Any reputable SEO company would never use these types of tactics, but still the problem exists.
Some of the most common Negative SEO techniques include:
- Buying links and pointing them to a competitor’s site in an effort to negatively affect their search engine rankings.
- Website Hacking to affect a site’s organic SEO strategies.
- Reporting a competitors black hat SEO efforts.
- Review bombing by listing lots of five star reviews on a competitor’s site making it seem like they paid for fake reviews.
- Build strong domain authority and popularity for your site which will make it less likely that it can be negatively effected.
- Regularly review your site metrics and identify any major changes as they occur.
- If you are affected by paid links that you haven’t actually purchased, but you rectify things quickly it’s likely Google will not hold you accountable.
- Stay on top of feedback about your site using Google Alerts and if you think there have been any reviews generated improperly or a lot posted in a short space of time, make sure you report the problem with the site owner.
- Keep sitemaps current and make sure they are linked to your Webmaster Tools accounts so that new content is regularly spidered.
- Use rel=canonical tags to secure the authorship for your content and reduce the likelihood of duplicate content issues removing your snippets from search results.
- Monitor any unnatural links that appear suddenly. Google’s Webmaster Tools makes this easy and you can quickly identify spammy links. You can then use the Disavow tool to remove the importance of these links to your backlink profile. If there is still a problem, contact Google to help you get back on track.
