The Dark Side of the Force: Skanky Links

Google’s View on Link Value and Spam Resistance

When the Search Engine Strategies conference opened its doors yesterday, one of the most anticipated panels featured WebGuerrilla president Greg Boser - known in some circles for his aggressive link‑building tactics - alongside Google’s Director of Technology, Craig Silverstein. Silverstein, who joined Google five years ago, is responsible for many of the algorithmic innovations that keep the search engine’s results relevant. The session was a rare opportunity to hear an insider explain how Google actually measures a page’s importance through links.

Silverstein emphasized that a page’s weight is essentially the sum of the importance of every other page that links to it. He described the process as a “simple yet powerful formula” that rewards pages that are referenced by high‑quality sites and discourages manipulation. According to him, this approach is inherently spam‑resistant because it’s difficult to inflate a page’s rank by building a network of low‑value links that all point back to each other. Instead, Google looks for natural, organic link paths that span across a web of trusted content.

While the underlying mathematics have been around for a while, Silverstein’s confirmation from someone who actually builds the system adds credibility to the advice often found in SEO blogs. He pointed out that the algorithm has evolved; previously, link farms could slip through because the system didn’t scrutinize link quality as deeply. Now, even if you have a large number of backlinks, Google evaluates them individually and weighs them based on domain authority, topical relevance, and trust signals.

The Googlebot also displays a clear preference for content that is visible to human visitors. That is why Google has phased out meta tags as a ranking factor. Meta tags can be easily manipulated, and they do not provide useful information to users. Instead, the focus has shifted to on‑page elements like title tags, header tags, and body copy that give both humans and crawlers insight into what the page is about. This shift underscores the importance of producing genuine, high‑quality content that answers real questions.

Silverstein also touched on domain naming conventions, noting that hyphenated domains have fallen out of favor as a spam tactic. He explained that Google’s parsing logic treats hyphens as spaces, allowing keyword phrases to be parsed correctly, whereas underscores are considered part of a single word. For example, a domain like best-summer-gear.com will be read as “best summer gear,” whereas best_summer_gear.com is read as one long word. In practice, this means that when you register a domain that includes a keyword, hyphens are the safer bet. That said, keyword stuffing in domain names is still frowned upon; the key is to keep the name natural and memorable.

In the end, the panel’s main takeaway was that Google rewards genuine link building that stems from real, valuable content. The algorithm is designed to surface links that help users navigate to trustworthy information, not to reward artificial link schemes. When you align your strategy with these principles, you’ll be in sync with Google’s own goals for a cleaner, more useful search ecosystem.

Defining and Avoiding “Skanky Links” – Tactical Advice for Clean Profiles

When Silverstein warned against “link skanks” and urged attendees to steer clear of “bad neighborhoods,” the room erupted in laughter. The phrase instantly became an inside joke for the remainder of the panel, but the lesson behind it was serious. The term refers to any backlink that appears deceptive or low quality - link farms, paid link exchanges, or sites that don’t align with the content you’re promoting. Google’s algorithms have evolved to detect these patterns, and penalties can be severe.

One practical rule Silverstein repeated was to prioritize descriptive anchor text. Instead of generic phrases like “click here,” he suggested using meaningful keywords that provide context for both users and search engines. For example, if you’re linking to a guide about healthy eating, an anchor such as “balanced diet tips” is far more valuable than “learn more.” Anchor text that mirrors the destination page’s title or main keyword signal relevance and improve crawlability.

He also emphasized the importance of building links from sites that are topically related. When a health blog links to your nutrition guide, it feels natural to readers and signals relevance to Google. Conversely, if a gaming website suddenly links to your finance page, it may trigger suspicion. The same principle applies to link placement: a link buried in a comment section of a random forum is less trustworthy than one in a well‑structured article.

Silverstein’s “avoid anything that looks skanky” mantra includes several specific red flags:

• Excessive reciprocal linking where two sites continually link to each other in a closed loop.
• High volume of outbound links from a single page that appear spammy.
• Links from domains with low authority, many ads, or irrelevant content.
• Use of cloaking or hidden links that only the crawler can see. He advised to audit your backlink profile regularly using tools like Ahrefs or SEMrush to spot any sudden spikes or suspicious sources. If you find a pattern that matches the red flags, it’s time to disavow those links through Google Search Console.

