thanksgiving fluctuations may not necessarily have to be Google Updates

29. November 2015, 08:47

All over the past week there has been major movement in the Google SERPs and many SEOs believe that the source of all the commotion is a Google Update. Google’s John Mueller, however, said on Twitter that these may just be regular changes to their Algorithms and not a Google Update.

My goal for this post is to give you an explanation of why such ranking changes do not have to be Google Updates. These ranking changes can be observed, measured and, if you understand them well, you can gain great benefits from them. Let me start at a fundamental principle and give you some precise examples.

UK Top 100 Domains – The most visible Websites on

17. November 2015, 14:37

SISTRIX has been analyzing the visibility of practically all domains with rankings on, since 2010. This SISTRIX Visibility Index score is well suited to easily compare domains with each other. It is also ideal if you want to measure and evaluate the success of SEO actions taken or if you want to analyse the impact of Google’s algorithm changes on a domain. The Visibility Index can also be broken down to evaluate subdomains, directories and individual URLs on the domain.

The Visibility Index allows for compelling competitive analysis of your competitors. You can identify the most successful websites for a certain segment, discover the reasons for their success and use this knowledge as a “best practice example” to increase the success of your own project. Thus, it is easy to recognize and adapt SEO-methods which have been successful and are ideal to follow.

The Visibility Index score for has crashed and there are no signs that the domain name has changed or that a redesign took place.

On the Visibility Index chart for you can see that SISTRIX automatically adds pins noting known Google updates, if the domain’s visibility has significantly changed within the week of the update. Apparently, reacted sensitively to Google Panda, though right before the domain’s visibility crashed, there are no signs indicating a Google penalty.

It therefore begs the question if has been hit by a Manual Action by Google. Could it have been a manual Link Penalty? Let’s check the facts.

The Price of Changing the Domain Name

5. November 2015, 15:11

In theory, changing your domain name should not be complicated, especially if you follow the instructions Google provides. In practice, we can find numerous examples that contradict such rosy expectations. Changing the address of a website will always be accompanied by a certain degree of risk and the price you pay, in the end, could be higher than your initial estimates, with the currency usually being the search engine rankings you worked so hard for.

The most popular example is, where it took two long years before they managed to get back to the same level of visibility within Google that they had before the domain name change. This is also a great example for how Google can take a long time, three month in this case, before the entire domain was crawled and processed.

What are the consequences that a domain change can cause and what might be the reasons for a drop in visibility afterwards? In this blog post we will use a more recent example to show you what may happen after a domain name change. Read Full Article

Click probabilities in the Google SERPs

27. October 2015, 16:41

Ever since there has been such as thing as search engine optimization, the question of “How often are people clicking on each ranking position?” has been posed. Of course, there is no universal answer to this question – too many factors have a bearing on the click probability per position: the intention or the time of the search, the device used and many more. Despite this, people are regularly trying to give an answer and today, I would like to add another attempt. The charts are part of my lecture at this year’s SEODay in Cologne, Germany.

The following numbers are based on the new Google Search Console API. This allows data from the Search Console to be collected and processed automatically. We were the first tool provider to integrate this feature in our software, shortly after its release. Some of our customers have granted me permission to use their data for an anonymous and summarized evaluation – for which I would like to say thank you. Through this, 124,086,615 clicks from one week in September were accumulated.
