    Calculate Your
    Prerendering ROI

    Estimate how much organic traffic you could gain by fixing JavaScript rendering issues with prerendering.

    The Problem

    JavaScript sites often have only 30-50% of their pages properly indexed by Google. That's potentially half your content invisible to search engines.

    The Opportunity

    Prerendering can boost indexing rates to 90-100%. More indexed pages means more organic traffic, more visibility, and more revenue.

    What Affects Your ROI

    Key factors that determine how much you'll gain from prerendering

    Current Indexing Rate

    The lower your current indexing rate, the more you stand to gain. Check Google Search Console to see how many of your pages are indexed.

    Content Quality

    More indexed pages only helps if those pages have valuable content. Focus on pages that target real search queries with good content.

    Competition Level

    In competitive niches, getting your content indexed is just the first step. But you can't rank if you're not even in the index.

    Frequently Asked Questions

    What is prerendering and how does it help SEO?
    Prerendering is a technique that generates static HTML versions of your JavaScript pages before search engines crawl them. This ensures Google and other search engines see your fully-rendered content immediately, rather than waiting for JavaScript to execute. For JavaScript-heavy sites, prerendering can dramatically improve indexing rates.
    How do I find my current indexing rate?
    Check Google Search Console under 'Pages' or 'Coverage' report. Compare the number of 'Valid' (indexed) pages to your total indexable pages. If you have 100 pages but only 40 are indexed, your indexing rate is 40%.
    What's a typical indexing improvement with prerendering?
    JavaScript sites often see their indexing rates jump from 30-50% to 90-100% after implementing prerendering. The exact improvement depends on how JavaScript-heavy your site is and how well Google was previously able to render your content.
    Is prerendering better than SSR for SEO?
    Both can achieve excellent SEO results. Prerendering is often easier to implement for existing client-side apps since it doesn't require code changes. SSR requires more architectural changes but can offer better performance for dynamic content. Use our SSR vs Prerendering comparison tool to find the best fit for your stack.
