LinkScope – Link Type Highlighter

Instantly highlight dofollow, nofollow, sponsored & UGC links in beautiful colors. Fully customizable.

🔍 LINKSCOPE – LINK TYPE HIGHLIGHTER | SEE EVERY LINK'S TRUE SEO VALUE INSTANTLY Stop guessing. Start seeing. LinkScope instantly highlights every link on any webpage — dofollow, nofollow, sponsored, and UGC — each in a beautiful, distinct color. Built for SEOs, link builders, content marketers, bloggers, and developers who need to audit link profiles in seconds, not hours. No subscriptions. No sign-up. No data collection. Just install and see. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ WHY SEO PROFESSIONALS NEED THIS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every link carries a hidden label — dofollow, nofollow, sponsored, or UGC — that determines whether it passes SEO authority or not. Those labels are buried inside HTML code, invisible to the naked eye. LinkScope pulls back the curtain. The moment you install it, every link on every page is instantly color-coded by type. What used to take 20 minutes of inspecting source code now takes zero seconds. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎨 FOUR LINK TYPES. FOUR BEAUTIFUL COLORS. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🟢 DOFOLLOW — Emerald green The most valuable links in SEO. Dofollow links pass PageRank and domain authority from one site to another. Every SEO professional hunts these. LinkScope highlights them in bright green so you spot every single one instantly. 🔴 NOFOLLOW — Red The rel="nofollow" attribute tells Google not to pass link equity. Nofollow links have referral traffic value but don't directly boost rankings. LinkScope marks every one in red so you never confuse it with a dofollow. 🟡 SPONSORED — Amber Introduced by Google in 2019, rel="sponsored" marks paid links, ads, and affiliate partnerships. Missing these means misreading a site's editorial vs commercial link ratio. LinkScope highlights them in warm amber. 🟣 UGC — Purple The rel="ugc" attribute marks links in comments, forums, and community content. These carry different signals than editorial links. LinkScope highlights UGC links in purple so you always know their origin. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✏️ FIVE HIGHLIGHT STYLES — YOUR CHOICE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. BACKGROUND — Soft color wash behind link text. Clean and readable. Default style. 2. UNDERLINE — Colored underline beneath each link. Subtle and elegant. 3. BORDER — Bold colored border beneath each link. Clear visual separator. 4. BOLD — Link text becomes bold and colored. Great for reading alongside analysis. 5. OUTLINE — Colored box surrounds each link. Maximum visibility for dense pages. Switch between styles with one click. Saved instantly across all tabs. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌙 AUTOMATIC DARK MODE — SEPARATE PALETTES FOR EACH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most tools look terrible on dark websites. LinkScope automatically detects your system theme and applies a fully separate, optimized color palette for light and dark mode. LIGHT MODE: Deep emerald, strong red, rich amber, deep purple. DARK MODE: Bright mint, coral red, golden yellow, lavender purple. You can customize both palettes independently. Adjustments to one never affect the other. Colors switch automatically when your system theme changes. No other link highlighter on the Chrome Web Store does this. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 LIVE PAGE STATS — INSTANT LINK AUDIT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every time you open the LinkScope popup you see a live count of every link type on the current page. Instantly answer questions that used to require expensive tools: → How many outbound links on this site are dofollow? → Does this publisher mark all external links nofollow? → How many sponsored links does this article have? → What's the editorial vs paid link ratio on this page? For link builders prospecting targets, this is a game-changer. Qualify any website in seconds without opening dev tools or running a crawl. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 WHO IS LINKSCOPE FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SEO PROFESSIONALS — Stop right-clicking every link to inspect source code.

With LinkScope: open page, see everything in under one second. VS AHREFS / SEMRUSH / MOZ Those tools are powerful for historical backlink databases but cost $99–$400/month and require you to enter URLs and wait for results. LinkScope is real-time, in-browser, and free. Use both together — they're complementary, not competing. VS OTHER NOFOLLOW EXTENSIONS Basic nofollow extensions only detect one link type with a single harsh color, zero customization, and no dark mode support. LinkScope detects four link types, offers five highlight styles, full color customization, separate dark/light palettes, and live stats. There is no comparison. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔐 PERMISSIONS — ONLY WHAT WE NEED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ STORAGE — Saves your color and style preferences.
