How to start a product review website

A product review site earns trust by doing work readers cannot: buying several products in one category, testing them the same way, and publishing what happened, including the failures. Day to day you buy products, run timed tests, take measurements and photos, write comparisons, update articles when models change, and resell or donate tested units. The main decision is how deep to go in one category before expanding. Shallow reviews across many categories look like everything else online. The real constraint is cash and patience: products cost money upfront, affiliate commissions arrive weeks later, and new pages may take months to be found.

The business in one offer

Who it serves

Readers shopping for a cordless stick vacuum who own pets or live in homes with mixed flooring. They have seen dozens of rankings that read the same, and they want measured data on battery runtime, pet hair pickup and noise from someone who actually used the machines.

What to sell first

One in-depth comparison of six cordless stick vacuums, tested on carpet, hardwood and pet hair with timed battery runs, a noise reading at one meter and photos of bins and brush rolls, plus a short pick for three budgets. Excluded: sponsored placements, manufacturer-provided rankings, robot vacuums and products not tested in person.

A single, carefully tested category gives you original data that generic lists cannot copy, and the same test protocol scales to new models. Readers can see your method, which supports the honest recommendations that affiliate income depends on.

What could it cost to start?

This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.

Illustrative setup allowances · USD
Item to priceExample allowance
Six vacuums bought for testing, net of resale$900.00
Sound level meter and test materials$90.00
Domain and hosting, one year$180.00
Camera tripod and lighting$110.00
Spreadsheet and photo editing tools$60.00
Example total$1,340.00

What this assumes—and excludes

Assumes you test in your own home, write well and can resell tested units at a loss. Excludes owner pay, paid ads, legal review and sales tax on products. Resale values and affiliate commission rates change often, so check them before buying test units.

Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.

How the unit economics work

At an assumed $12.00 per referred sale and $0.80 in direct costs, contribution is $11.20 before monthly fixed costs, owner pay and taxes. With 0.3 all-in working hours per unit, that is $37.33 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.

The example also allows $40.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.

Monthly operating result$72.00

Startup funding gap$1,340.00

Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 3 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.

How to find the first customers

Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.

  1. Publish your testing method on its own page with photos of the test setup, so readers and other sites can see how results were measured.
  2. Share one finding with a pet owner forum or local community group where it is welcome, such as which models handled long dog hair. Link to the review only if allowed.
  3. Contact two independent vacuum repair shops and ask what fails most often. Credit them by name in the article with permission, and ask if they would share it.
  4. Track clicks per affiliate link and update rankings when tests show a new winner, recording the change date in the article.

What to validate before spending more

  1. Read the affiliate program terms carefully, including cookie length, banned placements and rules on stating prices, before you buy test products.
  2. Write your first comparison with three products before buying six, and measure whether readers stay to read the results tables.
  3. Check that your resale plan works by listing one tested unit and recording what it sells for and how long it takes.
  4. Ask someone outside the project to follow your test method from the written page. If they cannot repeat it, clarify the steps.

The operational catch

Manufacturers will offer free units and sometimes payments for placement. Accepting quietly can make your rankings look bought, and accepting a unit with strings attached can bend your conclusions. Disclose free products in the review, refuse pay-for-ranking deals, and buy key products yourself so the core results stay independent.

A practical way to fund the first step

Test three units first, resell them, and use the recovered money for the next three. Keep hosting on a basic plan and avoid buying a studio setup until affiliate income covers product purchases.

Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.

Questions before you start

Do I need to buy every product?

Buying keeps you independent. Borrowing or accepting review units is acceptable if disclosed, but returning units to a brand on request can create pressure. Many reviewers buy at least the top contenders.

How do I disclose affiliate links?

Place a short clear statement near the top of each review, before the first link, saying you earn a commission from purchases. Do not hide it in a footer or behind a tooltip.

Will AI-written reviews work?

Readers come for firsthand testing. AI text without your own measurements and photos adds nothing, and content made mainly to rank in search can violate Google's spam policies.
