There are some large ecommerce websites which spend a lot of money on PPC advertising. But if you try to order anything from the website, atleast 50% of the time, you will get some error during the checkout process and are returned to the home page.
It is both a waste of the buyer’s time and the ecommerce websites money.
Most web hosting companies include a free shopping cart software for Ecommerce . For some web hosts there is a script which installs the software on the website. The shopping cart software allows the visitor to select a particular item and add it to the list of products he wishes to purchase.
The web designer can create a standard web page and integrate the shopping cart by adding the relevant code to the web page, so that the check out and payment pages look similar to the rest of the website.
