I've gotten lots of email from people who are at the end of their rope, saying that they aren't getting results from posting their resume online. I've discovered that many people who aren't getting results after a long period of time, such as one to five months, have resume flaws that are holding them back. Take your resume to a professional resume writer and get an overhaul. Use the same language employers are using. As you have probably heard, when you put a resume online, most of the time it is searched by database software that picks up key words related to your profession.
Employers look for all sorts of things in a resume, especially the right words.
You can make sure you have the lingo working to your advantage by taking a good look at job ads posted for positions similar to what you want. If you read through about 20 to 50 job ads, you will notice the same words coming up over and over again. Post to the right resume database. Not all resume databases are created equally. The numbers of resumes aren't high, but that is what you want in the case of a very targeted resume database.
