What risks can transfer guest access to Yandex webmaster/metrics/direct to a freelancer?

Question

Search Engine Optimization

In the process of searching for performers for certain work to promote the site, some of them are asked to provide them with guest access. It is clear that these accesses can help them to assess in what areas and how they have to work, to draw certain conclusions. But they ask them right from the doorstep, from their first message, even before the dialogue and cooperation began - and it’s not a fact that it will take place ...

In general, how can unscrupulous performers use the information received from guest access? For example, to sell statistics to competitors or just use someone else's statistics for themselves in some way useful to them?

Answer 1

Most likely, they will not be able to cause material harm to you.
If you are directly very suspicious, then:
1. They can use your achievements in their future work. This is if the account really has something interesting.
2. They can take screenshots from statistics and provide them as their cases. Again, if there is something to be proud of.
3. They can get hold of insider information. Large corporations are sometimes afraid of this, since the cost of a transition and the cost of a lead are directly tied to business indicators that are confidential.
If you are looking for a specialist, because advertising does not work anyway, and the business does not represent any special secrecy, then there is nothing to fear. It's just that everyone wants to criticize the current work in order to praise themselves and promise results.

Answer 2

You can remove the site from the search completely

Answer 3

If only to the metric ... then there is no particular risk.
