Product listing ads are basically websites that online vendors, such as Renogy, use to advertise their products that are for sale on an external webpage. Websites that are specifically for product listing ads allow visitors (potential customers) to instantly compare prices on several different versions/brands of the same product. This is greatly advantageous for online sellers that have many big ticket items, such as home improvement products, tools, jewelry, or even expensive electronics. As a seller of solar panels, product listing ads help Renogy generate sales from a larger pool of customers. Right now, a potential customer can instantly compare prices of Renogy vs. Competitor products on Google Shopping, Yahoo! Shopping, Pricegrabber, Become, Pronto, Shopzilla, Bizrate, Amazon Ads and many more. So if you have your doubts that Renogy is not competitively priced, we would like you to see for yourself. Check us out on one of these sites!
