Everybody wants to find a good deal on Black Friday, but it can be hard knowing exactly where to turn online.

A quick online search for "Black Friday sites" returns hundreds of sites -- every other one claiming to be the "official" Black Friday deals website.

You could always turn to shopping sites like Amazon.com, which each year offers some of the best online shopping deals, or visit regular deal sites featuring Black Friday sections, like GottaDeal.com, SlickDeals or Fat Wallet.

But the Black Friday-specific deal sites remain your best bet. They offer such things as customized shopping lists, deal alerts, downloadable apps for your phone, and -- the Holy Grail among Black Friday shoppers -- early peeks at store ads.

So, how do you know which sites are the best? Start with our top five top picks and work from there ...

Twitter, tweet, social media

No. 5: Twitter

OK, so we know we said Black Friday-specific sites are the best, but we're willing to make an exception for Twitter.

What makes Twitter perfect for Black Friday is it gives you quick, easy and mobile access to all the best deals. There are tons of Twitter accounts sending out deals in real time, and some stores will even tweet their own sales.

Follow one of those accounts and you can get a jump start on every other holiday shopper.

Finding a feed to follow is as easy as searching for the words "Black Friday," but one of the best and easiest accounts is @BlackFriday. The account, which is also a great source for deals on Cyber Monday, the online deal extravaganza the Monday following Thanksgiving weekend, also offers a shopping blog that offers another way to keep track of deals -- although without the real-time functionality of Twitter.

No. 4: Black-Friday.net

With so many great deals, it can be next to impossible keeping track of every place you want to shop. In the past, you had to scribble down the sales you wanted to hit on a piece of scrap paper and hope you didn't lose it.

Not any more. Sites like Black-Friday.net offer customizable shopping lists that make it so much easier to keep tabs on your favorite deals.

The site also offers e-mail updates whenever a new store ad is posted and also lets you see which merchants are running early sales, which can offer just as good -- or better -- deals than you'll find on Black Friday.

But one of the best features is one that allows you to browse deals by "Popular Products," meaning you won't miss out on an unbelievable deal on that hot toy your child just had to have this year.

The next site on our list calls claims to be your "source" for everything Black Friday ...

BlackFriday

No. 3: BlackFriday.FM

Unlike most sites, BlackFriday.FM shows some restraint in not labeling itself your "official" Black Friday site.

However, it does brand itself "Your Black Friday Source" and manages to back up that claim pretty darn well.

Like Black-Friday.net, you can sign up for e-mail alerts and compile your own shopping list, but what really sets this site apart from the others is how thoroughly it has woven social networking into Black Friday.

BlackFriday.FM was one of the first Black Friday sites to embrace social networking sites like Facebook and Twitter, and it still offers buttons to easily share the deals you find there via those sites.

You'll also find easy links to Black Friday favorites like Wal-Mart and Best Buy, a printable one-page buying guide and all the best Black Friday ads sorted by product categories.
