Agencies love selling full websites. Sometimes a $2K landing page outperforms a $20K site - and sometimes the reverse burns money.
The short answer
Build a landing page when you're validating one offer, running one campaign, or need speed this week - focused pages convert 2-4x better than homepage visits for paid traffic. Build the full website when organic growth, catalog breadth or trust depth is the bottleneck. Sequence matters: validate with landing pages, then invest the site in what converted.
One page, one job, one conversion
Best for: Paid campaigns, offer validation, lead-gen with a single CTA
Typical cost: Fixed-price, shipped in days
The permanent asset
Best for: SEO programs, multi-product catalogs, trust-heavy considered purchases
Typical cost: Bigger upfront investment; compounding returns

Our verdict
Our standard sequence: landing pages prove the message, the website industrializes it. Astrix Gym tripled trial memberships on a single objection-crushing page before we ever touched their site - validation first, infrastructure second.
Partially - modern sites handle many campaigns. But paid traffic converts best when the entire page mirrors the ad's promise and audience. High-volume campaigns always deserve dedicated pages.
Landing pages ship in about a week including copy and tracking. Full conversion-focused sites run 2-4 weeks for most builds; Afterfyve's store rebuild went live in three.
