Transfer of layout to ISP Manager + configuration of Cloudflare, UTM redirects, and GA4

An experienced web developer is needed to deploy the finished HTML layout on the server (ISP Manager 6) and to fine-tune the environment. The domain works through Cloudflare. It is critically important to correctly set up traffic preservation from old links and conversion tracking.

Provided:

• Archive with the new layout (HTML/CSS/JS).
• Access to the ISP Manager 6 panel + SSH
• We will set up Cloudflare together
• List of short links for redirect configuration

Task list:

Deployment and basic setup:

• Upload the new layout to the hosting.
• Check the functionality of all internal links. (Add links from the old site where they are missing.)
• Important: There are no contact forms on the site. The "Subscribe" buttons lead to an external site. The mail server does not need to be configured.

Cloudflare and SSL setup:

• Issue an SSL certificate on the hosting (Let's Encrypt).
• Configure the encryption mode in Cloudflare SSL/TLS: Full.
• Set up a forced redirect of all traffic from HTTP to HTTPS.

Server settings (Nginx / .htaccess):

• Clean URL: Remove .html from page addresses (so that /page opens instead of /page.html).
• 404 handling: When trying to open a non-existent page, perform a 301 redirect to the Home page (do not show the standard 404 error page).

Source tracking system (UTM redirects):

• We have short links hosted online (like site.com/yt, site.com/inst, etc.).
• Need to set up server-side 301 redirects so that they lead to the home page with the addition of a UTM tag.
• Example: Request site.com/yt -> Redirect to site.com/?utm_source=youtube&utm_medium=social.
• I will provide the list of correspondences "short link -> utm tail".

Video optimization (Performance):

• Compress video files (currently they weigh 50-100 MB) into web formats (mp4/webm) without critical quality loss.
• Implement Lazy Loading: videos should not load when the page is opened. First, a lightweight preview image (poster) is shown, and the loading of the video file starts only when clicking Play.

Analytics and Cookies:

• Install the Google Analytics 4 code on all pages.
• Set up tracking of clicks on the "Buy" buttons as an Event.
• In the GA4 settings, mark this event as a Key Event (Key Event / Conversion) so that I can see conversions by traffic sources.
• Install the Cookie Consent script (popup notification about cookies), as we use analytics.

Requirements for the performer:

• Understanding of Nginx configuration (rewrite rules).
• Experience with ISP Manager and Cloudflare.
• Ability to work with events in GA4.
