Depends on what the right thing is in your specific context. If you drop from 100% to 98% but increase your conversion rate 5x, the trade off should be obvious.

Depends on what the right thing is in your specific context. If you drop from 100% to 98% but increase your conversion rate 5x, the trade off should be obvious. From my experience anything 95% or better is basically perfect. Although stuff like "time to first byte" might impact the number of pages crawled when you have millions of pages etc. There will always be edge cases. The article makes a funny point, but I'm not sure it is a practical one. Who would honestly go through those steps? Maybe someone copy-pasting or installing templates could make a few of those errors? Overall the score is helpful and the specific errors detected are always visible in the breakdown below the score. As with anything if you don't understand the underlying technology, tooling and metrics can be troublesome. In those cases, a simple score is still better than giving a novice developer a complex breakdown.
