I built a custom tool in C# that I am looking to see what type of demand for this tool would be. The tool is built around the ability to send out manual links requests and directory submissions at an unprecedented pace. I sent out 250 manual link requests and 200 directory submissions in about 6 hours earlier today. I got 4 links so far from this. My experience is usually you get 1/2 the requested links in the first 24 hours. Here is what the tool does so far (I keep adding stuff and fixing bugs as i find them) You can easily setup emails to be sent via your email client You can import a list of websites (I usually load up websites my competitors have links on to see if I can get a link too) and mark the status of each website (link request sent, website doesn't work, got a link, spam, etc) You can import your competitors websites, and while viewing a website, your competitors links will be outlined and highlighted. Next to their link, you are shown the exact url the link points to and the follow/nofollow status. Every time you navigate to a page, any email address found on the site is loaded into a listview. Double clicking the email address in the listview will send that email a link request (You can custom setup the email to say whatever you want, including variants). If the website uses a contact form only, clicking in the input fields will popup a list of items you define (for example, you click in the 'Name' field, your options popup, you select 'Name' from the popup list, and whatever value you have assigned to 'Name' will appear in the text box.) Directory submission pages learns as you do them (meaning if it sees an input field you've encountered before, it knows what to fill it in with the next time it sees it). I's say after 15 directories, my app had seen just about all variations that existed, and submitting a directory is as easy as clicking a button (you have to type in the captcha) Custom logging keeps track of emails you've sent, so you can mark their status at a later time if need be. This program has been a lifesaver for me, I can go to a site and have a link request sent out within a minute without all the hassle of opening up Outlook and copy/pasting all kinds of crap around. Would this tool be something many people would buy? Or are their other services out there that do that same thing but better? What other features would make this application stand out (Don't hold back, I can build ANYTHING into this application without much effort) If people are interested, I'll post screen shots.
