How Trustworthy Is This Tool

Hi guys.

I am trying to get my house in order (well, my site actually).

I found an online tool called onpage . org and it seems pretty cool with lots of info and advice on what to change. But do any Pro's out there know how good its advice is and weather I should follow up on what it suggests? The reason I ask is that a lot of it seems over my head. So I was hoping I could sub the work out and give somebody the login details for OnPage and then set them up a sub account to access my site to make all the corrections.

Any advice appreciated.
Thanks.

Onpage optimisation is only a small part of what ranks you, outside of the relevance and quality of your content.

I would just implement the "biggies" and focus on content and links.

The biggies are things like slow page load times due to various CSS and other files which it says to merge into one blah blah. Things I know nothing about. Does anybody in here who knows what they are doing fancy a little project?

Just follow your heart, usually your instinct will help you know which programs are legit or not

Take everything you read with a grain of salt. Intuition is always a good thing to follow. If it feels right, it generally is.
