OG tag fixer and Open Graph checker
Fix broken OG tags before your next link gets shared.
Fixheader shows you why a shared link preview looks wrong in iMessage, Slack, and other unfurls, then gives you corrected metadata and deploy-ready output so the next share looks branded, clear, and trustworthy instead of broken.
- Acts like an Open Graph checker for broken preview issues
- Explains why OG tags are not working on real shared links
- Generates corrected head and full HTML output you can ship

status=200
issues=4
builder=Webflow
- Missing OG tag: og:site_name
- Duplicate OG tag: og:title
- Ordering issue detected

Built for lean product teams
CLI-first and automation-friendly
Focused on preview quality, not generic SEO fluff
Preview proof
Show the exact broken-preview problem before anyone has to read what an Open Graph checker does.
This is the story the product needs to tell in seconds: a shared link looks generic, low-trust, and unfinished before the fix, then becomes branded, clear, and clickable after it.
Before
iMessage link preview
Take a look at the new page:
example.com
Untitled Page
No branded image. Generic title. Missing context. Easy to ignore.
- Missing or weak Open Graph tags
- Generic title and unhelpful description
- No compelling image for the share
After
iMessage link preview
Now it looks launch-ready:

Clear headline. Branded OG image. Immediate trust and context.
- Strong title, description, and branded preview image
- Metadata ordered for better scraper reliability
- A better share surface for launches, texts, and outreach
Use this in advertising
The before-and-after preview is not just a website section. It should be the backbone of your ads, demos, outbound messages, and launch content because it makes the value obvious without asking people to understand metadata first.
What it does
Fix the OG tags and metadata that control what people see before they ever click.
Open Graph checker, not blind debugging
See exactly why a link preview looks weak: missing Open Graph tags, duplicate metadata, bad ordering, and image problems in one clear report instead of digging through raw HTML by hand.
Deployable fixes, instantly
Get corrected <head> output and a corrected full HTML page so you can ship the
fix immediately instead of handing your team another vague warning.
Built for real preview failures
Catch the messy real-world stuff too: builder interference, redirects, weak og:image setups, and metadata that appears too low in the document for scrapers to trust.
Workflow
From broken preview to corrected output in three steps.
Audit a URL
Point Fixheader at a page and fetch the live head metadata with redirect awareness.
Inspect the issues
Review missing tags, builder interference, media validation, and ordering problems.
Ship the correction
Use the corrected head or full page output to patch the live site or deployment pipeline.
Who it is for
Lean teams that need previews to look professional without building a whole SEO stack.
Agencies
Audit client pages quickly and prove what is broken before launch or handoff.
Founders
Catch metadata problems before a launch post, DM share, or press mention falls flat.
Operators
Use JSON output and corrected HTML in QA, CI, or repeatable site-fix workflows.
Built for real operations
A focused tool with a narrow job, clear workflow, and human support behind it.
Operator-first product
Fixheader is built around a practical workflow: inspect a URL, see what is broken, and generate corrected output you can actually ship.
Early-access support
Early users get direct support, a growing FAQ base, and product updates shaped by real metadata and preview problems.
Business-ready foundation
The launch setup includes formal onboarding, support workflows, and a plan for licensing, billing, and international sales.
FAQ
The first questions most people ask.
Does Fixheader host my site?
No. It audits your page and generates corrected output you can deploy through your existing stack.
Is it only for iMessage or can it help with LinkedIn, Facebook, and WhatsApp previews too?
No. iMessage is a strong use case, but the metadata checks are useful for rich previews more broadly.
Do I need to understand raw HTML?
Not deeply. The goal is to translate head metadata problems into a report and corrected output you can use.
Can this fit into automation or CI?
Yes. The CLI already supports JSON output and quiet mode, which makes it easier to plug into tooling.
