Hello, I need to escape Google penalties for duplicate content on a shopping section of my website. The pages are something like "example.com/products.php?price=..." or "example.com/products.php?color=..." .
What is the best SEO solution? Is ok setting up a canonical url for these pages? If that is the case, would be it ok placing inside products.php file something like the following code snippet? [size=4]<HEAD> <LINK REL"CANONICAL" href="http://example.com/product.php?color=red"> </HEAD>[/size]
example.com/products.php?color=red is showing products with color red and with different prices, example.com/products.php?price=100 is showing products with price 100 and with different colors. Obviously I can also have example.com/products.php?color=red&price=100 example.com/products.php?price=100&color=red that are showing the same products for sure. And i have other parameters like "sort" etc... that make pages showing same products.
But the point is, there is high probability that the same products, that means the same content, is also published on many other affiliates sites and of course on the merchant site. My pages publishing products catalog have nearly 0 original content, so probably they differentiate from other affiliate sites publishing same product catalog, only for a different template. Is that duplicate content putting me in danger to get duplicate content penalties?
