I understand on site seo fine, as I have tweeked up my own website a fair bit.

But I am thinking about doing Onsite and Offsite SEO for clients, as I have had a few request now.

So my question is what is the best way to get access to clients websites.

So I can make the required adjustments.

I have one client, who had a company create a website for him, but they have since closed down.
