How arlong's Ranking Works
Unlike Google's black-box algorithm, arlong scores every result using 8 weighted signals. The score is visible on every result, and the algorithm is fully documented.
Does the page title contain your search words? Exact matches and phrases rank higher. Short or generic titles get penalized.
How often do your search terms appear in the result description? Clustered terms indicate stronger relevance.
Trust scores: Wikipedia (95), Stack Overflow (90), .gov (80). Content farms and spammy domains score low.
Known low-quality sites penalized heavily. AI-generated content patterns, SEO stuffing, and poor formatting detected and demoted.
Newer content gets a boost. Results less than 7 days old score full points. Older content gradually drops off.
The engine guesses what a result is about (tutorial, news, forum) and whether that matches the type of answer you need.
Discussion queries push Reddit results up. Pages baiting with "reddit" in the title get penalized instead.
Clean, short URLs beat long ones with tracking parameters. Query terms in the URL path earn a bonus.
Ranking weights at a glance
Head-to-Head: Real Query Performance
We ran apples-to-apples comparisons across three query categories, measuring relevance and spam-blocking effectiveness against Google and DuckDuckGo.
Discussion Queries (vs, best, review, recommend)
Technical Queries (programming, tools, comparisons)
Shopping Queries (best products, reviews)
Performance summary
Real Query: "best gaming laptop"
We searched the same query across five search engines to see how each renders results. Note the ads, AI summaries, and sponsored content each engine surfaces before organic results.
Unique Features You Will Not Find Elsewhere
Zero Ads, Zero Tracking, Zero AI
No sponsored results. No promoted links. No AI overviews you cannot turn off. Type a query, get real results, scroll zero. arlong states it directly: "No AI summaries to scroll past, no sponsored results, no ads disguised as content."
Content Farm Annihilation
arlong aggressively penalizes known low-quality sites. GeeksforGeeks gets -25 points, Guru99 -20, betanet.net -40. Over 60 AI-generated content phrases are detected and demoted. SEO keyword stuffing is identified and penalized. The result: community-written content rises above SEO spam.
Reddit Boost with Anti-Bait
When your query sounds like you want discussion (vs, best, review, recommend), real Reddit results get a ranking boost. Non-Reddit pages that add "reddit" to their title to game search results are actually penalized by -30 to -25 points. The signal works both ways.
Built-in Crisis and Safety Support
arlong includes comprehensive safety features: suicide prevention with region-specific helplines (US: 988, UK: 116 123, India: 022-2552-1111), disaster safety guides for tornadoes, earthquakes, floods, hurricanes, wildfires, and tsunamis, body-positive redirects for body-negative queries, and medical emergency banners for symptoms like chest pain.
Free, Tokenless API
No signup. No API key. No OAuth. 125 requests per hour per IP. Designed for agents, CLI tools, and LLM integrations. Returns JSON with title, url, snippet, category, score, favicon, date, and info box.
curl "https://arlong-production.up.railway.app/api/search?q=python+tutorial"Browser Sidebar Extension
Available for Chrome and Firefox. Shows arlong results alongside results from Google, Bing, DuckDuckGo, Yahoo, Yandex, Baidu, Brave, Ecosia, Qwant, and Searx. It complements rather than replaces your existing search engine.
How a Query Flows Through arlong
No tracking parameters are attached to outgoing requests. Redis caching keeps it fast. The entire application is a single Python file running Flask behind gunicorn on Railway.
The Verdict
arlong is not trying to replace Google. It is an alternative for people who want privacy without compromise, transparency in how results are ranked, no AI noise cluttering the page, and a free API for tinkerers, agents, and builders. For discussion queries and technical searches, it holds its own against DuckDuckGo and beats it decisively on spam blocking. For general web search, it is a solid daily driver.
