How is Google truly detecting doorway pages with its new algorithm?

What defines a doorway page according to Google?

A doorway page is a web page created to rank for specific queries without offering unique content or real added value. These pages serve as entry points to subsequently redirect the user to a final destination, or they exist in multiple nearly identical versions to capture traffic on keyword variations.

The intent behind these pages is purely SEO: maximizing visibility on the search engine, not enhancing user experience. Google has considered them manipulative since its early quality guidelines, but automated detection has always posed a technical challenge. This new algorithm aims to automate this detection at scale.

Why is Google launching a dedicated algorithm now?

Doorway pages have evolved. Coarse techniques (automatic redirects, single-keyword satellite pages) have given way to more sophisticated approaches: mass geolocated pages, AI-generated landing pages with minimal variations, or dynamic content that adapts based on the detected query.

These new forms of doorway pages are harder to detect manually. The volume of automatically generated content is skyrocketing, and human review teams can no longer keep up. An algorithm capable of spotting semantic duplication patterns and site structures designed to capture without serving becomes essential to maintain quality in search results.

Which types of sites are primarily targeted?

Google does not provide an exhaustive list, but sectors historically keen on doorway pages are in the spotlight: lead generation (locksmiths, plumbers, movers), real estate, insurance, legal services, and any site that deploys hundreds of pages targeting "[service] + [city]" with nearly identical content.

Affiliate sites that create pages per product/brand without their own editorial content, or comparators that multiply URLs for each combination of criteria, are also affected. The decisive criterion remains the absence of distinctive added value from one page to another.

• Doorway pages are designed to rank, not to serve the end user.
• The algorithm targets semantic duplication patterns and manipulative site structures.
• The lead generation and affiliate sectors are historically the most exposed.
• The line between legitimate geolocated optimization and doorway pages remains subjective and undocumented by Google.
• No quantitative criteria (number of pages, similarity rates) are officially communicated.

Is this statement consistent with field observations?

Yes and no. There have indeed been dramatic drops in visibility observed on sites with massive geolocated structures, especially in lead generation. Some sites lose 60-80% of their organic traffic overnight, without any manual action noted in Search Console.

However, the problem is that Google provides no objective criteria to distinguish a doorway page from a legitimate page. Creating 50 pages "locksmith + [city]" with unique content per city, local testimonials, and specific practical information, is that a doorway page? [To be confirmed] as Google remains intentionally vague. This lack of precise definition leaves a massive gray area where many legitimate SEO strategies can be targeted.

What nuances should be added to this announcement?

First nuance: the algorithm detects patterns, not intentions. A site may have technically similar pages for good reasons (product catalog structure, regional service pages with real local teams) and find itself penalized if the algorithmic signals are misinterpreted.

Second nuance: Google talks about "added value", but this concept remains subjective. For a user searching for "locksmith Paris 15", a dedicated page with hours, a specific service area, and local rates has value, even if the overall site structure repeats this model across 20 districts. Will the algorithm make this distinction? Nothing guarantees that.

Third nuance: no mention of a grace period or reconsideration process. If your site is affected, you fix it, wait, and hope. No timeline, no feedback, no transparency.

In what cases does this rule not really apply?

Large e-commerce sites or platforms with established authority seem less impacted, even when they deploy thousands of product pages or very similar landing pages. Amazon, Booking, or Tripadvisor massively generate nearly identical content by structure, but their domain authority and user signals (CTR, dwell time, conversions) protect them.

Similarly, institutional or governmental sites that multiply pages by region or administrative service are never targeted, even if the differential added value is sometimes weak. The algorithm likely incorporates trust and authority factors that create a two-speed treatment.

What should be prioritized when auditing your site?

Start by mapping all pages that follow a repetitive template with minimal variations: pages by city, by product, by service + location. List them, calculate their textual similarity rate (you can use tools like Copyscape or Siteliner), and identify those that share more than 70% common content.

Next, evaluate the real added value of each group of pages. Does each page provide unique information, a local testimonial, specific data, differentiated hours, or unique visuals? If the only difference is the city name in the H1 and three occurrences in the text, you are in danger.

What concrete corrective actions should be implemented?

First action: consolidate pages that do not provide unique value. Instead of 50 pages "locksmith + [city]", create a main page per large geographic area with an interactive map and sections by sub-area. Redirect the old URLs with a 301.

Second action: enrich the content of the pages you keep. Add real differentiating elements: interviews with local clients, photos of projects in the area, partnerships with local businesses, events, specific demographic or economic data. The content must justify the existence of the page as a separate entity.

Third action: monitor user signals. If your geolocated pages have a bounce rate > 70% and a time on page < 30 seconds, it’s a clear signal that they are not serving the user. Google sees it too. Improve the UX, add clear CTAs, and facilitate navigation.

How can you verify that your site is compliant?

There is no official validation from Google to confirm that your site does not contain doorway pages. You must manually audit and ask yourself: "If I land on this page from Google, do I get a complete answer to my query, or is it just an intermediate step to push me elsewhere?"

Use Search Console to identify pages with high impressions but low CTR: this may indicate that Google displays them but users do not click, a sign that the title/description does not match the real content. Also, monitor pages with plummeting traffic without any manual action noted.

• Audit all pages following a repetitive template and calculate their similarity rate.
• Consolidate pages without unique added value by 301 redirects to consolidated pages.
• Enrich retained pages with real differentiating content (testimonials, visuals, local data).
• Monitor user signals (bounce rate, time on page) to detect weak pages.
• Check in Search Console for pages with high impressions but low CTR.
• Avoid any massive automated creation of pages through simple keyword variations.
