SEO check of a website, with a report you can act on

Task. Show what a site check actually delivers. A training site for an invented roofing company has 6 pages with 14 SEO mistakes planted on purpose, and the check found exactly those 14 with no false alarms.

What gets checked: the sitemap and robots.txt, pages hidden from search, canonical addresses, page titles and descriptions (including duplicates), the H1 heading, image alt text, broken links and redirects, and how heavy the home page is on a phone.

The report comes in English or Russian, in three groups: what keeps pages out of search, what costs you impressions, and what is simply worth tidying. Each item says how to fix it and lists the pages where it was found. It covers only what can be checked, with no promises about rankings. A check of your site is 50 USD in one day, and after the fixes I run it again for free and send a before and after report.

Describe what you need in plain words. I will tell you what it takes and whether a smaller first version would serve you better. Scoping costs nothing.
