Why website performance matters for local SEO in 2026
Google has used Core Web Vitals as an explicit ranking factor since 2021, and the weight of those signals has increased every year. In 2026, a service business with a Performance score below 50 on mobile loses meaningful ranking ground to faster competitors — even if the slower site has stronger content and links.
Beyond rankings, performance directly impacts conversion: a one-second delay in mobile load time reduces conversion rate by 12 to 25 percent in service business niches. Performance is one of the few SEO investments that pays back twice — better rankings and better conversion on the visitors you already get.

Frequently asked questions
How long does a performance optimization project take?
Two to three weeks for most websites. Sites built on WordPress with many plugins or sites with complex JavaScript take closer to four weeks. We provide weekly progress updates with interim Lighthouse scores so you can see improvement as it happens.
Will you break my website during the optimization?
No. We work in a staging environment and test exhaustively before pushing changes to production. We also keep a rollback path active for the first two weeks after launch. We have never caused a production outage in client engagements.
Do you guarantee a 90+ Lighthouse score?
We guarantee an 85 or higher Performance score on mobile, which is the threshold Google rewards. Hitting 90+ depends on factors outside our control (server quality, third-party scripts the business cannot remove). If we cannot get to 85, we refund the project.
What if my Core Web Vitals are already good?
Then you do not need this service. Our free audit will tell you within 60 seconds whether you need performance work. About one in eight businesses we audit is already in the green and we tell them honestly.
