First of all, consider the possibility that your resume might not be as strong as you think it is. The standards for what a good resume is change over time, so a strong resume from 10 years ago may not stand up nearly as well today. Research how you can improve your resume, as well as reviewing resume samples to see a current, applicable resume.
If you are certain that your resume is well-written and appealing to modern employers, your mistake may be sending identical resumes to every opening. As strong as your resume is, it cannot appeal to every unique hiring manager universally. Look at the job description and the company and think about what aspects they may value that another employer may not. Making small changes to your resume for each new opening is one of the most effective strategies. Even just including a few keywords from the job description makes a big difference.
