Why does my government PDF show a yellow question mark?

Indian government PDFs are digitally signed using certificates from NIC, eMudhra, or other CCA India licensed authorities. Adobe Acrobat and most PDF viewers don't include India's Root Certifying Authority (RCAI) in their default trusted certificate store. So even though the signature is completely valid and legally recognised under the Information Technology Act 2000, your PDF viewer shows a yellow question mark because it cannot automatically verify the issuer. Kagazo checks your PDF against the actual CCA India trust hierarchy and gives you a copy with a permanent green tick visible on any device.

Is my document safe? Do you store my PDF?

Your PDF is processed entirely in memory during verification. We never write your file to disk, never store it on our servers, and never share it with any third party. The file is deleted from memory immediately after verification is complete. You can also verify this by checking our open source backend code.

Which documents does Kagazo support?

Kagazo supports any PDF digitally signed under India's CCA certificate hierarchy. This includes e-Aadhaar, PAN card, DigiLocker documents, ITR-V, Form 16, and all state government certificates from Tamil Nadu e-District, AP and Telangana MeeSeva, Karnataka Nadakacheri and eJanma, Kerala Sevana portal, and more.

My Aadhaar PDF is password protected. Will it work?

Yes. Enter your Aadhaar password (first four letters of your name in capital letters followed by your birth year, for example RAMA1995) in the password field that appears after you upload your e-Aadhaar PDF. We decrypt it in memory, verify the signature, and return a verified copy.

What is the difference between "Signature Valid" and "Signature Unknown"?

Signature Valid means the document is genuinely issued by the government authority and has not been modified. Signature Unknown means your PDF viewer cannot verify the certificate chain — this is a viewer configuration issue, not a problem with your document. Signature Invalid means the document may have been tampered with or re-saved after signing.

Does this work on mobile?

Yes. Kagazo is fully mobile responsive and works on any Android or iOS browser. No app installation required. Simply open kagazo.in on your phone browser, upload your PDF and verify instantly.

Key Meta Elements for High Search Click-Through Rates (CTR)

Crafting high-converting snippets requires adhering to search engine and social media standards:

Title Tag (50–60 Characters)

The primary headline displayed in search results and browser tabs. Place your most critical target keyword at the front of the title.

Meta Description (120–160 Chars)

The summary text underneath the title in search engines. Include a clear call-to-action (CTA) to encourage searchers to click.

og:image (1200x630 Pixels)

The recommended standard for Facebook and Twitter summary_large_image cards is 1200x630 (1.91:1 ratio) with a file size under 5MB.

Canonical URL Link

Tells search engines the authoritative URL to rank, consolidating link signals and avoiding duplicate content penalties.

Frequently Asked Questions

What is the optimal character length for a page title?

Search engines like Google generally truncate page titles longer than 60 characters (or ~600 pixels). The optimal length is between 50 and 60 characters to ensure your full brand and keywords are displayed without being clipped.

How long should a meta description be?

The ideal meta description length is 120 to 160 characters. Descriptions longer than 160 characters are typically truncated by Google with an ellipsis (...), while descriptions under 100 characters often underutilize valuable SERP real estate.

Why are Open Graph (og:) tags important?

Open Graph tags determine how your webpage looks when shared across social networks like Facebook, LinkedIn, Twitter, Slack, and WhatsApp. Without valid og:image and og:title tags, links will appear as plain text without preview thumbnails.

What is a canonical tag and why does it prevent SEO penalties?

A canonical link tag (<link rel="canonical" href="...">) indicates to search engines which URL represents the master, primary version of a webpage. It prevents duplicate content dilution when pages can be reached through multiple parameters (e.g. ?ref= or ?sort=).
