In the search engine sector, topic relevance is mainly used in connection with backlinks ("incoming links").

Topic-relevant websites are websites with similar content. Backlinks from websites with similar topics influence a good position in the search result more strongly than backlinks from non-topic websites. Search engines assume that links relevant to the topic will be inserted in order to offer visitors further, helpful information. For non-topic backlinks, the probability is higher that they were purchased or inserted exclusively with the aim of improving the position in the search result.
