The total number of backlinks and their quality pointing to your complete website result in the overall authority of your domain. The external links that all point to a specific page will help this page to rank in the search engine results (SERPs). The relevance and quality of an external link are very important factors when you like to measure the impact / value of an link. To find out more about quality links have a look at this article on: the Official Google Webmaster Central Blog – https://webmasters.googleblog.com/2010/06/quality-links-to-your-site.html
Hi Andres, sad to know that you’ve not discovered few toxic links using SEMrush. How did you find those toxic links? Have you used any other tool to find them? Also you might want to get in touch with the SEMrush support team and let them know about this issue, so they’ll look into it. But if you still are not comfortable with it, you might want to give a try to Ahrefs for a month or two to really find out the best one among them. I’d suggest you give a try to Ahrefs for some time to see if it’s the right fit for you.
As a long time Moz user and I might even say a super fan of their product, it feels really odd to be writing a review of Ahrefs. But here we go--I love Ahrefs. The design, the UI, the gigantic keyword database and now the newly redesign site audit are a thing of beauty. I continue to be impressed by the data they provide, features that are added frequently and my favorite feature has to be the top pages report. (Not sure why I love that so much--but it just makes it extremely simple to research a site or competitor with that report.)
Ahrefs make use of two link updates in your website - the Fresh Index and the Live Index. Fresh Index which updates at a longer time frame. It shows the dead links on your website, giving you the chance to change or reclaim the dead link. The Live Index, on the other hand, makes link updates every 15-30 minutes. This provides you with the chance to see regular link updates on your website.
