How to Improve Your Post-Click Experience (Mobile, Performance, Accessibility, Coherence)

Post-click is the dimension visitors notice without naming. A page that loads in 6 seconds, breaks on mobile, fails screen readers, or contradicts the ad they clicked is a page they leave — not because of any single signal, but because every signal compounds.

About 50-70% of B2B SaaS traffic is mobile. Mobile-first design plus performance optimization plus accessibility plus coherence is the four-leg stool. Skip any one and the page wobbles.

Step 1 — Test on a real mobile device at 390px

Open the page on an actual iPhone (or Chrome devtools at 390x844). The visible viewport above the fold is about 600 vertical pixels. Verify the four fold elements (headline, sub, CTA, one proof anchor) all fit.

Common failures: hero image fills the entire mobile fold; navigation menu pushes the headline below the fold; CTA button is wider than 100% of the viewport (visible but unusable); text-on-image hero becomes illegible.

Fix the layout before optimizing performance. A fast-loading page that breaks on mobile still loses the visitor.

Step 2 — Run PageSpeed Insights and fix the LCP element

Open PageSpeed Insights. Run your URL on Mobile. Note the LCP (Largest Contentful Paint). Target: under 2.5 seconds — the Core Web Vitals "Good" threshold. Anything over 3 seconds loses visitors before they see your content; the share lost scales with each additional second.

PSI tells you which element is the LCP. Usually it is the hero image or a web font. For images, switch to AVIF or WebP (50-70% smaller than JPG). For fonts, subset to only the characters actually used and self-host them.

Step 3 — Audit with axe or Lighthouse

Run an accessibility audit via Lighthouse, axe DevTools, or WAVE. Fix every "critical" and "serious" violation. WCAG AA is the floor for B2B SaaS.

Common high-impact issues: insufficient color contrast on the CTA, missing alt text on images, form labels not associated with inputs, headings out of order (h3 before h2). Each affects screen-reader users and — unrelated but coincident — each often correlates with conversion drops for sighted users too.

Step 4 — Verify destination coherence

For each ad or external link pointing at the page, trace what it promised. Open the page. Does the first viewport deliver that promise?

If the ad said "AI-powered email validation in 30 seconds" and the page hero says "The modern way to send mail at scale," the promise broke. Visitors arrived expecting one thing and got another. They bounce at a substantially higher rate than they would on a page that delivers the ad's promise.

Lytms’s destination-coherence module scores this directly. Mismatches surface as findings with the specific copy gap.

Step 5 — Defer non-critical scripts

Open your page source. Count the third-party scripts loaded before the hero renders: analytics, A/B testing, chat widgets, marketing automation, session replay. Each adds 200-800ms.

Defer everything that does not need to run before first paint. Add `defer` or `async` attributes. Move chat widgets to load on user interaction. Inline above-the-fold CSS so the page renders without waiting for the stylesheet.

Step 6 — Re-score and ship

Run the page through Lytms. Confirm Post-click moved up. Ship to production. Monitor real-user metrics (RUM) over the next two weeks because synthetic tests like PSI sometimes diverge from what real users experience on real networks.