  Beyond the mechanics of anchor text and domain selection, Silverstein touched on the human side of link building. He argued that the best links come from genuine relationships - content creators who genuinely want to share your valuable resource. This might mean contributing a guest post that adds new insight to their audience or providing a case study that they can reference. When the link is part of a meaningful collaboration, it carries more weight than a paid arrangement that feels transactional.

  Silverstein also warned about the “old” strategy of relying on the Open Directory Project (ODP). He said that many ODP sections are dead or barely maintained. In the age of social media and content discovery platforms, there are richer avenues to explore. A well‑crafted post on Medium, a resource share on Reddit, or a mention in a niche industry forum can yield more reliable backlinks. The key is consistency: “submit, move on, and forget about it” is a reminder that link building is not a one‑off task; it needs to be part of an ongoing content strategy.

  In essence, the advice is clear: focus on relevance, transparency, and quality. By following these guidelines, you’ll build a link profile that stands up to Google’s scrutiny and serves real users.

  Greg Boser’s Three‑Step Blueprint for Long‑Term Link Building

  Greg Boser, a figure whose name is synonymous with aggressive link‑building, shared a set of principles that might surprise those who assume he’s all about black‑hat tactics. He outlined three goals that form the backbone of his approach - each aimed at creating a sustainable and self‑reinforcing link ecosystem.

  First, Boser advocates eliminating reciprocal linking whenever possible. The goal is to have other sites link to you naturally, without a back‑and‑forth arrangement that can look suspicious to search engines. He recommends focusing on content that genuinely deserves a link and letting that content do the marketing. By producing a resource that is both valuable and shareable, you’ll attract inbound links organically. That way, the link profile remains robust even after a particular campaign or promotional push ends.

  The second goal revolves around establishing a strong inbound link structure that directly boosts organic search performance. Boser stresses that the architecture of your backlinks matters as much as the number of them. A diversified link profile that includes editorial links, resource pages, and contextual links within high‑authority domains provides a stronger signal to Google. He also notes that the quality of anchors and relevance of the linking pages play a decisive role. By creating a web of high‑quality connections, you create a virtuous cycle where each new link helps elevate the others.

  Finally, Boser’s third goal is about longevity. He acknowledges that campaigns - whether it’s a paid press release or a temporary sponsorship - are transient. To maintain relevance after the campaign ends, Boser recommends building a network of link‑building programs that are tied to content syndication, web tools, or even desktop applications. For instance, if you develop a free plugin or a handy web tool, other sites will naturally link back to the tool’s page. This creates a continuous source of backlinks that persist over time, independent of marketing spend.

  Boser also warns against several common pitfalls that can trigger penalties. Guestbook spamming, log file spamming, and blog posting just for the sake of a link are all risky. He underscores that even though there are entire industries built around link spamming, the search engines are tightening their defenses. The best defense, he says, is to stay one step ahead by building real value for users. The lesson is to avoid any tactic that feels “too similar” to black‑hat methods. If you’re not sure, err on the side of caution.

  One of the more unexpected pieces of advice from Boser is the endorsement of nonprofit backlinks. He explained that links from well‑managed nonprofit organizations carry a high level of trust, and they’re often inexpensive or even free. Many nonprofits provide sponsorship opportunities or resource links for a nominal fee, and these links tend to be evergreen. Boser recommends checking sites like Network for Good to find reputable nonprofits that might be willing to add a link. The advantage is that such links are usually more durable and less likely to be penalized.

  He also cautioned attendees against relying on the Open Directory Project. Though ODP used to be a staple for link building, many of its sections are outdated. Boser’s advice is pragmatic: “submit, move on, and forget about it.” He encourages focusing on fresh, high‑quality platforms that are actively used by users and search engines alike.

  Overall, Boser’s three‑step strategy offers a blueprint that balances ambition with sustainability. By concentrating on organic inbound links, structuring your link profile strategically, and ensuring long‑term relevance, you can build a link ecosystem that withstands algorithm updates and stays profitable.
