2倍点击率听起来不错，但前提是还有人点击。
8月20日，Google推出了一个让出版商嵌入自家网站的"Preferred Sources"按钮——读者点击后，该出版商就会成为其在Google Search、Discover、Google News中的优先信源，在AI Mode和AI Overviews中更容易被引用和推荐。Google称，今年5月该功能在AI搜索中上线以来，已有34.5万个独立来源被读者选为优先来源，用户点击优先来源的概率是普通来源的2倍。
出版商等这个按钮等了很久。但问题是：在AI搜索已经大规模截流的背景下，一个"白名单"按钮，真的能把流失的流量还回来吗？
AI搜索时代，出版商的流量去哪了？
先看背景。自2025年Google推出AI Overviews以来，出版商网站流量持续下滑。AI Overviews直接在搜索结果页面给出答案，用户不需要再点击任何链接。TechCrunch早在2025年6月就报道过AI Overviews对出版商流量的杀伤，之后多个独立研究确认了这一趋势：用户越来越少离开Google的页面。
这不是Google第一次试图安抚出版商。今年5月，Google在AI Mode和AI Overviews中首次推出Preferred Sources功能，让用户手动标记信任的信源。但那时候读者只能去Google的设置页面手动添加，转化率很低。这次的嵌入按钮让出版商可以直接在自己的网站上放置按钮，读者点一下就完成添加——这是Google第一次主动给出版商"引流工具"。
同时Google还宣布，读者很快可以用自然语言定制Discover信息流——告诉Google"我想多看这个话题"或"少看那个话题"，实时调整推荐内容。Android用户还可以定制Google News的音频简报。
2倍点击率≠2倍流量
表面上看，这是Google的善意：给读者选择权，给出版商流量杠杆。但仔细想，这个机制有几个致命问题。
第一，基数问题。Google说优先来源点击率是普通来源的2倍，但AI Overviews出现后，搜索结果页的总点击率本身就在下降。如果原来100次搜索有40次点击外链，AI Overviews之后可能只有20次，那么"2倍点击率"只是在20次里拿更多份额，跟原来的40次比还是少了。这是一个经典的"变小的馅饼上切更大块"的问题。
第二，马太效应。什么样的出版商能积累最多"优先来源"读者？是本来就有品牌、有流量的大媒体。纽约时报、BBC、卫报这种级别的媒体，会获得最多的读者标记；而中小型独立出版商、垂直领域博客，可能根本没有足够的读者来点击按钮。Preferred Sources机制最终可能加速流量向头部集中，而不是公平分配。
第三，Google仍然控制分发权。即便你被标记为优先来源，Google的AI仍然决定在哪个查询下展示哪个来源的内容。"优先"不是"保证"，Google没有承诺优先来源一定会出现在AI Overviews的引用中。这更像是给出版商一颗安慰剂，而不是真正的流量保证。
"Google给出版商一个按钮说'让你的读者选你当优先'，但它没说的是——如果没人搜完了还点链接，优先又有什么用？"—— 一位数字媒体从业者的吐槽
不过话说回来，这总比什么都没有强。在AI重塑信息分发的大趋势下，出版商需要一切可用的工具来维护读者关系。Preferred Sources按钮的真正价值可能不在流量，而在数据——出版商第一次可以知道哪些读者愿意主动标记自己为信任来源，这是一个高价值的忠诚读者信号。
对内容创作者来说，策略很清晰：把按钮放到网站显眼位置，把"标记我们为优先来源"变成读者运营的一部分，同时不要把鸡蛋放在Google一个篮子里——邮件列表、RSS、私域流量，这些才是真正不受平台控制的渠道。
明天见。
Double the click-through rate sounds great — assuming anyone is still clicking at all.
On August 20, Google rolled out an embeddable "Preferred Sources" button that publishers can place on their websites. Readers who click it designate that publisher as a preferred source across Google Search, Discover, and Google News, making it more likely to be cited and recommended in AI Mode and AI Overviews. Google says that since the feature launched in AI search in May, readers have selected over 345,000 unique sources, and users are twice as likely to click through to preferred sources versus regular ones.
Publishers have been waiting for a tool like this. But here's the question: with AI search already siphoning away massive traffic, can a "whitelist" button really return what's been lost?
In the AI Search Era, Where Did Publisher Traffic Go?
Context first. Since Google launched AI Overviews in 2025, publisher traffic has declined steadily. AI Overviews serves answers directly on the search results page; users don't need to click through to any link. TechCrunch reported on AI Overviews' traffic devastation for publishers back in June 2025, and multiple independent studies have since confirmed the trend: users are leaving Google's pages less and less.
This isn't Google's first attempt to appease publishers. In May, it introduced Preferred Sources within AI Mode and AI Overviews, letting users manually flag trusted outlets. But readers had to navigate to Google's settings page to add sources, making conversion low. This embeddable button lets publishers place the control directly on their sites — one click from a reader and they're added. It's the first time Google has proactively given publishers a traffic-driving tool.
Google also announced that readers will soon be able to customize their Discover feed using natural language — telling Google "show me more of this topic" or "less of that one" to tune recommendations in real time. Android users will also get customizable audio briefings in Google News.
2x CTR ≠ 2x Traffic
On the surface this looks like Google goodwill: giving readers choice, giving publishers a traffic lever. But dig deeper and the mechanism has fatal flaws.
First, the base rate problem. Google says preferred sources get double the CTR, but total CTR from search results pages has been declining since AI Overviews launched. If originally 40 out of 100 searches resulted in an outbound click, post-AI Overviews that might be 20. "Double the CTR" just means a larger share of 20 clicks — still less than the original 40. It's the classic problem of getting a bigger slice of a shrinking pie.
Second, the Matthew Effect. Which publishers will accumulate the most Preferred Source readers? The big brands that already have traffic and name recognition. Outlets like the New York Times, BBC, and Guardian will get the vast majority of reader selections; small independent publishers and niche verticals may not have enough readers to click the button at scale. Preferred Sources could end up accelerating concentration of traffic toward incumbents rather than distributing it fairly.
Third, Google still controls distribution. Even if you're marked as a preferred source, Google's AI still decides which sources appear for which queries. "Preferred" isn't "guaranteed" — Google hasn't promised preferred sources will always appear in AI Overview citations. This feels more like a placebo for publishers than a genuine traffic guarantee.
"Google gives publishers a button that says 'have your readers mark you preferred,' but it doesn't say — if nobody clicks through to links after searching anymore, what does preferred even mean?"— A digital media operator's roast
That said, something is better than nothing. As AI reshapes information distribution, publishers need every tool available to maintain reader relationships. The real value of the Preferred Sources button may not be traffic — it's data: for the first time, publishers can see which readers actively flag them as a trusted source, a high-value signal of loyal readership.
The strategy for content creators is clear: place the button prominently, turn "mark us preferred" into a reader retention play, and don't put all eggs in Google's basket — email lists, RSS, private channels are the channels that platforms can't control.
See you tomorrow.
Google给出版商的优先来源按钮，是在变小的馅饼上切更大的块——2倍点击率，弥补不了AI搜索截走的总流量。
