Hi Martin,
First of all, as mentioned previously, you need to spend time ensuring that your tracking software (Google Analytic's or equivalent) is set up correctly in order to accurately track, eCommerce/revenue as well as any other important goal conversions such as contact forms, enquiry forms and CTA's. Having this data tracked precisely will open up a whole world of data that you can use to identify, problems relating to how the website is designed, structured and optimised which will help you and your client in terms of improving user experience and CRO.
Get your products listed in Google Shopping.
In terms of optimisation of your products a lot of people will tell you to focus on product descriptions, copy between 250 - 500 words ect. I'd advise you to focus on creating a strong listing so as to create the best user experience:
- Clear product and page titles
- Compelling Meta Descriptions
- Clear pricing
- Strong and appealing images and videos
- Bold CTA's "Order Now", "Add to Cart", "Buy"
- Focused descriptions that highlight the products USP's/attraction and specifications (use short text and bullet points as these are easier for users to quickly scan and absorb than lengthy descriptions.)
- Visible social share options with CTA's ("Have a friend that may be interested in these jeans?" or "Show off your new jeans with friends") - let your customers help with the marketing!
Push for customer reviews and ratings.
As mentioned there are many many more things to focus on, an ecommerce site is an ever growing thing and new problems and challenges occur frequently, therefore my top tip is to monitor analytics and site performance like a hawk!
Hoep thsi helps get you started!
