Can you really link two related sites without risking a Google penalty?

How does this statement change the game for site networks?

For years, owners of multiple sites have been navigating the gray area regarding cross-linking. The fear of a manual penalty for link schemes led some to completely avoid interconnections, even when they would have been legitimate.

Google decides: if two sites are owned by the same entity AND share a real thematic consistency, the links are acceptable. The key element lies in the disclosure. Clearly mentioning in the legal notices, footer, or an "About" page that you control both domains is enough to comply with the rules.

This position aligns with Google's longstanding push for transparency regarding sponsored content, affiliations, and now site ownership. The engine does not penalize links between common properties when the intent is clear and the content adds value.

What does Google mean by a "thematically related" link?

Google does not precisely define this term, but real-world experience shows that semantic consistency is key. Two sites on digital marketing can link to each other, even if one deals with SEO and the other with paid advertising.

However, linking a plumbing site to a fashion blog just because you own both will not pass the thematic relevance test. Google assesses whether a user would naturally find it useful to navigate from one site to the other. If the answer is no, the link will be ignored at best, penalizing at worst.

The notion of "high quality" content is not insignificant. Google does not validate links between mediocre sites under the pretext that they are disclosed. The content must remain useful, original, and well-documented, standard quality evaluation criteria since Core Updates.

How can you properly disclose common ownership without harming SEO?

Disclosure does not require a giant disclaimer on the homepage. A simple mention in the footer like "[Site A] and [Site B] belong to XYZ group" fulfills the obligation. Some add a dedicated page "Our sites" listing the entire network.

This transparency does not dilute PageRank nor weaken the authority of the domains. Google treats these links as legitimate editorial references when disclosure is present. The algorithm understands that an ecosystem of sites can exist to cover different segments of the same market.

• Links between affiliated sites to the same company are not considered black hat if disclosed and thematically coherent
• Public disclosure can be done via footer, legal notices, or dedicated page without negative impact on ranking
• Content quality remains a prerequisite: Google does not validate links between mediocre sites even if disclosed
• Thematic consistency is evaluated by relevance for the user, not just by common keywords
• This rule does not cover PBNs (Private Blog Networks) created solely to manipulate ranking without user value

Is this position really new or just a clarification?

Google has already been applying this principle in its manual actions for years. Large companies owning multiple domains (Amazon with Zappos, LVMH with its brands) have never been penalized for their cross-linking. The novelty lies in the public formalization of this tolerance.

What Google does not say: the line between "legitimate site networks" and PBNs remains subjective. An algorithm can hardly distinguish between two sites created to serve different audiences from a network built to manipulate ranking. Disclosure becomes the good faith signal that tips the balance.

What gray areas still exist despite this statement?

Google talks about "high quality" without defining a threshold. Does a site with 20 mediocre articles linking to your main site pass the test? [To be verified] on real cases, but experience shows that Google tolerates sites with a history of regular publication and measurable user engagement.

The issue of link volume is not addressed. Can you place 50 links from one site to another? The logic suggests that a natural linking structure, proportional to the amount of content, remains acceptable. But no official numbers exist. A site with 100 pages systematically pointing to the same sister domain via 80 links will appear suspicious.

Another point not clarified: the link anchor. Do the same diversification rules apply? Probably yes. Consistently using exact match anchors between your sites, even if disclosed, remains a risky practice that could trigger an algorithmic filter.

In which cases does this rule not protect against penalties?

If the site network is used solely to artificially boost ranking without providing distinct value to users, disclosure is not sufficient. Google analyzes intent: sites created post-hoc to push a main domain remain under scrutiny.

Sites with duplicated or spun content among themselves do not benefit from this tolerance. Even if disclosed, domains publishing variations of the same article to link to each other violate the quality guidelines. Disclosure excuses common ownership, not content mediocrity.

What do you need to change specifically on your current sites?

If you own multiple domains that are already linking, start by auditing the disclosure. Add a clear mention of common ownership in the footer of each site or create a "Network" page accessible from the menu. The text can be simple: "[Domain A], [Domain B], and [Domain C] are published by [Your Company]."

Next, check the thematic consistency of existing links. Remove links between sites without obvious relevance to a user. A link from a legal blog to an e-commerce site for gadgets makes no sense even if disclosed. Keep only the connections that provide real navigation value.

Evaluate the content quality on each domain. If some sites in the network show a high bounce rate, low visit duration, or few pages viewed per session, improve them before continuing with linking. Google tolerates high-quality site networks, not farms of mediocre content.

What mistakes should you avoid when establishing a disclosed network?

Do not fall into the trap of anchor over-optimization. Even among disclosed affiliated sites, varying anchors is a good practice. Use natural, branded, generic anchors, and only occasionally exact match anchors.

Avoid systematic links from every page. A relevant contextual link from 10-15% of the articles is more than enough. A site linking to a sister domain from 80% of its pages sends a clear manipulative signal.

Do not create new sites solely to benefit from this rule. Google detects freshly registered domains that publish en masse and then begin to link to a main site. Disclosure does not cleanse a barely disguised PBN strategy.

How can you ensure your network remains compliant with the guidelines?

Use Search Console to monitor manual actions on each domain in the network. A penalty on one site may indicate a quality issue or link strategy that could potentially affect the others.

Analyze the link profile of each site with tools like Ahrefs or Majestic. If a domain in the network receives 90% of its backlinks from other sites owned by the same person, it’s a red flag. Each site should develop its own authority through independent external links.

Test the user value: ask yourself if a visitor would truly find it useful to navigate from one site to another. If the answer is "probably not," the link should not exist, disclosure or not.

• Add a visible mention of common ownership (footer, legal mentions, or dedicated page) on all sites in the network
• Remove links between sites without clear thematic consistency for the user
• Audit the quality of the content on each domain and improve sites with low engagement
• Vary link anchors even between affiliated sites: avoid over-optimization
• Limit inter-site links to 10-15% of the articles at most, in relevant contexts
• Check Search Console monthly for any manual actions on the domains in the network
