Components: Social Share Buttons

Guides implementation of share buttons that let users share the current page (article, post, product) to social platforms. Distinct from social profile links (footer links to your brand's X, LinkedIn, etc.) — share buttons share this content.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope

• - Share buttons: Share current page URL to X, LinkedIn, Facebook, WhatsApp, etc.
• Not social profile links (e.g. "Follow us on X") — those live in footer/nav

Why It Matters

• - Websites with visible social share icons tend to see higher social engagement
• Share buttons amplify reach; Open Graph and Twitter Cards control preview — see open-graph, twitter-cards

Placement (Article Pages)

Fewer, better-placed buttons outperform scattered placement. Research: removing 80% of buttons and repositioning the remaining 20% at high-emotion moments can 3× conversion on share actions.

Placement	Best For	Notes
After first paragraph	Most articles	Catches speed-readers; visible early
Sticky sidebar

Long-form (desktop) | Always visible; consider hiding on mobile |
| Below title / hero | Short posts | High visibility |
| End of article | All | Natural completion point; pair with CTA |
| Mid-article (after key insight) | Long content | Place at friction points (after surprising stat, before CTA) |

Avoid: Dozens of icons; every platform when audience uses 2–3. Choose 3–5 platforms that match your audience (e.g. B2B: X, LinkedIn; B2C: X, Facebook, WhatsApp).

Share URLs (Intent Links)

Use platform share/intent URLs so users share with one click:

Platform	Share URL pattern
X (Twitter)	INLINECODE0
LinkedIn

https://www.linkedin.com/sharing/share-offsite/?url={url} |
| Facebook | https://www.facebook.com/sharer/sharer.php?u={url} |
| WhatsApp | https://wa.me/?text={url}%20{text} |
| Telegram | https://t.me/share/url?url={url}&text={text} |

Encode url and text with encodeURIComponent(). Use page title or a short pre-written message for text — platform-specific prompts with pre-written messages perform ~4× better than generic icons.

Platform Brand Guidelines (Icons)

Use official brand assets. Minimum sizes and color rules:

Platform	Min size	Colors	Notes
Facebook	16px	Blue #1877F2 or monochrome	No rotation, animation without permission
X (Twitter)

32px | Black or white only | Use current X logo, not deprecated bird |
| LinkedIn | 21px height | Blue #0A66C2 or monochrome | Use "in" bug for icons |
| Instagram | 29×29px | Black, white, or official gradient | Glyph for social icons |

Source icons from official brand resource centers. Outdated or non-compliant icons reduce perceived shareability.

Design & Technical

Item	Guideline
Format	SVG preferred (scalable, small); PNG/WebP with fallback
Performance

Lightweight; avoid heavy share plugins that slow LCP | | Accessibility | aria-label="Share on X"; keyboard accessible | | Mobile | Touch targets ≥44×44px; consider native share API (navigator.share) on mobile |

Native Share API (Mobile)

On supported browsers, navigator.share lets users share via system dialog (includes more apps). Fallback to intent links when unsupported:
