What Is BLUF? How to Write Bottom Line Up Front (+ Free Rewriter Tool)
BLUF stands for “bottom line up front”. You put your main point (or conclusion or key finding) in the first sentence, then the detail the reader needs to act on it, then background only if they need it. It comes from the US Army, whose writing regulation tells soldiers to put “the main point at the beginning of the correspondence”. Orders had to be read and acted on fast, so the conclusion went first. The same habit now helps with AI search, because AI tools also pay the most attention to the start of a page. Here are some examples of BLUF in action: Email Before: “Hi Mark, as you know we’ve been looking at options for our webinar platform… Would you be able to approve the annual plan?” After: “Hi Mark, can you approve the Livestorm annual plan ($2,400) by Friday? It was the cheapest of the three tools

How Stable Are AI Citations? 10 Things We Learned Tracking 37,500 Citations
Treat citation volatility as normal. It seems to be a built-in trait of AI answers, and it may change significantly with model updates. So, aim to appear more often over time, not to hold every citation without interruption. Because of that, AI citations might not be a great AEO KPI—brand mentions make a better candidate since they are more stable. Don’t judge AI visibility from one check. 50–83% of citations are gone the next day, but about 75% of those come back within 20 days. Count how many of the last seven days you were cited. Judge a drop by what came before it. A citation that held for 8+ days almost always returned (96–99%). A one-day citation never came back 34–41% of the time. Keep doing the SEO basics for Google’s AI tools. Rankings, traffic and a title that answers the question go with longer-lasting citations. More DR or

How To Analyze Server Logs for AI Search
Step 6: Investigate the 499s Let’s go back to the third row from our earlier log example: 23.102.140.7 [12/Aug/2026:14:32:07 +0000] “GET /guides/pricing HTTP/1.1” 499 0 “-” “…ChatGPT-User/1.0” rt=31.412 cache=MISS The 499 status code means “client closed request.” The requester hung up before your server finished sending it. This isn’t an official HTTP status code; rather, nginx invented it, and many CDNs and load balancers adopted it (some systems log it under a different label). In this example, ChatGPT-User disconnected after more than 31 seconds on a cache miss, and the server sent no bytes. It makes response time worth investigating, though the code alone doesn’t tell you why the requester disconnected. This is why I think 499 is one of the most interesting status codes in your logs because it records a decision someone else made about you. However, it’s also easy to miss. Monitoring focused on 500-level server errors

AI Discoverability, Page types, and more
We’ve got 5 updates this month, from a brand-new AI Discoverability category in Site Audit to Page types in Site Explorer, and more. Site Audit AI Discoverability issues AI Discoverability is a new issue category in Site Audit. It checks whether AI crawlers like ChatGPT and Claude can reach, read, and cite your pages.

What It Is & How to Start in 2026
Affiliate marketing is still one of the simplest ways to make money online. You recommend products you genuinely rate. When someone buys through your link, you get a commission. You don’t have to make the product, hold stock, handle shipping, or deal with refunds. In this guide, I’ll show you how to think about affiliate marketing in 2026, what still works, what has changed, and how to start without building the kind of site Google or readers can easily ignore. What is affiliate marketing? Affiliate marketing is when you promote another company’s product or service. If someone buys through your link, you earn a commission. For example, Serious Eats earns a commission when you click through to any of these links and make a purchase. So if you clicked through and bought their top pick, the $69 Yosukata carbon steel wok, on Amazon, Serious Eats would earn about $3.10 at

A New (Old) Strategy for Search
Gone are the days of compounding search traffic, ordinal search rankings, forecasting based on predictable click-through and conversion rates. Today, your content pages are grist for the AI mill, their contents scraped from the page, blended together with competing pages, and shown to the user—if you’re lucky—in a context and format controlled entirely by a third party. Forgotten is the handshake agreement that good content will be rewarded by website visitors. Instead, most people who interact with your content will do so through an intermediary like Google’s AI Overviews or a ChatGPT response. But most pages are still created with the assumption that people will visit them directly. How does content change if we abandon that idea? Headless content marketing I see more companies asking and answering this question, creating pages of information with the assumption that few people will ever visit them. Instead, they seem intended solely for retrieval
