Hi JBNorthAM,
In terms of SEO for on-page tagging, you can approach it a number of ways, but we like to take a simple approach on this. Do your keyword research if you wish to target a keyword on those given pages and then get creative. *Remember, to also hit your Meta Description as well for this and make sure that if you do target a keyword in the Title, that it is referenced in the page content itself like H tags, paragraph text, alt image tag, hyperlink to another page or blog article or website, etc...
Not sure what industry you are talking about, but let's take a Web Design company in a City for example. You could try this:
- About Us = About Our City Web Design Firm | Company Name
- Investor Relations (not sure you'd optimize this page, but could be) = Investor Relations Info for Our Web Design Company
- Careers = City Web Design Career Opportunities | Company Name
- News & Events = City Web Design News & Events | Company Name
Again, these are just ideas yet something to consider as there are a number of strategies to rework and make them more interesting for the searchers seeing the Title in the SERPs. Make them attractive, creative, meaningful and it should help get their attention and, ultimately, their click.
Hope this was helpful! - Patrick
