Plan Options and How to Find the Best Plan

Overview

Choosing the right Prerender.io plan depends on how many page renders your site requires per month. To help your site grow without hitting limitations, Prerender plans are designed with a flexible render budget—including both a fixed monthly quota (Reserved Computation) and overage support (On-Demand Computation).

This guide will help you estimate your render volume and select a plan that supports both your traffic and SEO refresh needs.

Detailed Explanation / How It Works

Reserved vs. On-Demand Computation

Reserved Computation: The number of renders included in your monthly plan.
On-Demand Computation: Renders beyond your monthly limit—billed at an additional cost to ensure seamless content delivery.

Whether you expect stable or spiking usage, our subscription model ensures your content stays prerendered without interruption.

Factors That Influence Render Volume

Number of URLs
Cache Expiry Interval
Mobile Optimized Rendering
Uncontrolled Crawling and Indexing
Dead Links or Forwarding Internal URLs to Prerender
Manual Recaching via API
Bot Requests to Error Pages (404s, 503s, etc.)

Step-by-Step Usage: Estimating Monthly Renders

1. Determine the Number of URLs

Use your sitemap or tools like Google Search Console (Indexing → Pages) to view total URL count.

2. Double for Mobile and Desktop Versions

We render both versions to ensure full SEO coverage. Multiply your count by 2.

3. Choose a Cache Freshness Interval

This refers to how often you want each page refreshed (e.g., every day, every 5 days, every 14 days).

4. Plug into the Formula

(NUM_CACHED_URLS / CACHE_EXPIRATION_DAY) × 2 × 30

Example Scenarios

Daily Refresh
(1,000 / 1) × 2 × 30 = 60,000 renders per month
Refresh Every 5 Days
(1,000 / 5) × 2 × 30 = 12,000 renders per month
Refresh Every 14 Days
(1,000 / 14) × 2 × 30 ≈ 4,285 renders per month

*This is an estimate. Your actual usage may vary due to URL parameters, crawl frequency, and bot behavior.

Common Pitfalls / Tips

If your site receives a lot of bot traffic to changed URLs or error pages, your render count may spike unexpectedly.
Upgrade to a plan with enough Reserved Computation to avoid higher charges from repeat On-Demand usage.
