Affiliate marketers need to be able to get credit for everyone who buys through their link, so they must include a tracking code in the URL. Since tracking codes look bad, many affiliate marketers cloak their links through redirects. In that case, the link will look like an internal link to another page on their site which redirects to the tracking link. You may need to disable automatic redirection on your browser to see the full affiliate link.
This may also be a violation of laws in other jurisdictions; ask a lawyer for advice.
Try leaving a comment; chances are the submit button is just an image and isn’t attached to anything except maybe a popup ad.
Look for numbers. Numbers look scientific and serious. Sometimes they are, but only if those numbers actually stand for something that it makes sense to put a number on. What does it mean if one product got a 96% rating in value while another got a 92%. Does the reviewer explain what 96% value means? How much of a discount would be needed to make it a 97% rating? You won’t get an answer because there isn’t one. It’s just made up to impress you by looking important. See if the review contains any actual evidence of having used the product. Ignore ingredient lists, refund policies, etc. ––you can study those yourself without having to buy anything. Ignore star ratings––those were probably just based on the commission payouts. Ignore testimonials––assume those were completely fabricated. Is there anything left that might have come from actual experience with the product?
Copy a sentence or two from the review you are worried about. Paste the text into Google, Bing, Duck Duck Go or another search engine and click Search. If you find the exact text listed on another website, it is likely the review is faked and has been pasted into multiple sites.
