Washington - You might want to think twice about making reservations at that restaurant with only five-star raves. And that hotel with all those one-star pans may very well be fine. The reason? Many of the reviews you're reading may be fictitious.

It's difficult to obtain reliable figures on what percentage of online reviews are fake, but research by academic and industry institutions, including the University of Illinois at Chicago and Best SEO Companies, a search engine optimisation business, puts the figure at between 20 and 40 percent overall. According to an investigation by Which?, a UK consumer advice website, almost half of the five-star reviews for two of the top-10 hotels in Last Vegas were questionable.

Online reviews can make or break a business, and a bustling "review farm" industry has sprung up to write glowing recommendations for pay. You need only type "buy reviews" into Google to have your choice of vendors. Industry efforts to weed them out are ongoing: Amazon has an ongoing lawsuit against 1,114 Fiverr gig workers who offered to write fake reviews. And last year the Federal Trade Commission brought its first suit against a review farm.

A Pew Research Center study found that 40 percent of people "always" or "almost always" check online reviews before making new purchases, while 82 percent do so at least "sometimes." Consider that against the Harvard Business School study that found that a one-star increase in a Yelp rating leads to a 5 to 9 percent increase in revenue. You can see why restaurants, hotels, bars and attractions are tempted to buy reviews.

Fortunately, there are tools and strategies savvy travellers can use to spot the phonies.

Here are some of them:

Star ratings aren't a great indicator

"What does a five-star review mean?" said Saoud Khalifah, the founder of Fakespot.com, a tech firm whose software helps identify rigged reviews. "If the food is five-star but the waiter is one-star, how do you score your review?"

There is some value in stars, though. The more reviews there are, the more likely it is that the star rating will have some validity. It's much harder (and more expensive) to manipulate the star ratings when there are more reviewers. "If there are 10 to 20 reviews, I would be pretty sceptical of the star rating," said Myles Anderson, the founder of BrightLocal, a marketing firm that helps companies manage their online reputations. "If it's got 2,000 reviews, it's much harder to influence," he said. Reviews that award between two and four stars are less likely to be screeds or fakes. A study by professors at Northwestern's Kellogg School of Management and the MIT Sloan School of Management found that reviewers who probably bought a product were only half as likely to leave a one-star review as unverified buyers.

"Look for the middle of the pack," said Andy Beal, CEO of Reputation Refinery, a reputation consulting firm. "I tend not to focus on the one- and five-star reviews. Competitors with ill intentions are going to leave one star. If it's a friend or an affiliate, they are going to leave a five-star."

If the site breaks out the quantity of ratings behind each star, as Amazon does, look for a pattern. Are there many more threes than fours?

Also, look for patterns in the details of reviews. Are there numerous complaints about thin walls and lumpy beds? "There is no smoke without fire," Anderson said.

Details provide a clue to authenticity

Studies by a team at Cornell University found that truthful reviews use words specific to a hotel experience, like "price" and "check-in." Fake ones use more generic words like "vacation," "family" and "experience" accompanied by a lot of commas and exclamation marks. Fake reviews are also likely to include more superfluous scene-setting, as in, "My husband surprised me with a lovely anniversary weekend trip ..."

You should also be suspicious, Khalifah said, "if reviews are all 100 percent, and they are all one line long - that's not how anyone writes reviews."

Uniformly high ratings alone might be a red flag. "We all know nothing is ever picture-perfect," Khalifah said.

Hired reviewers cut corners

That gives you an advantage. "They are often pretty lazy about the reviews they write," Anderson said. Look for "limited text, or identical reviews on two or three sites." Anderson suggests that you cut and paste a segment of a review into Google it to see if it shows up elsewhere.

Also, look up the reviewer to see what else they have written. "If you find someone who has written reviews of 50 different Chicago hotels ..." Anderson said. "People don't stay in that many hotels in one city."

And so do their employers

Look at the time stamp on reviews. "If a business has 200 reviews and 100 came in one month, they were likely purchased," Anderson said. Businesses tend to buy in bunches, he said. "Then the budget runs out."

Another hint is if the posts are timed just before heavy travel dates, when hotels and restaurants know people are most likely to be shopping. "We notice a bump in fake reviews right before any travel season," Khalifah said.

Look closely at photos

A photo does a great deal to improve trustworthiness of a post. "Images are really important," Beal said. "If a review includes images of the property or the food it greatly improves the credibility of the review."

But the fakers know that, too, and for an extra fee will include photos. One easy-to-spot tell is that bogus reviewers often use a celebrity photo as their avatar. A simple way to double-check the legitimacy of a photo is to do a Google image search, which can reveal whether it was snatched from another site. If there are duplicates, beware.

Take business responses into account

Just as important as the comments are the responses from the businesses. "It's a really big plus for any property that is actually responding," Beal said. "Then you want to look at what the response is."

"A lot of businesses come out fighting," Anderson said. "It's quite a good rule of thumb to steer clear of the businesses that are pugnacious." Conversely, he said, no business is perfect, and a conciliatory response "can cover a multitude of things they get wrong."

Diversify your search

It may seem obvious, but don't do all of your searchings on a single site. "My first advice is research as much as possible from as many sources as possible," Khalifah said. Not just the big travel and booking websites, but vlogs, blogs, Google, Yelp and vacation videos. "That gives you a much better picture."

A word of caution: Some sites share information, and many are owned by a single company. For instance, the Expedia group owns not only Expedia but also Orbitz, Hotels.com, Trivago and others.
