## Description

VariantFlow is a blazingly fast, zero-bloat A/B testing tool built natively for 
the WordPress Gutenberg editor. Instead of relying on heavy third-party SaaS platforms
or bloated plugins that ruin your site speed, VariantFlow runs entirely within your
WordPress dashboard.

Major Features:
 * **Native Gutenberg Experience:** Design your Variation A and 
Variation B directly inside the block editor. No external builders. * **100% Cache
Compatible:** The plugin uses a lightweight client-side script (< 1kb) to randomize
variations, guaranteeing it works perfectly with WP Rocket, LiteSpeed Cache, W3 
Total Cache, and any host-level page caching. * **Zero Performance Hit:** The tracking
REST API endpoint is asynchronously called, ensuring your page load speed is never
affected. * **Clean Analytics:** View a beautifully designed, minimal dashboard 
right in your WordPress admin to see Views, Clicks, and Click-Through Rates (CTR).***
Smart Winner Declaration:** Set a custom “Minimum Views” threshold (e.g., 50 or 
100 views) before the plugin automatically highlights the statistically winning 
variation, preventing false positives. * **Privacy Focused:** Stores data securely
in your own database. No tracking pixels, no third-party data sharing.

### Common Use Cases

Not sure what to test? Here are a few ways VariantFlow can instantly increase your
conversions:
 * **Call-to-Action (CTA) Buttons:** Test “Buy Now” vs. “Add to Cart”
or “Get Started” vs. “Learn More”. See which text generates more clicks. * **Pricing
Pages:** Test displaying a monthly pricing table vs. an annual pricing table to 
see which yields a higher click-through rate to your checkout. * **Landing Page 
Headlines:** Write two drastically different H1 headlines for your sales page to
see which hooks more readers into clicking your links. * **Lead Generation Forms:**
Test a short, simple form against a longer form with more details to find the sweet
spot for email signups.

## Installation

 1. Upload the `variantflow` folder to the `/wp-content/plugins/` directory, or install
    the ZIP file via the WordPress Plugins menu.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Open any page or post and add the “A/B Test Container” block.
 4. Design your “Variation A” and “Variation B” by dropping text, images, or buttons
    into the respective sections.
 5. Publish the page! Go to the “A/B Tests” menu in your WordPress dashboard to monitor
    your live conversion rates.

## FAQ

### Does this work with my caching plugin?

Yes! VariantFlow was built specifically to solve the caching problem. It delivers
both variations in the initial HTML and uses an ultra-lightweight client-side script
to instantly hide the losing variation before the user sees it. It works seamlessly
with any caching setup.

### Do I need React or coding knowledge?

No. You use standard Gutenberg blocks to build your variations natively.

### Where is the data stored?

All analytics data is stored securely in your own WordPress database in a custom,
lightweight table (`wp_ab_test_stats`). We do not use the bloated `wp_postmeta` 
table.

### How does the plugin decide which variation wins?

The plugin calculates the Click-Through Rate (CTR) for both Variation A and Variation
B. However, to ensure statistical accuracy, you can set a global “Minimum Views”
threshold in the A/B Tests dashboard. The plugin will only declare a winner in green
once a variation hits that minimum threshold, preventing a variation with 1 view
and 1 click from instantly winning.

### Will this slow down my website?

Absolutely not. The frontend code is less than 1kb of vanilla JavaScript, and the
backend tracking occurs asynchronously via the WordPress REST API. It is designed
to be completely invisible to your site’s performance metrics.

### Can I test more than two variations?

Currently, VariantFlow is designed strictly for A/B testing (two variations) to 
keep the plugin as lightweight and easy to use as possible.

I think this is a great idea and a really solid start. I like that you’re keeping
a simple, native Gutenberg feel.
