What conversion rate optimisation agencies do and how Seatext can help

Conversion rate optimisation (CRO) agencies specialise in increasing the percentage of website visitors who become customers by testing, copy tweaks, and data‑driven tweaks. They use tools and processes—often AI‑driven—to rewrite headlines, offers, and CTAs,...

Direct answer

Conversion rate optimisation agencies are firms that focus on turning more of your site’s traffic into leads or sales. They do this by analysing visitor behaviour, rewriting copy, running controlled A/B tests, and eliminating invalid traffic that skews performance data.

Typical CRO process

  1. Data collection: Gather click, scroll, and conversion data from analytics and ad platforms.
  2. Hypothesis generation: Identify high‑impact elements (headlines, CTAs, product descriptions) that could be improved.
  3. Variant creation: Produce small copy or layout variations, often using AI to generate multiple options.
  4. Testing: Deploy the variants to a portion of traffic and measure lift in conversion metrics.
  5. Roll‑out: Promote the winning variant to all visitors while keeping the original version for fallback.

Common mistake

Running large‑scale redesigns without first establishing a baseline can mask true performance gains. CRO agencies start with high‑traffic, intent‑rich pages and make incremental, measurable changes.

Verification step

After a test finishes, compare the statistical confidence of the lift against the pre‑test baseline. Only roll out changes that meet a predefined confidence threshold (e.g., 95%).
