The campaign involves an advert that will allow people to contact the incident room via the social networking site rather than calling in.
Police said Facebook was more effective than posters and leaflet drops.
Detectives investigating the murder of the 25-year-old landscape architect have said there was no evidence she was sexually assaulted, but they have not ruled out a sexual motive.
The force has appealed for sightings of a 4x4 seen near to where her body was found.

Her landlord, Chris Jefferies, 65, who was arrested on suspicion of her murder, is free on bail.
Det Ch Insp Phil Jones, of Avon and Somerset Police, said he hoped the Facebook appeal would encourage more people to come forward with information.
The force has already received 260 messages through the website "The majority of people these days are spending time on Facebook and other social networking sites; this has become part of everyday routine for many people," he said.
"This advert allows us to point people to special features on our website with all the latest information, it allows them to contact the incident room direct online rather than calling in.
"I would once again urge anyone who may have not contacted my team and may have information that could help this enquiry to contact us. Let us decide if this information is significant."
He said police had successfully used Facebook in a number of high-profile cases because information could be shared more widely than by poster.
Scott Fulton, head of e-services at the force, said: "On this inquiry alone we have had shares of the story from the force's Facebook page of 24,220.
"Additionally there have been over 63,000 views of the news updates on our website, a further 18,000 on the dedicated Jo page and over 70,000 views of the CCTV clips on our YouTube channel.

Crime scene investigators are continuing to examine Miss Yeates' flat in Canynge Road.
There was a sign outside the building saying "Do not enter, dangerous chemicals" and officers wearing white suits came out of the flat wearing masks.
A number of uniformed officers were also seen entering Mr Jefferies' flat on the opposite side of the building.
Miss Yeates was last seen at about 2000 GMT on 17 December after she had been drinking with colleagues in the Bristol Ram pub in Park Street in the city.
She visited three shops on the way home and was filmed on CCTV.
She bought a pizza in one of the stores - the receipt was discovered in her flat but no evidence of the pizza or the packaging has been found.

Facebook faces challenges in reaching one billion users, not least because Europe and North America will soon reach Facebook saturation, and markets such as China and Russia are dominated by domestic rivals. But the developing world is a huge opportunity for Facebook and one it has already begun to address by working with at least 50 local operators to offer Facebook Zero, a pared-down version of the site that users can access for free via mobiles.
Already the web's biggest photo site, Facebook has disrupted sites such as Photobucket and Yahoo-owned Flickr. Facebook has provided a vast platform that allowed games studios Zynga and Playfish to flourish; Zynga's revenues alone are estimated at $600m for 2010.
Television is lined up next; Facebook is an important app being built into many internet-connected TVs from Samsung's Smart TV to Yahoo's Connected TV that will allow users to Facebook message friends about the shows they are watching together, finally giving TV the potential for targeted advertising.
The volume of information generated by Facebook globally is daunting. In any 20 minutes, Facebook typically sees 1m shared links, 2.7m photos uploaded and 10.2m comments.
