Inaccurate SEO analysis

Hi,

I am writing this email to inform you about few problems I am facing using the SEO plugin Rank Math on the website https://www.sydneycontractingengineers.com.au/. This is my second attempt in contacting you guys as I have not received any information about this problem. Also, could you please give me a time frame to solve this issue.

The SEO Analysis feature of the plugin is completely inaccurate. Sometimes the result is 78% and after running the analysis again (without making any changes on the website) the result drops down to 51%. The result changes every time even if there are no changes made on the back end of the website. At this stage majority of the SEO options fail to work.

The plugin/analysis fails to detect basic SEO Analysis features like
1. Common keywords
2. SEO description
3. H2 headings
4. Keywords in title and description
5. Links ratio (fails to detect links – which is incorrect)
6. SEO title (failed to detect when results are under 60%)

The plugin/analysis fails to detect advanced SEO Analysis features like

1. Canonical Tag
2. Noindex Meta
3. OpenGraph Meta
4. Schema Meta Data
5. Image Headers Expire

I have already deleted cache multiple times and tried again but still I am getting conflicting results which is annoying.

For your reference I have photos if you want. Any help would be highly appreciated.
Cheers,
Pourus
