Deck builders who are enrolled in MoistureShield’s MVP preferred contractor program can now take advantage of the company’s new partnership with the online consumer review site Angie’s List . Certified MVP contractors will be able to work with a dedicated Angie’s List coordinator to set up and fine-tune their company profile, and learn how to ‘enhance their e-commerce presence’ on the popular site, according to a recent company press release. They’ll also receive a small discount on advertising.

But subscription-based Angie’s List and free competitors like Yelp and home services newcomers and Porch have been getting mixed reviews lately. In a recent high-profile case, a contractor sued a former client for posting negative online reviews on Yelp and on Angie’s List. Other challenges to the usefulness of these sites include attempts by both consumers and businesses to game the system by posting fake reviews, and charges that advertisers get preferential treatment.

Despite these flaws, plenty of contractors have had good success with Angie's List and other online review sites. Still, if you're unfamiliar with some of the pitfalls, it may pay to do a little research before expanding your presence on any of these sites, since you'll be putting your business reputation on the line.
