Three glass orbs — a speed gauge, a chart and a sparkle — beaming into one prism Most builders stop at "here's your app." Aura keeps going: it measures your live app with **Google PageSpeed**, studies your market with **Semrush**, and hands both to **Gemini 3.8 Flash**, which turns them into one page-by-page plan the AI Builder can carry out with a single tap. ## The three parts Google's own Lighthouse test, on phone and computer: speed, SEO, accessibility and best-practice scores, Core Web Vitals and a fix list. What people actually search for: your keywords, estimated monthly visits, authority score, linking sites, competitors, keyword gaps and quick wins. Reads your live pages, the PageSpeed results and the Semrush data together, and writes one prioritized, page-specific plan. ## Why the combo matters Each tool alone tells you half the story. PageSpeed says *what's slow* but not what to write. Semrush says *what people search* but not what's broken on your pages. Static checks say *what's missing* but not what matters most. Gemini 3.8 Flash connects them — so the plan says, for example, "compress the hero image on your home page, and add a section answering the question your competitors rank for." A ranked glass checklist next to a search results page with the top result rising ## How it works Aura checks every page (titles, descriptions, headings, content length, sitemap, robots, icons, share images) and runs Google PageSpeed on phone and computer. Semrush adds your keywords, competitors and quick wins — searches you nearly rank for. Gemini 3.8 Flash (medium reasoning) writes one prioritized plan, page by page. Tap **Fix** and the AI Builder applies the plan in one build. After the build, PageSpeed runs again. If phone or computer is still under 90, Aura offers a second speed round (up to two). ## One-tap actions in the SEO tab | Button | What it does | | - | - | | **Optimize everything** | PageSpeed fixes, missing files (sitemap, robots, manifest, icons), on-page content checks and Semrush quick wins in one run | | **Full SEO + GEO pass** | Tunes your app for Google *and* for AI answer engines | | **Refresh** | Pulls the latest numbers | ## What it costs * Reading your SEO numbers and checks is free. * The Gemini review and each **Fix** build use credits, shown before you confirm. * Semrush data is cached for 24 hours and needs your app on its own domain. Want a written review instead of automatic fixes? Run [`/seo-review`](/builder/skills) — it starts from these same findings. ## Common questions No. Aura provides PageSpeed, Semrush data and Google Search Console setup for you. Semrush data appears once your app is live on its own domain. New sites can take a few days to show up. Up to two. After each fix, PageSpeed re-measures; a second round is offered only if a score is still under 90.
