Today we want to present you with the current Top-100 of the most visible websites on Google.co.uk (This list, as well as the list of winners & losers, are updated weekly. To see all of them just click on SEO in the blue navigation bar in the SISTRIX Toolbox).
This post was originally published in Nov 2015. For August 2019 we’ve updated this list with the latest domains in google.co.uk mobile search to reflect Google’s mobile-first focus.
Domains market with XXXX are adult content only.
The Top-10 are dominated by US offers with only cambridge.org, the dictionary from Cambridge University Press, produced by a UK company. The Guardian and BBC sites feature strongly although if you add the two BBC sites together, they move into the top 10.
Wikipedia has by far the greatest visibility with 7,824.85 points (falling) , followed by YouTube with 3,047.80 points.
In terms of UK retail, and ignoring Amazon and Ebay, Argos leads. In health, the NHS has strengthened their position although the US-produced healthline.com is also gaining visibility. This will be an interesting one to watch, along with the US and UK based dictionaries at #9 and #10
At the moment, a website in the United Kingdom needs a Visibility Index score of around 60 points to enter into the Top-100.
How does SISTRIX calculate the Visibility Index?
We use a keyword set of 1.000.000 keywords (search phrases) and evaluate the first 100 search results on Google.co.uk to create a daily Visibility Index for Desktop and Mobile Search. The keywords are chosen in such a way that they reflect the average search behaviour for the UK.
The results are then weighed by position and search volume for each keyword. A ranking on the 10th spot for a keyword with a high searchvolume, such as “estate agent”, has a higher bearing on the calculations than a top position for a keyword such as “home purchase as investment opportunity“. We also incorporate the differing click-through-rates for different keywords. Finally, we accumulate all the values for all the rankings found for a domain, which results in the SISTRIX Visibility Index.
SISTRIX has been calculating the Visibility Index scores with great accuracy and reliability since 2008, and we now cover 30 countries.
