Another term for inbound links is “backlinks”.

Are backlinks good for SEO?

Backlinks are very important because they are supposed to be a measure of the popularity of your site among the Web audience. It is necessary to say that not all backlinks are equal. There are good and bad backlinks. Good backlinks are from reputable places - preferably from sites with a similar theme. These links do boost search engine ranking. Bad backlinks come from suspicious places – like link farms – and are something to be avoided. Well, if you are backlinked without your knowledge and consent, maybe you should drop the Webmaster a line, asking him or her to remove the backlink. [ according to webconfs.com]
