Gemini’s grounding context has a completely new format which I don’t fully understand yet. It seems custom to different prompt types and breaks outside the old index 1, index 2…etc model. Sharing the discovery for now hoping to hear more from the community and add to it later.

As ChatGPT, Claude, Grok, and Perplexity reshape how people discover answers, products, and services, a new form of SEO is emerging: visibility inside AI-powered search. It's no longer enough to write for algorithms—you need to write for AI models that read, summarize, and recommend content. If your website isn't showing up in AI-generated answers, you're invisible to a growing portion of users. The good news? You can fix that—by using the best AI tools for SEO. A retro-futuristic space traveler looking up at multiple glowing thought bubbles, set in. Why GPT Search Is Different From Google Search. Traditional SEO focuses on helping search engines index your content and rank it in a list of results. But GPT-powered search—like what you get in ChatGPT or Claude—doesn't show 10 blue links. It gives a single-synthesized answer. Instead of driving traffic through ranking, AI models drive visibility through referencing and summarizing. That means your content n"

More known for their bikes than their apparel, Specialized also makes a stellar kit with their Prime series. This jersey is made from an optimized mix of nylon and elastane that feels smooth and luxurious against your skin while also having an attractive matte finish. The main body fabric is perfectly weighted for spring and fall rides, with a lightweight stretch mesh under the arms and at the\nbottom hem. Specialized notes that the jersey has cooling properties––it is indeed cool-to-the-touch––but I'd likely opt for something slightly lighter weight for peak summer rides.\n... (2025-01-09) All Day Jersey<br><br> ... As the name suggests, this is a jersey that's designed for all-day comfort. Updated this year with an improved fit and sustainable recycled materials, the All Day Jersey is a standout piece from Attaquer for cyclists of all levels. The sleeves are made of an ultra-lightweight mesh with a raglan cut, allowing for a very versatile fit over your shoulders and down the arm. The body and back feature a more supportive fabric, providing a secure feel for both the fit and the jersey's pockets.\n...

How do you determine the difference between a “cyclist” and the “ guy on a bike”? As bike blogger Eben Weiss would say, the former is a type of person, while the second is\na coincidence or a circumstance. He'd tell you someone is a “cyclist” when they either begin riding a bike even when they don't have to, or when they buy a floor pump. Preferably both. I'd offer another criteria: you become a cyclist when you own a complete kit. That's right––not a bike, a kit. That means at the least a bib and a jersey, and usually also other unnecessarily expensive gear like pedals, big honking sunglasses, and a bike computer. I\nonce got a new bike, showed it to my cyclist friend, and was immediately asked: “Ok, but what kit are you going to pair with it?” True story. Cyclists can be closested fashion divas. After all, they (we?) are riding around on a two-wheeler in skin-tight spandex. But in fairness, the right kit can make the difference between feeling comfortable and confident for hours on end, or wishing you could pull off to the side and call an Uber home. Over the last few years as cycling\nhas grown in popularity, so too have a number of brands that have made cycling cool by bringing modern designs and premium materials to bibs, jerseys, and the like. Cyclists today have a wealth of options when it comes to selecting their gear, and it can get overwhelming trying to balance style, comfort, performance, and budget. That's why I...
