Site Performance Optimization

Poor site performance causes conversions to erode, costs to compound quietly, paid traffic costs to rise, and the gap to grow. A lost conversion isn’t just a lost order. It’s the repeat purchase that never happens, the email that never fires, and the subscription that never starts. It’s a lifetime of spending that never begins. The proof is in the numbers.

• Sites with poor Core Web Vitals (CWV) lost 23% more organic traffic.
• 2-second page load: 9% of visitors leave before engaging. 5-second page load: 38% leave before engaging.
• Google found 24% less abandonment on CWV-passing shopping sites.
• 0.1s improvement = +8.4% conversion, +9.2% AOV
• Returning customers buy 2-3x more frequently. Every conversion lost to slow performance is a repeat buyer who never enters the cycle.

Aries prioritizes your highest-ROI fixes, so you see immediate results.

Every commerce team agrees that site performance optimization matters, yet your team has pushed the performance sprint three quarters in a row. This is not due to a lack of willpower or doubt about the ROI, but rather to a structural pattern that consistently blocks it.

• Performance is always the first thing cut when bandwidth is maxed out.
• Sites that aren’t actively maintaining performance lose ground over 12-18 months. The site gets slower one decision at a time, and no single decision is the problem.
• It’s specialized work. Performance optimization follows a different pattern than feature development.
• Teams assume that doing it internally is cheaper. The math rarely supports that when you account for the full cost.

Aries provides you with a tailored plan to improve performance metrics and the engineering expertise to own that work without compromising your roadmap.

We packaged our Site Performance Optimization offering that fixes your critical storefront performance bottlenecks through a zero-interruption, eight-week engagement that plugs leaked conversions and protects customer acquisition costs without compromising your roadmap.

The plan includes a baseline scan of your Core Web Vitals (CWV), competitor benchmarks, and a prioritized backlog determined with your team in the room. Aries’s dedicated experts own the optimization work with sprint-based fixes through your pipeline, checkpoint scans at every release, a final report with before-and-after evidence, and a 30-day Chrome User Experience (CrUX) follow-up to confirm the gains hold in the real world.

Our engagement uses four phases: Audit & Plan, Execution, Validation, and Follow-Up. Your engineers approve the plan and PRs throughout the eight weeks. Aries Solutions does the rest. Your roadmap stays on target. You reap the benefits.
