So a link to you from a page that’s also linking to all kinds of other pages isn’t as valuable.
When another website links to one of your pages, it’s a vote of confidence. It’s an indication of relevance , and Google notices.When many sites link to one of your web pages, even better. Link popularity works like any popularity contest. You want a lot of votes.The best links are from sites that have a high link popularity themselves. These links are worth more. Just like a popularity contest, one vote from someone popular is worth more than a dozen votes from the unknown.If a page is linking to several sites, the value of those links is divided. So a link to you from a page that’s also linking to all kinds of other pages isn’t as valuable.
