Fast initial response
Speed up the homepage — most users arrive on a phone, and a slow first load loses them before the page shows.
Fast revenue-leak triage
portzero.net is 2 fixes away from more trial signups.
The public site has a solid foundation. The remaining money is likely in sharper positioning, AI-readable entity signals, and conversion-path testing.

How The Page Sells
8 of 8 of the buying-decision signals we could verify are on your site today. The page already shows 8 of 8 buying-decision elements. The remaining lift is in sharpening the ones that are missing, not rebuilding the page.
Below is the breakdown: what's already working (with the exact text quoted from your page as proof), and the highest-impact additions to win more trial signups — in priority order.
Scope: an automated scan of the 5 pages we could read across your site. Every “found” item quotes the exact text on your page so you can verify it. It doesn't judge copy quality or design.
Selling well (detected, with proof)
- Clear value proposition (headline) — found: “Eliminate port conflicts”
- Action-oriented primary CTA — found: “Get started”
- Social proof (testimonial / customers / rating) — found: “review”
- Specific, quantified result — found: “1. K” (on /terms)
- Risk reversal (trial / guarantee / no card) — found: “Free forever”
- Visible pricing / 'starting at' anchor — found: “Pricing”
- Easy lead-capture path — found: “Contact us”
- Objection handling (FAQ) — found: “FAQ” (on /docs/how-it-works)
Highest-impact additions to sell more
- All readable selling elements were detected. Test and sharpen the existing copy.

- Compress and lazy-load images; serve modern formats (WebP/AVIF).
- Put the site behind a CDN and enable caching of static assets.
- Defer non-critical JavaScript so the first screen paints fast.
2. Sitemap present
Publish /sitemap.xml and submit it to search engines.
- Publish /sitemap.xml listing every indexable URL with <lastmod>.
- Reference it from robots.txt and submit it in Google Search Console.
- Regenerate it automatically whenever pages change.

Why it matters
The fastest users do not read every page. They scan the first screen, trust signals, pricing cues and how easy it is to start a free trial. Missing signals make the offer harder to understand and easier to ignore.
