Web Article Date Verification SaaS for Investigators
A SaaS tool that automatically verifies the true publication and modification dates of web articles by aggregating multiple independent signals—Wayback Machine snapshots, search engine first-seen dates, CMS metadata forensics (WordPress post IDs, JSON API dates), RSS feed archives, and backlink first-seen data—into a single verification report with a confidence score. Targeted at professional investigators, journalists, and legal researchers who need to detect backdated or modified articles.
为什么这很重要
You are a professional investigator who encounters suspicious news articles that look fabricated or backdated to benefit a client. The publication and modification dates shown on the page are meaningless because anyone with CMS access can set them to whatever they want. To verify the real date, you have to manually check multiple fragmented sources—archive snapshots, search engine caches, WordPress post IDs, RSS feed history—each requiring technical knowledge you may not have. There is no single tool that aggregates these signals into one report, so you spend hours piecing together evidence and still worry you missed something. You need a reliable, easy-to-use tool that produces a professional verification report you can stand behind.
- · 专为 Professional investigators, forensic researchers, journalists, and legal professionals who need to verify the authenticity of web article publication dates for evidence or reporting purposes. 打造。
- · 最可能的变现方式：SaaS subscription with tiered plans (individual investigator vs. team/enterprise)。

MVP 方案 · 1-2 周
- Build core URL analyzer that fetches page HTML and extracts datePublished, dateModified, and JSON-LD metadata

- Integrate Wayback Machine API to fetch earliest available snapshot date for a given URL
- Create simple web UI with URL input field and basic results display showing extracted signals
- Deploy MVP to a staging environment and test against 20 known backdated and legitimate articles
- Add search engine first-seen date integration via Google/Bing API or web scraping of cache data
- Implement RSS/Atom feed archive checking for historical publish timestamps
- Build confidence scoring algorithm that weighs multiple signals and produces a verdict (verified/mismatched/insufficient data)
- Add PDF report export with all evidence sources listed in investigator-friendly format
- Set up landing page with pricing and launch on investigator-focused communities and forums

为什么这件事可能失败
自我反驳——最重要的信任度信号
- 1Usage frequency may be too low for a monthly subscription model—investigators might only need date verification a few times per case, making it hard to justify ongoing payments versus one-time alternatives.
- 2Free tools like Wayback Machine plus manual checks may be 'good enough' for most users, especially if they are technically inclined or have developer colleagues to consult.
- 3API costs from multiple data providers (search engines, archive services, backlink databases) could make each verification report expensive, squeezing margins if users expect low prices.
证据综述
AI 如何合成此洞察——无原话引用
Approximately 10 commenters confirmed that CMS date metadata is trivially fakeable and cannot be trusted as evidence. Multiple users independently recommended checking multiple independent sources—Wayback Machine, search engine caches, RSS feeds, WordPress post IDs, and backlink first-seen dates—but noted this requires significant technical knowledge and manual effort. One commenter confirmed the WordPress post ID technique worked well for their investigation, and the original poster asked for simplified explanations, underscoring the gap between available technical methods and accessible tools for non-developer professionals.
