Who we are
Marvellous Performance Marketing Agency, Lagos, Nigeria. hello@marvellousperformance.com
Our free tools
The tools at /tools/ are provided free and without warranty.
They are calculators and checks, not advice. Their outputs depend entirely on what you enter. We do not verify your inputs and cannot know whether they are accurate.
The Ad Waste Estimator produces a modelled range, not a measurement. It is derived from your answers to four structural questions and from percentages based on our own client work cross-checked against published benchmarks. It has not seen your account. The page says this and we mean it: do not treat the figure as an audit finding.
The Landing Page Check reads HTML only. It fetches the page once and reports what a crawler would receive. It does not render the page, run JavaScript, or assess design, speed as experienced by a visitor, or whether your tracking actually fires. Anything it reports as absent may simply be invisible from outside.
By using the Landing Page Check you confirm you are entitled to request a check of that address. We fetch the public homepage once, and cache the result for fourteen days.
The Growth Audit
The Growth Audit produces a score and a written diagnosis from your answers. It is a diagnostic tool, not a professional audit, and does not constitute marketing, financial or legal advice. Any figures it produces about wasted spend are modelled ranges based on your answers, not measurements of your accounts.
Our services and pricing
Prices shown on the site are indicative and may change. Go Digital packages are priced in Naira; Growth OS is priced in US dollars. Recruitment fees are a percentage of first-year salary as stated on that page. Nothing on this site is an offer capable of acceptance; engagements begin with a signed agreement.
We work with businesses spending $2,000 per month or more on marketing. Our tools and forms reflect that, and below that threshold we will say so rather than take a call.
No guarantee of results
Past results shown in our portfolio were achieved for specific clients in specific conditions. They are not a prediction. Marketing performance depends on factors outside our control, including your product, pricing, market and platform behaviour.
Intellectual property
The content, design, tools and written material on this site belong to us. Case-study figures are published with client consent. You may share and link to our pages; you may not reproduce substantial parts of them commercially without permission.
Results pages from the Landing Page Check have shareable links. Those links are not indexed by search engines and are intended for the person who ran the check.
Acceptable use
Do not use the site to break the law, attempt to gain unauthorised access, overload it, scrape it at scale, or run the Landing Page Check against addresses you are not entitled to check. We rate-limit that tool and block requests to private and internal addresses.
Liability
The tools and the Growth Audit are provided without warranty, and what they produce depends on the information you give them. They are not advice, and decisions you take on the basis of their output are your own.
Nothing on this page removes or limits any right you have under the laws that apply to you.
Governing law
We operate from Lagos, Nigeria. If something on this site has gone wrong for you, email hello@marvellousperformance.com and we will try to resolve it with you directly. Where the law of your own country gives you rights as a consumer, those rights continue to apply.
