Hi there,

Submitting to Google Finance has the same requirements for Google News, including unique URL structure (incorporating 3 digits), creating permanent URLs (no overwriting), and that the content is updated every day. You also should submit the site as content for Google News.

If you haven't already, creating a Google News Sitemap is also on the top of the list, which helps Google gain access to news articles a lot more efficiently. Although Google notes that it "does not favor sites that use New Sitemaps", I find it useful simply because it also creates a separate tab in Webmaster Tools, making troubleshooting a lot easier.

I hope this helps point you in the right direction!

Ah, this is a loaded question since the type of client and the range of services can be drastically different. I - like many other professionals - probably take on too much. I have been situations where there was a team of 6 (about half SEO, half paid) with less than 10 clients, but they were big brands. I've worked with dozens and dozens of sites on quarterly retainers with only one other person, but I also have worked alone with less than a dozen clients, and when things got sticky I would outsource for some help. It all depends on how big the site is, how much they are willing to pay for, and how much you want to take on.
