Yesterday, I had seen thread at Google Webmaster Help. Over there one webmaster users asking that if a pretty large number of broken backlinks that are got internally so, there is anynegative impact on Google SERP or ranking.
The reply is it won’t inevitably injure the entire site’s ranking in Google but it does hurt your internal link structure and hurts the user experience on your site or blog. But usually, the invalid URLs do not hurt the site's ranking on an entirely. It does injury the particular invalid page from Google ranking – since it’s invalid. It doesn't give you the total pros of utilizing your internal linking the most favorable way.
