The right number of backlinks to a website will depend on the industry that you’re in, but there is a general rule of thumb you can use. To rank high on search engines, a website should have 40 to 50 links to its homepage and 0 to 100 links to each individual web page. However, the PageRank scores of those backlinks are important because the higher their value, the fewer links are needed to boost overall rankings. This also depends on the number of competitors’ backlinks that they have pointing to their websites as well.
