Meta description NSS

A domain's Meta description NSS (normalised similarity score) provides a numerical value for how similar in meaning its meta description is to the meta description of the principal domain.

NOTE It is not always possible to obtain metadata for a domain, so this score is not always available for every domain in a report.

Calculating Meta description NSS

We use OpenAI to compare meta description texts, and report the similarity as a normalised score between 0 and 1. For example, consider this meta description:

We are the Partnership Bank. We provide simple, flexible, financial services to UK customers directly and through partnerships with well-known UK brands.

Here are some sample comparison scores:

Meta description Meta description NSS
We are the largest UK retail and commercial financial services provider, with 26 million customers and a leading digital presence. 0.9457
At Bank of Kneebonia, whether you're looking for a business bank account, business loan, asset finance or something else, we're here to help business customers. 0.938
A globally connected network powered by businesses across Northern Elbonia. Discover what NE Chamber can do to help your business grow. 0.8921
The most user-friendly app for events. Organize an event in a moment and engage the audience using networking, social wall, notifications... 0.8659

In practice, almost all Meta description NSS scores are between 0.7 and 1, or zero (zero scores occur when it has not been possible to obtain metadata for a domain). Only scores of 0.9 or above should be regarded as 'significant' when considering this metric.

Visualising Meta description NSS

In the main visualisation of a report interactive, the 'Meta description NSS' view re-colours the domains to indicate if their scores are significant or not.

Viewing Meta description NSS values

All worksheets in the MS Excel file for a report that list domains contain a Meta description NSS column for this attribute.
