There are many tools present for fixing and creating reports of your website's SEO optimization issues. It depends on you which tools you want to use, we can find paid and unpaid tools for SEO audit.
SEO Audit Tools like:-
Ahrefs
SEMrush
Ubbersuggest
These are very famous tools, but I want to suggest using screaming frog SEO spider tools, this tool deeply analyzed your website SEO optimization issue. SO you should use it.
Honestly, there’s no single “best” SEO audit software; it really depends on what you need.
If you’re more focused on technical audits and a full SEO Audit of the website, you can try KWT Spider.
This tool is really great, they provide you with a complete audit of your website, such as title, meta description, h1, h2, errors, broken pages, etc. Also, you can export your complete audit in CSV or Excel to share with the team or client.
