Is your text actually readable?
Accessibility is a ranking-adjacent signal and a legal consideration in many markets — worth five seconds of checking.
Run a quick text contrast test on buttons, headings and body copy — the WCAG contrast ratio appears as soon as you pick two colors. As an accessibility color checker it shows AA and AAA pass or fail at both text sizes. Treat it as your AA and AAA compliance checker before any design ships.

Frequently Asked Questions
What contrast ratio do I need? ▼
WCAG AA requires 4.5:1 for normal text and 3:1 for large text (18px+ bold or 24px+). AAA pushes to 7:1 and 4.5:1. Aim for AA minimum on body text.
Does contrast affect SEO? ▼
Not a direct ranking factor, but accessibility quality overlaps with user experience metrics Google cares about — and real users literally bounce off unreadable text.
How long does color contrast checker take? ▼
color contrast checker timelines depend on current assets, competition and how quickly content or access is provided. Early signal often appears in weeks; stronger, lead-level results typically take a few months of consistent work. Webinfolink sets a written plan so you know what happens in month one versus later cycles. Review the tools hub for how this service sits with related work.
How much does color contrast checker cost? ▼
Cost is scoped after we see your site, offer and target market. A short audit or sprint is cheaper than an ongoing retainer. We quote ranges with assumptions instead of a fake fixed price. Share your URL on the quote form so we can point to the smallest useful starting package rather than a bloated bundle.
What does Webinfolink need to start? ▼
A live URL (or Figma/brief), the services you sell, locations you serve, and access where implementation is in scope. Competitor names help. If access is delayed we can still audit and sequence fixes. WhatsApp or a call is enough to begin scoping.
Will this work outside Delhi? ▼
Yes. Delhi is our base, but most work is remote across India. Local modifiers are used only when the page intent is local. National or export offers follow a different keyword and landing map.
How do you report progress? ▼
We report the work completed, what changed on the site or campaigns, and the next actions. Metrics follow the channel: rankings and leads for SEO, CPL and qualified enquiries for ads, citations and answer coverage for AEO. You get a simple monthly note, not a vanity dashboard.
Do you guarantee first-page or number-one results? ▼
No. Webinfolink does not sell guaranteed rankings or AI citations. We improve the inputs that typically move visibility and enquiries, then measure honestly. If a channel is a poor fit we will say so before you spend.
