Priorities

Top Leaks To Fix 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

Structured data

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

02

AI-readable llms.txt

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

03

Clear page title

Make the page title more descriptive to highlight the unique benefits of SpreadsheetPreview.

04

Fast initial response

Speed up the homepage — most developers arrive on a phone, and a slow first load loses them before the page shows.

05

Open Graph metadata

Add Open Graph tags so shared links render with a clear title and value proposition.

06

Sitemap present

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

07

Robots file present

Publish /robots.txt with a sitemap reference and no accidental blocking.

Conversion evidence

How The Page Sells

6 of 8 of the buying-decision signals we could verify are on your site today. The page already shows 6 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 4 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: “PDF.js for spreadsheets.”
  • Action-oriented primary CTA — found: “Start free” (on /pricing)
  • Risk reversal (trial / guarantee / no card) — found: “Start free” (on /pricing)
  • Visible pricing / 'starting at' anchor — found: “Pricing”
  • Easy lead-capture path — found: “contact us” (on /pricing)
  • Objection handling (FAQ) — found: “FAQ”

Highest-impact additions to sell more

  • Social proof (testimonial / customers / rating) — Add a testimonial, customer logo, star rating, or an 'N customers' proof point near the top.
  • Specific, quantified result — Add a concrete number (result %, time saved, customers served). Specifics convert better than adjectives.

Deliverable

Your complete fix pack is ready

We've already done the full work-up for spreadsheetpreview.com — 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. Structured data

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).

2. AI-readable llms.txt

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.

3. Clear page title

Make the page title more descriptive to highlight the unique benefits of SpreadsheetPreview.

  1. Write a 50–60 character <title> in the format: Primary outcome for [audience] — [Brand].
  2. Put the most-searched term first; keep the brand at the end.
  3. Make every important page's title unique — never reuse the homepage title.

4. Fast initial response

Speed up the homepage — most developers arrive on a phone, and a slow first load loses them before the page shows.

  1. Compress and lazy-load images; serve modern formats (WebP/AVIF).
  2. Put the site behind a CDN and enable caching of static assets.
  3. Defer non-critical JavaScript so the first screen paints fast.

5. Open Graph metadata

Add Open Graph tags so shared links render with a clear title and value proposition.

  1. Add og:title, og:description, og:image and og:url to <head>.
  2. Use a 1200×630 share image with the value proposition baked in.
  3. Test the preview with the Facebook/LinkedIn debuggers.

6. Sitemap present

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.

7. Robots file present

Publish /robots.txt with a sitemap reference and no accidental blocking.

  1. Publish /robots.txt that allows crawling and points to your sitemap.
  2. Double-check you are not accidentally Disallow-ing the whole site.
  3. Remove any leftover 'Disallow: /' from staging.

Action order

48-Hour Fix Plan

  • Add structured data (LocalBusiness / Organization schema: address, hours, phone, ratings) so search engines show you with rich results.
  • Publish /llms.txt with a concise machine-readable product summary, audience, pricing, and docs links.
  • Make the page title more descriptive to highlight the unique benefits of SpreadsheetPreview.
  • Speed up the homepage — most developers arrive on a phone, and a slow first load loses them before the page shows.
  • Add Open Graph tags so shared links render with a clear title and value proposition.

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.
