Have you already got this: (found on Yelp, Google, Bing, and many questionable y... rating sites)
The only guaranteed way to get rid of poor online yelps, pluses, reviews and ratings is to follow these simple steps:
1. Change your business name
2. Change the owner's name
3. Change your business address
4. Change your business website, email address and telephone number
5. Ask your friends to post as many (fake) good reviews as they can (as seen on Amazon and Yelp - that's why other people do not trust to all-good and all-bad reviews)
It works in all cases!
Choose wisely if you want a rated listing for your new business.
Google advertising may help. For a few 000s you can place your listing above most rating sites. Google loves their ads and advertised sites.
Peter, Google advertising works only for big online stores. You can't compete with them. Also, more and more people who do not like Google use Bing searches. Facebook ads are better if you target new mums and teens. Linkedin ads are better if you target disgruntled employees and job seekers. Simply, people do not click on Google or any other ads anymore. Ad blockers are downloaded more frequently than any other software. You may have much better run for your money if you pay your local printing company to deliver some cheap flyers to houses around your business.
