Try to find the platform where the functionality is high. Will be perfect if this platform can show the situation with rankings and give full information about site audit. I know a few, if you need I can share in PM.

also try rankactive.com , their site auditor is very well, also you can check rankings, do optimization and lots of other actions, you can find all the info on their site

For my personal opinion i'm using Website auditor from this website https://www.link-assistant.com/website-auditor/

Search for 'white label seo audit tool' in Google and you can see plenty of such tools

I am using IBP reporter and it's been working well for last few year with satisfaction. This also gives competitors report. You will have it here http://www.ibusinesspromoter.com/
