Contact usGooglebot rendering
Álvaro Peña de Luna Googlebot starts with a 412×732 viewport and around 5 seconds in stretches it to the page height, capped at 10 million pixels and with no scrolling. It loads every lazy image down the page; in a carousel, only up to about 1,500 px.

Google Discover traffic
Álvaro Peña de Luna At Search Central Live Barcelona Google went over what Discover asks for. I crossed it with 90 days of Search Console from 49 client sites: 42 have not a single impression, and almost all the portfolio's traffic came from one article in four days.

AI shopping on Google
Álvaro Peña de Luna Google is telling Shopify stores their products can now be bought inside AI Mode and Gemini, without going through their site and without having asked. Today only in the US, Canada and Australia. What is worth deciding before it arrives.

Bot impressions in Search Console
Álvaro Peña de Luna Last week I said Search Console is the plan B when rank tracking gets expensive. Here is the small print: those tools' crawlers also generate impressions, and on one of our domains they are 86%.

Rank tracking and SERP scraping
Álvaro Peña de Luna Google now routes almost every SERP link through google.com/goto, and resolving one keyword costs up to 1,000 requests. I crossed both sources over the same portfolio to see how much the report moves when you swap one for the other.

Reddit as a source for AI recommendations
Álvaro Peña de Luna From 3.83% to 0.52% of ChatGPT Search citations in seven days, caused by an internal OpenAI change. Nobody at Reddit did anything wrong, and nobody could have prevented it.

Google Preferred Sources
Álvaro Peña de Luna Two lines of code and your readers mark you as a preferred source without leaving the page. It works outside the US, but two requirements may rule you out.

Sources behind AI citations
Álvaro Peña de Luna We looked at what ChatGPT, Perplexity and AI Overviews cite across 39 projects in different sectors. The brand is the leading source about itself in only 13 of 39, and the one in charge is almost never the competitor.

Watermarks in AI-generated content
Álvaro Peña de Luna Anthropic now marks every text it generates and the mark survives copy and paste. It degrades with paraphrasing, so it does not stop mass spam: it marks whoever uses AI honestly.

Bing Search APIs
Álvaro Peña de Luna Migrating to JSON is an afternoon of work. The real point is elsewhere: ChatGPT's search leans on Bing's index, so Webmaster Tools is now an AI visibility diagnostic.

ChatGPT market share in Spain
Álvaro Peña de Luna From 90% of AI assistant users in Spain to 45% in three years, according to Sensor Tower. Optimizing only for ChatGPT means optimizing for half the market.

Information gain in content
Álvaro Peña de Luna A study measures how much original information the top 3 brings and the median sits at 52 out of 100. Pages with more than 15 unique data points score 62; those with none, 40.

Toggle to block content in AI Overviews and AI Mode
Álvaro Peña de Luna Google shipped the toggle to opt out of AI Overviews alongside an AI report that only shows impressions. It lets you decide whether to block, without showing the clicks at stake.
