So to make sure I get the title I want I need to put the text on the page in a prominent location, then make sure I have plenty of links with that text? Simple
As soon as they make the displayed title based (even in part) on an off-page factor (external links), they are forcing people to take control of that off-page factor to be in control of their own title in the SERPs, and people will, because it's IMPORTANT.
They really make their own job harder than it needs to be with some of the 'neat' things they do.
ADDED: Really think about it for a minute ... They're taking control of our title in the SERPs. Eventually we'll figure out what it's based on and take control bask ... All they're doing is making more work for everyone.
They work to change the title; we work to change it back.
end result = extra work for all of us, to keep the title in the SERPs the same as it is on the page. ShakeMyHead!
Yeah, there's some who won't do it or won't know, but those of us who do this for a living will just game the title changing system to get the title we want, and what good is a title re-writing system if we're in control of the factors they're using to rewrite the title, which we will take control of if we have to ... Huge thanks to the G engineers for doing a bunch of work to create some extra work for us site owners.
