The client communicates politely and responds quite quickly. There were no issues with payment.
However, if you plan to collaborate, make sure that the client fully understands all the nuances that you convey to them.
Before completing the task, I warned the client 4 times that the technical part on the platform can only be implemented at a basic level. I also informed them that I would document all the errors I find in the audit, and only those that the platform's functionality allows can be implemented. I warned them for the fourth time just before completing the task, writing directly: "But I will warn you once again, so there are no illusions or unpleasant surprises: some corrections will be impossible to implement due to the fact that the site is on a constructor platform."
Before this, I warned them three more times:
1) Technical optimization is possible on all sites except for the constructor platform. On the constructor platform, only basic technical work can be done.
2) The maximum that can be done for the constructor platform is to gather a semantic core, correctly write meta tags, create texts, do internal linking, and purchase backlinks.
3) In the audit, I understood that you want purely technical work. Therefore, from my side, I will document everything I find in the audit, and only what the platform allows can be implemented.
In the audit, I documented and detailed all important corrections for SEO. Which points are feasible and which are not should be reviewed by a programmer.
After completion, to my surprise, the client made comments regarding the presence of points that are impossible to implement (which they were warned about), and also asked why I did not immediately move these points to the lower part of the audit (which is not a problem and could have been done in 5 minutes, but this was not discussed before execution, although it was presented as a comment).
