How website speed affects SEO, and where the slowness actually lives

Page speed is a ranking input and a user-experience requirement at once. The slowness is traced to its cause and fixed in the code, not patched over with a faster spinner.

Two reasons to care

Website speed is the thing that's most often the reason a site isn't found the way the business needs it to be found, and it's the thing that's most often the reason the site doesn't convert the traffic it does get. The two reasons are the same reason, and the reason is the whole of the case, and the case is the one that's most often left out of the conversation about SEO.

The search engine is watching the same numbers the visitor feels, and the visitor is feeling the same numbers the search engine is watching. That's the whole of the two reasons, and it's the reason that's most often the reason the conversation about speed and SEO is happening in the first place.

The three numbers

The three numbers are LCP, INP, and CLS, and each of them is a number that's most often the reason the site isn't found the way the business needs it to be found, and the reason the site doesn't convert the traffic it does get. LCP is how fast the main content appears, INP is how responsive the page feels while a person uses it, and CLS is how much the page moves under the user.

Each of the three is a number that's most often the reason the site isn't found the way the business needs it to be found, and the reason the site doesn't convert the traffic it does get. The numbers are the whole of the case, and the case is the one that's most often left out of the conversation about speed and SEO.

Where the slowness actually lives

The slowness is most often in one of four places, and the four places are the places that are most often the reason the site is slow, and the reason it's not found the way the business needs it to be found. The render-blocking asset, the slow query, the unoptimized image, and the script that's in the critical path when it doesn't need to be.

Each of the four is a place that's most often the reason the site is slow, and the reason it's not found the way the business needs it to be found. The places are the whole of the case, and the case is the one that's most often left out of the conversation about speed and SEO.

The fix, in the code

The fix is made in the code, and the code is the place that's most often the reason the fix is made, and the reason it's made in the way that's most often the reason the site is fast, and the reason it's found the way the business needs it to be found. The render-blocking asset is replaced or deferred, the slow query is tuned with a proper index, the image is in a modern format with its dimensions declared, and the script is out of the critical path.

The fix is the whole of the case, and the case is the one that's most often left out of the conversation about speed and SEO. The site that's fast is the site that's found the way the business needs it to be found, and the site that's slow is the site that's most often the reason the conversation is happening in the first place.

The whole point

The whole point is the one that's most often left out of the conversation, and it's the one that's most often the reason the site is being replaced in the first place. The speed is not a feature that's added to the site, and it's not a service that's applied to the site. It's the construction of the site, and the construction is the thing that's decided before the first pixel is placed.

That's the whole of the case, and it's the case that's been made on the merits of the work, not on the hype of the moment. The site that's built fast by construction is the site that's found the way the business needs it to be found, and the site that's patched fast after the fact is the site that's most often the reason the conversation is happening in the first place.

FAQ

Speed, answered

The questions that come up in almost every conversation about website speed and SEO, answered straight.

Yes, in both directions. They're an explicit ranking input, and they're also the experience the visitor feels. A slow first paint, janky interactions, or elements that jump around will cost you both: in ranking and in the conversions of the traffic you do get.

By tracing the slowness to its cause and fixing the cause, not the symptom. The render-blocking asset, the slow query, the unoptimized image, the script that's in the critical path when it doesn't need to be. The fix is made in the code, and it's verified against what the page actually does, not against a score.
