>How many ways can a site talk about a Canon Rebel Digital Camera?
At least three:
(1) The product specifications. Canon has these, and there's no point in listening to anyone else on the subject. On the web, any honest person will link to Canon's website for this information, and anyone who doesn't, ought not to be considered honest.
(2) Promotional material -- "the buy, buy, buy today!" chorus extended to any length, and with any elaboration. This is generally practiced in the retail business, but has even less claim to be listed than plagiarized product descriptions. The presence of this non-information on the website of a genuine retail establishment, won't necessarily keep a site from being listed, but at best it weighs on the unfavorable side of the balance. The editor should ignore this (if it can be done without too much inconvenience) and look at the actual unique content on the site -- that is, the uniquely authoritative information about the unique services offered by the retailer. But for surfer's purposes, the marketing garbage could just as well be left off, and the website would be more useful. Genuine honest retailers know this -- look at a newspaper, at the 4-Day Tire Store's ad: it consists of terms of service (i.e show up at THIS location on one of THESE days and get THIS tire for THIS price--go somewhere else to see the specs on that tire!), or a serious Camera retailer in the back of a major photography magazine. And a Kroger's grocery ad doesn't give the nutritional specifications of canned Jolly Green Giant Spring Peas--just the price and store location.
(3) Product reviews: the result of a uniquely experienced and knowledgeable reviewer, sharing his unique personal insights into the relative value of products that he's in the habit of using, with no ulterior marketing motive: such as zdnet testing labs, and the like. There can be as many such websites listed as there are persons (or groups) with the unique skills to use and test products, and distinguish the result: which is, for most products, a relatively small group.
A lot of spammers try to emulate these experts as ODP editor bait, to create "doorway pages" on which they can include their toxic marketroid content. I reviewed one article about a SUV by a "car reviewer" who had obviously never sat in the cab. He waxed eloquent about the fact that it was big and obviously had low gas mileage: mentioning each of those inanities several times without even providing the quantitative detail he could have copied off of the vehicle's price sticker. By dint of persistent belaboring the obvious, he eked out a several-hundred-word "artikul" that, in his opinion, merited a deeplink in the ODP category about that brand of vehicle. Another "travel portal" waxed eloquent about all the things that a traveller could find in <name of major city omitted> -- the only attractions the reviewer actually NAMED in his enthusiastic civic boosting were -- a major league sports stadium, and shopping. (I suppose the ignoramus of a webmaster watched whateverball on weekends, and that was all he knew.) Well, that kind of inanity characterizes most of the so-called "consumer information" sites, because that's the level of ignorance characterized by most free-lance mercenary search engine result hijackers. And yeah, they don't KNOW anything unique to write about their products. But just because a thousand ignoramuses babble about some subject just because they want click-throughs, doesn't mean there aren't genuine experts who know about imaging distortions, car maintenance costs, or local culture. Thing is, you can pretty well count on the genuine subject experts to NOT show up in the regular SEO forum circuit: and even in a non-SEO forum like this, the genuine subject experts mostly appear (if at all) incognito, in a editor's robe and tonsure.
