LINK BUILDING · SEO GLOSSARY
Link Neighbourhood
The broader context of sites that link to the same pages you link to — or that are linked to by the same sites that link to you — used by Google to assess whether your link profile is associated with high-quality editorial sources or low-quality link spam networks.
Definition
Link neighbourhood (or link neighbourhood analysis) refers to the broader web graph context surrounding a page or domain: which sites link to the same destinations you link to (your outbound neighbourhood), and which sites are linked to by the same sources that link to you (your inbound neighbourhood). Google\'s link graph analysis considers not just individual links but the interconnected network of sites that form a link neighbourhood. A high-quality link neighbourhood: your page links to authoritative sources (academic, government, respected industry publishers); your page receives links from sites that also link to authoritative sources; your link profile does not overlap significantly with known link farm networks or spammy blog networks. A problematic link neighbourhood: your page links to link farms or content networks known for selling links; you receive links from sites that primarily link to other sites in link schemes; your backlink profile overlaps heavily with sites known to use paid link networks. The link neighbourhood concept explains why receiving a link from a site that is part of a link scheme is risky even if that site appears legitimate in isolation: the neighbourhood signals (what else does this site link to, who else links to this site) reveal the scheme. Google\'s systems can identify neighbourhoods of sites that primarily exist to manipulate rankings through reciprocal or paid linking.
Why it matters for SEO
Link neighbourhood analysis is why link quality evaluation goes beyond individual link metrics. A site with "high domain authority" that primarily exists to sell links to anyone who pays has a problematic link neighbourhood — even if its authority score looks good in third-party tools, the pattern of what it links to and what links to it reveals the scheme. Accepting links from such sites contaminates your own link neighbourhood. Disavowing links from known link scheme participants is part of maintaining a clean link neighbourhood.
How DeepSEOAnalysis checks this
DeepSEOAnalysis checks outbound link destinations on the audited page — identifying whether outbound links go to authoritative, relevant sources (positive neighbourhood signal) or to known low-quality link pattern sites. The audit flags outbound links to sites with suspicious patterns. For inbound link neighbourhood analysis (which sites link to you and what they link to), a backlink database tool with spam score metrics (Ahrefs, Moz Spam Score, Majestic Trust Flow) is required.
