It's easy, and on Criags List it's free.  You will make some extra money, declutter your home and help someone out that wants what you have. Plus it's great for our environment because you are recycling your unwanted items by making them available to someone who can put them to use.

6 tips to make it easy:

#1 -- Your title is critical.  You must have as many keywords in it as possible (or no one will find your listing) and use all of the characters they allow you.  For example, if you are selling kid size hangers you may use this as your title:

Kid size white plastic hangers, for toddler & kid clothing

At the bottom of your ad include a line of keywords and put common misspellings of your keywords.  For example, if you are selling an armoire, your keyword line may look like this:
 

Keywords: armore, armour, armoires, TV cabinet, office armoire, media armoire, free standing cabinet

By doing this, your ad will come up on more searches.  Think about all of the words someone may search for when looking for the type of item you are selling.  Include all of those words in your ad in the keyword line at the bottom.

#2 -- Re-post your ad every 3 days.  They get posted in date order and by day 3 it will buried and no one will see it.

#3 -- ALWAYS show a photo.  There are no exceptions to this rule.  People what to see exactly what their getting.

#4 -- Describe your item in depth.  This will save you time from answering questions and you will be more likely to sell your item faster.  If it's a piece of furniture, provide all dimensions, everything you know about the piece (where it is from, when it was made, what it is made out of, what uses it is good for, etc.) and describe all blemishes.  If you don't check your email often, include your phone number in the ad.

#5 -- Start with CraigsList.  Ebay & Webbize cost money to list your items, you need to have a merchant PayPal account and be a little savvy to run a successful auction.  CraigsList is free and easy.  Plus you get to meet new cool local people.  I have friends and clients that I have met through buying and selling on CraigsList.  I have even heard of people meeting their spouses from a sale of an unwanted item.

 
#6 -- Use basic HTML to make your ad easy to read.  To put a space in between your lines of text, put this after the sentence <p>.  To put your text on the next line, put this after the sentence.

With this simple and profitable plan, decluttering your home will be fast, easy and fun!
