Google Inc, owner of the most popular Internet search engine, unveiled a tool that will let users block unwanted websites as the company aims to improve the quality of its search results.

Users can click on a link in query results that gives them the option to hide all listings from sites that they dislike or find offensive or of low quality, Google said in a blog post. Once an Internet domain is blocked, the user will no longer see those results in future searches, the company said.

Google, which gets most of its sales from search-engine advertising, is trying to refine the relevance of its results after receiving complaints that spammers and some websites game its system to get more prominent placement. Google last month said it changed the way it carries out Web searches to feature more "high-quality" sites, affecting 12 per cent of queries.
