Direct answer: A landing page can be enough when one campaign has one clear offer, one audience, one conversion action, and the existing website is otherwise credible. A broader website rebuild may be warranted when the site is slow, thin, confusing, poorly tracked, missing service pages, or short on trust evidence. NerdBrainz planning ranges include landing-page and CRO work around $1,000 - $5,000+/mo, tracking around $2,500 - $5,000+, Google Ads management around $750/mo retainer + 15% of ad spend, and website work such as $4,000 - $10,000+ or $10,000 - $25,000+ when the foundation needs replacement.
Google Ads performance depends on relevance, landing-page experience, conversion path, and measurement. A focused landing page can improve one campaign quickly, but it cannot fix a weak brand site, broken service architecture, missing proof, poor follow-up, or a tracking system that cannot show which leads matter.
Prices shown are non-binding planning estimates for budgeting only. They are not guaranteed pricing, a contractual offer, or a promise to perform work for the listed amount. Final scope, timeline, deliverables, and pricing require a discovery conversation, review of project materials and technical requirements, a written proposal or statement of work, and a signed agreement. Third-party costs, ad spend, taxes, rush work, integrations, content readiness, revisions, and technical complexity can change the final price.
