What is the SEO Score and Why It Matters
Prerender includes a built-in technical SEO scoring system as part of its rendering and caching process. While this score does not predict your search engine ranking, it’s a powerful tool to surface potential technical issues that can harm your site's visibility on Google and other search engines.
When a page is rendered and cached, Prerender evaluates various on-page SEO elements—such as missing tags, improper meta content, or broken structure—and calculates a score. You can view this score in your cache results and click on it to access a full breakdown of the technical checks.
This feature helps site owners identify broken pages, missing content definitions, or improper configurations early—before they negatively affect performance or SEO.
What the Score Means
-
Scores can be Positive or Negative
Pages start from zero, and technical checks either add to or subtract from the score based on what’s present or missing. -
Color Coding
-
Blue: Positive score (technically healthy)
-
Red: Negative score (issues detected)
-
N/A: Score not yet calculated (page hasn’t been recached yet)
-
-
No “Perfect” Score
The score isn’t meant to hit a target number. Instead, use it to prioritize which pages may need technical improvements.
When Are Scores Generated?
SEO scores are calculated during the recache phase—not on the initial on-demand render. This ensures bots and users receive the fastest response while Prerender evaluates pages in the background.
If a score shows as “N/A,” the page likely hasn’t been recached yet.
💡 Tips & Notes
-
Use the Score to Triage Issues
Sort your cached pages by SEO score to find the lowest-performing ones. These are ideal candidates for debugging and improvements. -
Don’t Aim for Arbitrary Numbers
Focus on the quality of your technical implementation, not reaching a specific score value. -
Scores Reflect Page Markup, Not Search Engine Rank
This feature is diagnostic, not predictive. Use it to ensure best practices are followed. -
Recache Pages to Trigger Scoring
If a page has an "N/A" score, use the Recache API or manually trigger recaching to calculate the score. -
