How Rank Math SEO – AI SEO Tools to Dominate SEO Rankings Affects Your WordPress Speed
How is this scored?
Our Benchmark Methodology
Every speed score on MakeWPFast is based on real performance measurements, not estimates. We install each plugin on a clean WordPress 6.9 setup (PHP 8.3, MariaDB, GeneratePress theme) and measure the difference in three metrics:
TTFB (Time To First Byte) — how many milliseconds the plugin adds to server response time. This is the most important factor (50% of the score) because it directly affects every page load.
Memory usage — how much additional PHP memory the plugin consumes per request (30% of score). High memory usage can cause crashes on shared hosting.
Database queries — how many extra SQL queries the plugin runs per page load (20% of score). More queries mean more database work on every request.
| Grade | What it means |
|---|---|
| A / A- | Negligible impact. Safe to install on any hosting. |
| B+ / B / B- | Light impact. Adds some overhead but manageable on most setups. |
| C+ / C / C- | Moderate impact. May noticeably slow down budget hosting. |
| D+ / D | Heavy impact. Will affect page load times. Consider alternatives. |
| F | Severe impact. Significant resource usage that hurts performance. |
Plugins marked "Not Yet Tested" have not been benchmarked yet. We do not estimate or guess scores — if there is no measured data, there is no grade.
Note: Benchmarks measure a plugin in isolation on a clean install. Real-world impact varies based on your hosting, other plugins, and how the plugin is configured.

Performance Analysis
Rank Math SEO is a WordPress SEO plugin that bundles features like Google Search Console integration, redirection handling, schema markup and core SEO tools in one interface. It’s aimed at developers and site owners who want a single solution rather than juggling multiple plugins.
For developers who need reliable performance, the benchmark shows a modest 8 ms slower target‑time‑to‑first‑byte and no extra memory usage, so it won’t add noticeable overhead. However, it does add roughly ten additional database queries per request, which could be a small cost for the functionality.
If you’re looking for a zero‑impact SEO plugin with no noticeable slowdown, this one may not be the best fit. The plugin is well‑received, with a near‑perfect score and thousands of users, but its extra queries mean it’s not ideal for sites where every micro‑second and every query matters.
Maintenance Status
