just few days ago i start my own online eCommerce business.I launch a website.I read few article where most of the SEO experts give there opinion.Most of themes are try to say that after penguin update and also panda update ,on page SEO is so important.To Get 1st page on Google ,every web site has need good quality and also unique content. Most of SEO experts are say that every content must have at least 300 word. But my question is that my website is product selling website.In here really very difficult to write 300 article for every product details. so can i maintain my on page SEO? and also i want to know ,suppose i write a product details which carry 100 word. That means my article has 100 word which is not google friendly.Now if few customer write their review about that product after buying .which may be carry 200-300 word. Now in that time google is count my article as 100 word or 300-400 word? i expect lot of comment from all SEO expert.
basically On page factors differ from general website and ecommerce website.. so you should keep users in mind while developing website, User interface is more important than On page.
If you are planning to do an On Page SEO for a Ecommerce website then you should concentrate on creating better navigation through building perfect categories. Category pages play a vital role in a Ecommerce website. As you will be posting same products in multiple categories then make sure which category page should be recognized by google for indexing. In this case you can use canonical tags to tell google about the duplication. Pagination also plays vital role wherein your multiple pages of the category page is indexed by google. Learn about pagination by searching online. Try to create unique product description with relevant keywords of the products in the Product Title. This should be reflected in the meta title tag, meta description, meta keywords, H1 tag. Try to use "Microdata or Microformats".

100 words content on the product page doesn't makes any sense.., you elaborate it with some useful content having specifications, advantages, disadvantages and some reviews which were given by past users of the product (if you get).. atleast try to make have 250-350 words.., suppose for a scenario if no product is purchased or else purchased, what if the user is not interested to write a review.. so your product page is still only 100 words which is not a search engine friendly (reviewing product is not in your hands, but writing about product info is all what you got).. my advice is not to depend on a customer of writing review on your product.., rather you keep your product description at around 250-300 words which is not a spamy one.., hope this clarifies your 2nd question.. let me know if you still have any questions on this..
