"Auto-Rewards"  pay Gift Points to readers whenever they submit a review for an item you've set up an auto-reward for. Under the Community menu on the left-side navigation panel, there's even a separate director of Auto-Reward Items so those who are looking to earn some Gift Points by reviewing can do so. Auto-Reward items are appealing to reviewers because you're compensating them for their time.

"Review Requests"  similarly allow you to offer Gift Points in exchange for reviews, but to specific members who have enabled Review Requests on their account. If you don't like the idea of just anybody offering you feedback and shelling out GPs for it, you can make requests of specific reviewers that you respect or admire and offer to pay them specifically to review your work.

"BidClick System: Sponsored Items, Links & Genres"  allows you to sponsor your items and have them listed higher up in a particular genre or item type listing. For example, if you've written a horror story, you can bid to have your item show up on the first page of the results when someone goes to Browse By Genre > Horror, by paying for the clicks that you get for having a sponsored item high in the listings.

Purchasing Prizes and Services offered in fundraiser activities can be a great way to get feedback as well. Auctions and Raffles are the most common types of fundraisers on the site (other than direct fundraising by specific activities), and many Auctions and Raffles will offer prize packages that include reviews and similar. Some members even have stores or groups where you can purchase reviews from an actively reviewing group. If you have some funds to spend and want to help contribute to a good cause, purchasing feedback from those offering it in the form of a package or services you can buy can be a great way to ensure you get feedback.

Reciprocal Reviews are when you offer to read and review someone else's work in exchange for them doing the same for you. This often works really well with other members who are having a hard time getting feedback on their work; you can help each other by reviewing one another.

Being Active on WdC may sound like simple advice, but it really is one of the best ways to get engagement for your stuff. If you're just on the site asking other people to do things for you (e.g., review your work, participate in your activity, etc.) without maintaining a presence in the larger community, it can be really hard to find people who aren't going to eventually feel used or put-off by all the requests. But if you participate in other peoples' activities, offer feedback to others, and engage other members where they're at, you can build genuine relationships where you want to help each other. Some of the closest relationships I have on the site are with people for whom I was willing to participate in their activities and offer feedback on their work before I ever asked them to help me out with mine.

Advertise your work on any of the public forums where you're encouraged to do so. Under the Community menu on the left-side of your screen, there are bulletin boards where you can post to advertise your contests, activities, blog, or even a Shameless Plug Page where you can post anything you want. There are members who spend a considerable amount of time looking through these listings for things to read or ways they can participate in the site. It may not be guaranteed engagement, but it's a way to get your items noticed outside of your port.
