It reads, it does not write
The checker uses word lists and Google's published guidance, not AI. It cannot tell whether you really tested the product, so answer the questions honestly.

About the Product Review Content Checker
Paste a product review or a "best" list, as plain text or HTML, and answer five Yes / No / Not sure questions. The checker tests it against Google's "Write high quality reviews" guidance: a user's point of view, evidence of real use, measurements, what sets the product apart, other options, benefits and drawbacks, earlier models, buying factors and, for lists, why each pick won. It also finds affiliate-looking links without rel="sponsored", links to only one seller, and a missing or late disclosure. Each point is marked as Google's guidance or our check, with a score from our checklist and the fixes to make first. It runs in your browser with word lists, not AI, and your review is not uploaded.
How it works
-
01
Paste the review, ideally the HTML from your editor's code view so we can see images and links, and answer the five questions. Press Try an example to see a sample "best water purifiers" list.
-
02
Read the score and the fixes to make first, then each point from Google's guidance, the link and disclosure checks and our own checks.
-
03
Add what is missing from your own testing, mark affiliate links with rel="sponsored", move your disclosure to the top, then paste the review again.
What Google asks of reviews
Google's "Write high quality reviews" page asks reviewers to evaluate from a user's perspective, show evidence of their own experience such as photos or audio, share quantitative measurements, explain what sets a product apart, cover comparable options, discuss benefits and drawbacks from their own research, describe how it has changed from earlier models, and focus on the factors that matter when buying. For "best" lists it asks you to say why each pick is the best, with first-hand evidence, and to give each pick enough to stand on its own.
Affiliate links and disclosure
Google asks sites to qualify affiliate links with rel="sponsored"; "nofollow" is still accepted for this. Its spam policies call affiliate pages whose product descriptions and reviews are copied from the merchant, with nothing added, thin affiliation. Google also suggests links to more than one seller. In India, ASCI counts free products and commissions as a material connection to disclose upfront, and the Department of Consumer Affairs says people must not endorse what they have not used or checked.
What this tool cannot do
It reads your words and links: it cannot tell whether you really tested the product or whether your numbers are right, so your answers to the questions count. It finds testing phrases, measurements and drawbacks with word lists in English, Hindi and Hinglish, so it can miss some. The thresholds and the score are our checklist, not a Google score, and following the guidance does not guarantee rankings.
Frequently asked questions
Does Google penalise affiliate links in reviews?
Affiliate links are allowed. Google asks sites to qualify them with rel="sponsored", whether they were added by hand or by a plug-in, and "nofollow" is also accepted for this. What Google's spam policies call thin affiliation is a page with affiliate links where the product descriptions and reviews are copied from the merchant with no original content or added value.
How long should a product review be?
Google does not set a length. It says to focus on the quality and originality of reviews, not their length, and to follow as many of its best practices as you can. For "best" lists it asks that each pick has enough useful content to stand on its own; this tool flags picks under 80 words, which is our own measure.
Do I need to show my own photos?
Google asks for evidence of your own experience, such as visuals, audio or other links, to support your expertise and the authenticity of the review. Your own photos of the product in use do that; the brand's images do not. Measurements from your own testing help too.
Should I link to more than one shop?
Google suggests considering links to multiple sellers, so readers can buy from the shop they prefer. It is a suggestion, not a rule, so this tool marks a single seller as something to improve rather than a fault.
Do I have to say I got the product free?
In India, yes. ASCI counts free products, discounts, gifts and commissions as a material connection that must be disclosed even if your review is fair, upfront where people will not miss it, not only at the end. The Department of Consumer Affairs asks for disclosures that are clear, prominent and hard to miss.
