Anything we couldn’t read is its own segment — a page that blocks our reader is our limitation, not a mark against you, and it never lowers your score.

Priorities

Fix these first

Ranked by revenue impact. Each one is something developers — or an AI answer engine — need to see and currently can't. Fixing the top few moves your score the most.

01

No obvious button to start

Add a prominent call-to-action that encourages users to start coding immediately.

02

Search engines can’t tell what you sell

Add structured data (LocalBusiness / Organization schema: address, hours, phone, ratings) so search engines show you with rich results.

03

No price anywhere on the page

Include clear pricing information or a free trial offer to entice users to sign up.

04

No easy way to get in touch

Simplify the process for users to get support or feedback on their coding experience.

05

AI assistants have nothing to read

Publish /llms.txt with a concise machine-readable product summary, audience, pricing, and docs links.

06

Search engines have no map of your site

Publish /sitemap.xml and submit it to search engines.

What we read on your page

What a customer finds — and doesn’t

1 of the 8 things we could check are already on your page. We found only 1 of the 8 things a customer looks for before they act. Most visitors are leaving without enough reason to call, book or buy.

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 1 page 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.

Already on your page

  • A headline that says what you do — found: “Welcome to BrowserCode”

What to add, in order of impact

  • An obvious button that starts the thing — Your visible link text is passive (found: "Learn more"). Replace it with an action CTA like "Start free" or "Book a demo".
  • Reviews or proof from real customers — Add a testimonial, customer logo, star rating, or an 'N customers' proof point near the top.
  • A concrete number, not an adjective — Add a concrete number (result %, time saved, customers served). Specifics convert better than adjectives.
  • Something that removes the risk of trying you — Lower perceived risk: free trial, money-back guarantee, no credit card, or cancel-anytime.
  • A price, or at least a from-figure — Show pricing or a 'starting at' anchor so buyers can self-qualify without emailing.
  • An easy way to get in touch — Give an easy capture path: short form, booking link, or contact route from the first screen.
  • Answers to the questions people ask before buying — Answer the top 3-5 buyer objections in an FAQ to remove hesitation before the CTA.

Deliverable

The full write-up is ready

We've already done the full work-up for Codex CLI compiled to WASM running in the browser — every fix written out, with copy and code ready to paste. Here's what's inside:

Complete fix plan (every issue, step by step)

1. No obvious button to start

Add a prominent call-to-action that encourages users to start coding immediately.

  1. Put one primary button on the first screen with action text (e.g. the suggested CTA below).
  2. Repeat the same CTA after the proof section and in the footer.
  3. Make the button visually dominant — one accent colour used only for the primary action.

2. Search engines can’t tell what you sell

Add structured data (LocalBusiness / Organization schema: address, hours, phone, ratings) so search engines show you with rich results.

  1. Add JSON-LD using the schema snippet below, edited with your real details.
  2. Validate it in Google's Rich Results Test before publishing.
  3. Keep it in sync with the on-page facts (name, address, phone, offers).

3. No price anywhere on the page

Include clear pricing information or a free trial offer to entice users to sign up.

  1. Show pricing, packages, or a 'from …' anchor so buyers can self-qualify.
  2. If pricing is bespoke, give a starting price or a typical range.
  3. Pair each price with what's included so it reads as value, not cost.

4. No easy way to get in touch

Simplify the process for users to get support or feedback on their coding experience.

  1. Add a visible booking link, short form, or tap-to-call number on the first screen.
  2. Keep the form to 3 fields max; every extra field drops completion.
  3. Confirm submissions with a clear success state, not a silent reload.

5. AI assistants have nothing to read

Publish /llms.txt with a concise machine-readable product summary, audience, pricing, and docs links.

  1. Publish /llms.txt with a plain-text product summary, audience, pricing and key links.
  2. Keep it concise — answer engines reward clear, factual structure.
  3. Update it when your offer or pricing changes.

6. Search engines have no map of your site

Publish /sitemap.xml and submit it to search engines.

  1. Publish /sitemap.xml listing every indexable URL with <lastmod>.
  2. Reference it from robots.txt and submit it in Google Search Console.
  3. Regenerate it automatically whenever pages change.

Why it matters

The fastest developers 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.
