Bing Announces Link Penalties

Published

on

Bing announced a new link penalties. These link penalties are focused on taking down private blog networks (PBNs), subdomain leasing and manipulative cross-site linking.

Inorganic Site Structure

An inorganic site structure is a linking pattern that uses internal site-level link signals (with subdomains) or cross-site linking patterns (with external domains) in order to manipulate search engine rankings.

While these spam techniques already existed, Bing introduced the concept of calling them “inorganic site structure” in order to describe them.

Bing noted that sites legitimately create subdomains to keep different parts of the site separate, such as support.example.com. These are treated as belonging to the main domain, passing site-level signals to the subdomains.

Bing also said sites like WordPress create standalone sites under subdomains, in which case no site level signals are passed to the subdomains.

Examples of Inorganic Site Structure

An inorganic site structure is when a company leases a subdomain in order to take advantage of site-level signals to rank better. There have been

Private blog networks were also included as inorganic site structure

Domain Boundaries

Bing also introduced the idea of domain boundaries. The idea is that there are boundaries to a domain. Sometimes, as in the case of legitimate subdomains (ex. support.example.com), those boundaries extend out to the subdomain. In other cases like WordPress.com subdomains the boundaries do not extend to the subdomains.

Private Blog Networks (PBNs)
Bing called out PBNs as a form of spam that abuse website boundaries.

“While not all link networks misrepresent website boundaries, there are many cases where a single website is artificially split across many different domains, all cross-linking to one another, for the obvious purpose of rank boosting. This is particularly true of PBNs (private blog networks).”

Subdomain Leasing Penalties

Bing explained why they consider subdomain leasing a spammy activity:

“…we heard concerns from the SEO community around the growing practice of hosting third-party content or letting a third party operate a designated subdomain or subfolder, generally in exchange for compensation.

…the practice equates to buying ranking signals, which is not much different from buying links.”

At the time of this article, I still see a news site subdomain ranking in Bing (and Google). This page belongs to another company. All the links are redirected affiliate type links with parameters meant for tracking the referrals.

According to Archive.org the subdomain page was credited to an anonymous news staffer. Sometime in the summer the author was switched to someone with a name who is labeled as an expert, although the content is still the same.

So if Bing is already handing out penalties that means Bing (and Google who also ranks this page) still have some catching up to do.

Cross-Site Linking

Bing mentioned sites that are essentially one site that are broken up into multiple interlinking sites. Curiously Bing said that these kinds of sites already in violation of other link spam rules but that additional penalties will apply.

Here’s the kind of link structure that Bing used as an example:

Bing used the above example to illustrate interlinked sites that are really just one site.

That link structure resembles the structure of interlinked websites that belong to the same company. If you’re planning a new web venture, it’s generally a good idea to create a site that’s comprehensive than to create a multitude of sites that are focused on just a small part of the niche.

Curiously, in reference to the above illustration, Bing said that kind of link structure was already in violation of link guidelines and that more penalties would be piled on top of those:

“Fig. 3 – All these domains are effectively the same website.
This kind of behavior is already in violation of our link policy.

Going forward, it will be also in violation of our “inorganic site structure” policy and may receive additional penalties.

Takeaway

It’s good news to hear Bing is improving. Competition between search engines encourage innovation and as Bing improves perhaps search traffic may become more diversified as more people switch to Bing as well as other engines like DuckDuckGo.

Google December Product Reviews Update Affects More Than English Language Sites? via @sejournal, @martinibuster

Published

on

Google’s Product Reviews update was announced to be rolling out to the English language. No mention was made as to if or when it would roll out to other languages. Mueller answered a question as to whether it is rolling out to other languages.

Google December 2021 Product Reviews Update

On December 1, 2021, Google announced on Twitter that a Product Review update would be rolling out that would focus on English language web pages.

The focus of the update was for improving the quality of reviews shown in Google search, specifically targeting review sites.

A Googler tweeted a description of the kinds of sites that would be targeted for demotion in the search rankings:

“Mainly relevant to sites that post articles reviewing products.

Think of sites like “best TVs under $200″.com.

Goal is to improve the quality and usefulness of reviews we show users.”

Google also published a blog post with more guidance on the product review update that introduced two new best practices that Google’s algorithm would be looking for.

The first best practice was a requirement of evidence that a product was actually handled and reviewed.

The second best practice was to provide links to more than one place that a user could purchase the product.

The Twitter announcement stated that it was rolling out to English language websites. The blog post did not mention what languages it was rolling out to nor did the blog post specify that the product review update was limited to the English language.

Product Review Update Targets More Languages?

The person asking the question was rightly under the impression that the product review update only affected English language search results.

But he asserted that he was seeing search volatility in the German language that appears to be related to Google’s December 2021 Product Review Update.

This is his question:

“I was seeing some movements in German search as well.

So I was wondering if there could also be an effect on websites in other languages by this product reviews update… because we had lots of movement and volatility in the last weeks.

…My question is, is it possible that the product reviews update affects other sites as well?”

John Mueller answered:

“I don’t know… like other languages?

My assumption was this was global and and across all languages.

But I don’t know what we announced in the blog post specifically.

But usually we try to push the engineering team to make a decision on that so that we can document it properly in the blog post.

I don’t know if that happened with the product reviews update. I don’t recall the complete blog post.

But it’s… from my point of view it seems like something that we could be doing in multiple languages and wouldn’t be tied to English.

And even if it were English initially, it feels like something that is relevant across the board, and we should try to find ways to roll that out to other languages over time as well.

So I’m not particularly surprised that you see changes in Germany.

But I also don’t know what we actually announced with regards to the locations and languages that are involved.”

Does Product Reviews Update Affect More Languages?

While the tweeted announcement specified that the product reviews update was limited to the English language the official blog post did not mention any such limitations.

Google’s John Mueller offered his opinion that the product reviews update is something that Google could do in multiple languages.

One must wonder if the tweet was meant to communicate that the update was rolling out first in English and subsequently to other languages.

It’s unclear if the product reviews update was rolled out globally to more languages. Hopefully Google will clarify this soon.
