How to Use Keyword Groups to Help your Keyword Research

The SISTRIX Toolbox will classify and sort all keywords for a domain into useful groups, in order to give you a quick and easy overview of the topics covered in a website. Use this feature to identify strong keyword groups that your competitors are ranking for, to analyse your main keyword focus and identify the relevant topics for your keyword research.

The Keyword Groups in the SISTRIX Toolbox

Do you know what keywords you are ranking for? The keyword groups feature can quickly expose ranking keywords that you might not realise that the domain ranks for.

You’ll find the feature Keyword Groups in the SEO module of the SISTRIX Toolbox.

After typing the domain (or subdomain, directory or URL) you’re interested in in the search bar 1 , the feature will appear in the menu on the left of the screen, inside the category “Keywords” 2.

The two buttons on the top right corner of the screen will allow you to export the page as a PDF (using some credits) or share it on Social Media ().

The Keyword Groups evaluation in the Toolbox will look at the entire ranking keyword set for the domain and group them into usefull clusters according to their similarity.

The table of the Keyword Groups offers the following options:

3 Keyword group: the terms which have been found in the domain’s keywords ordered according to their frequency.

4 Number of keywords: the total amount of keywords that contain that term.

5 Show keywords: click on this entry to see all the keywords that have been grouped under a specific term.

6 Help / option buttons: the question mark allows you to gain more information about the table data, while the option button will let you add the table to a Dashboard and a Report, or export it as a CSV file.

As we can see from the table, it’s easy to gain an overview of the main topics covered by the website, which can be analysed in more detail by clicking on the “show keywords” entry.

The Keyword Groups are created automatically by the Toolbox so you may not find every single useful term for your keyword research. Feel free to download the table to sort and analyse in a spreadsheet or database.

Expose the content strategy of a direct competitor

If you find a domain competitor (tutorial: competitor analysis) that has a much higher Visibility Index, it could could be that they are doing a better SEO job. However, it could also be that they rank for a wider range of topics because of a different content strategy. You can easily spot this using keyword groups.

Two examples below show the domains of two businesses that have similar business models. They sell used cars and the home pages include a search tool and some special offers.

The two domains have extremely different levels of Visibility (mobile Visibility, main website shown). Before assuming that one is ‘better’ than the other, we need to see if the content models of the two sites are the same. By looking at keyword groups we can do that easily.

Keyword groups – www.autotrader.co.uk
Keyword groups – www.arnoldclark.com

A quick comparison shows a group called ‘review’ that appears on autotrader.co.uk but not on arnoldclark.com. There’s also a motorcycle and caravan group that’s ranking. This is a good starting point for further analysis.

Don’t forget that sub-domains under the main domain can often contain different content. Be aware of this when analysing domains. If a website appears under, for example, www.[domainname] then analyse the keyword groups in that for a better overview of the main site content.

Spot hacked Websites

This feature is also very useful to spot websites that have been hacked or infected, as the table will show keywords unrelated to the domain’s content.

This is the case with the domain above, a hotel in Kent which ranked for keywords related to clothes and shoes after the site was hacked.

If we click on the term “Dress” the Toolbox shows us all the related keywords for which the domain is ranking. A look at the ranking URLs is enough to confirm that the website has been hacked.
