what about safety in your opinion? actually i could more or less agree with guys above that it could be computed by Google
Every approach to Link building grey/blackhat could be computed. Guest Posting is Grey/Blackhat approach of building links, Matt speaks often against it but that doesn't stop webmasters from outreaching and getting links through that process.
Niche edit the other way round is still one of the best ways to acquire links that sounds and look natural if done right.
Take for example ;
I found a page of my website ranking for LT keywords I'm not quite targeting. I take that as an opportunity to target those keywords by writing more contentsa,updating the oldcold on the page.
Updating your website content with more information is what Google likes (more the merrier).
Google wants you link to external sources (resourceful page). Writing more content I can decide to outbound to page I found resourceful.
It would make no sense targeting a page that's not closely related to your niche.
Moreover, I found a prefferd approach since ;
1. It gives optimal results when done right (Everyone is after results)
2. Referral traffic to your target website.
3. Most aged pages have Ref domains linked , you most likely won't need Tier links boost the page authority.
Not all websites accept Niche edits which makes guest posting a major alternative.
