SEO For E-Commerce Site

Any business website is always designed especially for promotion of specific products or services. If this business website is also an ecommerce site, it means that it is one step forward in a strategy towards business promotion. 
E-commerce Site provides a strong interaction with customers directly and offers them online way to purchase products or hire services. It has an edge over non-ecommerce business sites in getting revenue without spending time for that. Your e-commerce site is selling your products or services 24 hours a day and 7 days a week and even during business hours your customers don’t need to call you. There is no need to hire sales staff; your site is itself your sales representative if it provides all of information to the visitors of your site about your business. 
Despite this big importance of ecommerce site for any business, it has one drawback also. It is regarding ranking in search engine listings. Very few of ecommerce sites are indexed by spiders and fail to get high rankings in listings. On the other hand any non-ecommerce business site may fail to get big revenue but it will be placed in top ten placements and your beautifully designed e-commerce will not be found in even five pages. The result is clear that non-ecommerce site may not increase sales online but will be successful in conveying their message to their customers. The only thing which makes a difference is shopping cart.
Miva Merchant and OS commerce are renowned shopping cart systems being used by many e-commerce sites today. These systems are not designed for optimization point of view and are having low capacity to create pages. That’s why search engine spiders don’t get them in their listings. You will see that some of e-commerce sites having these shopping cart systems are listed by search engines spiders at high ranks; it is only because of 3rd party ad-ons provided to them.
Now you would ask what we should do now to solve this problem. You are having two options to pick from. One is to create a front-end page separate from your shopping cart. This will enable you to create more pages and search engine spiders will get on them. It seems to be good option but it has one negative aspect and that is it will remain restricted to a limited size of front-end size. This only thing moves us to pick second option and that is to find a search engine friendly shopping cart for your e-commerce site. It is a difficult task to do. There are many things which should be considered while making selection. You need to see some other factors also like customization capacity to your pages, its easy features to add products, making changes in your pages and most important thing is spiderablitiy of web pages it can provide. 
After making good selection you would be able to add hundred of pages to your site. It will be an expensive choice but it will also save your money to spent on development of front-end page also and compensate and benefit you later by generating substantial revenue.
