If you do any article marketing you know how time consuming it can be. Not so much the writing itself, the biggest problem is submitting your articles to all the different directories that are online. Now you could just submitted to one directory but if your serious about your income then would be be using as many directories as possible and to do that you need software.
There are many article marketing software programs out there that will spin your articles and submit them to directories for you but not all of them all equal. Some are old and outdated and only submit to the top 5 directories, and thats not good because there are hundreds of article directories online.
Also many of them do not have great support after you purchase them. many times you are on your own and have to figure how how to use the software with no instructions or anything. Your software should come with updates for life and always offer support.
It should also be easy to use with push button results. If you have to spin an article just push a button and it should be done. If you want to create multiple accounts for multiple directories just push a button and it should be done. If you want to submit your article to over 100 of those directories just push a button and it should be done.
These are just a few things I know about article marketing software and I hope they help you.
