Arend Group · How we measure
What we measure,
and what we honestly don't
Our measurement in short
We start from a brand's actual product catalogue and look up each item by its EAN code at every retailer.
We only read public pages, as a visitor sees them, and we follow the rules a website sets for itself.
Every figure shows how much we were actually able to measure. Not measured is not the same as not found.
What we measure
Online presence
Is an item online at this retailer, and with what information?
Per item and per retailer.
Readability for search engines and AI
Can a search engine or AI assistant read the product page properly?
Product data, sitemap, access for bots.
Local reach
How many retailers around an address have the item online?
Says nothing about the stock in the shop itself.
Mentions in AI answers
How often does an AI assistant name a brand in a product category?
Indicative, with a margin of error.
What we don't measure
Positions in Google, Google AI Overviews and answers from services without open access.
We show these as not measured.
Why this matters
You see per item where things go wrong, not just an average.
Every figure shows its coverage, so you know how far you can rely on it.
Measurement errors are corrected and the measurement learns from them.
No workarounds: we don't pose as an ordinary visitor and we don't bypass blocks.
How a measurement works
1
The brand's catalogue is loaded, with EAN codes.
2
Our measuring bot calmly visits the retailers' public pages.
3
Results are checked and grouped per item and retailer.
4
After improvements we measure again, so the effect becomes visible.
Good to know
Our measuring bot identifies itself with its own name and an explanation page.
We respect a website that doesn't want bots. That retailer is then listed as not measured.
AI answers vary from day to day. We don't count small shifts as movement.
We make no predictions about sales or revenue.
Frequently asked questions
Are you a retailer and don't want to be measured?
Let us know, or exclude our bot through your robots.txt.
How often do you measure?
Continuously and evenly spread, so that no website is put under strain.
Why not just use a well-known SEO tool?
Those don't know your product catalogue or your retailers. We start from every item.
Can I look at the method?
Yes, customers get an explanation for each figure.
