I have been working for a particular web design and internet marketing agency; and for our own website and for many of our clients I have been handling the SEO part. In order to help me manage my work and time, my boss has planned to help me by getting me SEO software. He has been Considering Web CEO, IBP, SEO Elite and SEO Powersuite tools. Has anyone ever worked with these tools? Are they any good in the first place? I am a little confused as along with great reviews I have also heard some warnings on their work and functioning.
