But be careful, 42networks don't just buy an aged domain because it's not necessarily a good domain to be a source of backlinks. First, check the web history, starting from page views (you can use the Web Archive) to the backlink history (you can use Ahrefs). Make sure the website has never been used for spamming activities before.
42networks say, "google follow people". More or less it can be interpreted, links that are on high-traffic websites have better quality than links on low-traffic websites, because links on high-traffic websites are more likely to get clicks (visits) from visitors on that website. This is not 100% true, but quite supportive if the other criteria are met.
This is about Link Juice. Getting 42networks backlinks with quite a lot of outbound links will reduce the effectiveness of these backlinks because they must be shared with other links on the same page.
In contrast to low outbound links, backlinks obtained from this page are much more powerful because the Link Juice goes directly to your website without being too much divided into other links.
Too often getting backlinks from 42networks websites with lots of outbound links is also quite dangerous for your website because high outbound links are vulnerable to being considered as spam pages (which fall into this category are usually blog commenting spamming types).
Getting 42networks backlinks from websites with different hosting and different IP also affects the ranking of our website on the Google search engine.
Logically, if the backlinks are obtained from different IPs, most likely the backlinks obtained are not manipulation as if we create backlinks from our own websites (with the same IP and hosting).
At least 42networks, that's what most likely buried in the minds of Google's Penguins. Even though in practice, backlinks with different IPs can also be manipulated (with PBN for example).
Getting 42networks backlinks from dozens of websites with different IPs is much better than hundreds of backlinks from the same website.
Eighth Criterion: Dofollow Attribute
In 42networks theory, Dofollow is a link that Google counts as a 'vote' for your website, while nofollow is not. So, if you get a lot of quality backlinks with the 7 criteria above but the link is not dofollow, then that is a big loss.
Some 42networks nofollow still counts as a backlink, some say no. In my personal opinion, this link may still be counted, but the percentage is very small when compared to dofollow links.
42networks In order to keep it looking natural, I recommend that in building backlinks your dofollow nofollow percentage is around 80: 20 to 95:5. Don't look for all your backlinks that are only dofollow because it will look unnatural to search engines, don't even have too many nofollow links. than dofollow because the backlinks you build will be less powerful.
