Developer to work on drupal site -- 3

https://cadconcrete.ca is the website.
Check the website and submit a proposal of what you are going to do for the price. From my experiences when there is not enough details customer or contractor expect more or less then the other party. So the more details the better.

Details would be something like these examples of services We need.

1. include 10 follow backlinks with a page score of minimum 30 page score according to google page rank score

2. Fix All mobile optimizations needed

3. Implement google tag manager

4. improve google lighthouse preformance ranks to 96 or better for all.

5. Any other thinks you can think of.

6. Write content for all pages for seo value. min 800 words per page

Drupal 9 run as a P.A.A.S. developed locally with lando. I am looking for an expert to Help improve website content quality, seo, mobile optimization.

my google lighthouse score for desktop is 94-performance 88-accessibility 93-best practices 92 seo
for mobile it is 65-88-87-90 most of the performance is due to image scaling and fluid containers I believe.
