This is one that I’ve been using for years but realized I haven’t shared it here Most of you will be familiar with _Broken Link Building_ — for those that aren’t, it involves finding pages that were once live, and linked to from other sites, but aren’t anymore. From there, you reach out to the linking sites and request they update the now broken link to your own up-to-date content — well, Wikipedia can be a great starting place for finding broken link opportunities.
Wikipedia itself only uses _nofollow_ links, but it also syndicates links to other sites. That said, if a Wikipedia page is linking to a URL, it’s *highly* likely that other pages are linking to it too (generally higher credibility). Now, one nice feature of Wikipedia is that it highlights if a link is now “dead”. Finding a citation that is marked as “dead” means the link is broken, due to the page no longer existing. Finding one of these means you could build similar content to what it used to have (use Wayback Machine to check this out) and then reach out to any other site that is still linking to it (check out the _live links_ report in Ahrefs).
But how do you find dead links? Simple, use this free tool: https://www.webpagefx.com/seo-tools/wikigrabber/
Enjoy.
Can also do this in Ahrefs.
1. Must enter en.wikipedia.org or prefix on /wiki/ in Site Explorer – https://ahrefs.com/site-explorer/others/v2/broken-links/subdomains/live/all/1/ahrefs_rank_desc?target=en.wikipedia.org
2. Go to outgoing links > broken links
3. Export and filter for your kws in sheets
4. Batch analysis anything that seems relevant
