Audit of a fishing and tourism goods store

Based on the results of the audit, the following comments were made:
• Robots.txt contains a link to a sitemap with an insecure http protocol.
• Links to products from pagination pages were made with the pagination parameter. We got rid of duplicates by banning the indexing of pagination pages. As a result, all pagination pages were closed from the index, which is wrong. It is recommended to correct links to product pages and open pagination pages for indexing.
• A copy of the main page of the site was detected at the technical address. The duplicate turned out to be allowed for indexing.
• 2 Sitemaps. For Yandex and for all other bots. The last one didn't work.
• The working sitemap content is out of date and included confusion between sitemap versions.
• 2300 product pages without titles.
• 60 pages with duplicate titles.
• Almost 200 pages with short titles.
• Almost 700 pages without description.
• Page 97 without H1.
• 3900 pages - false H1.
• 4200 pages more than one H1.
• 5000 images without alternative text.
• Micromarking for linking in search is completely absent.
• Micro-markup for creating links on social networks without pictures and with unsightly text.
• The design of sections on the main page looks like an unfinished website template.
• Large text at the beginning of section pages pushed the product far down.
• The “Buy” button did not have the greatest visual weight.
• Store pages do not fully support the mobile version.
