A sidebar link is a hyperlink placed in the sidebar section of a webpage, typically appearing on every page of a website. Sidebars commonly contain navigation menus, recent posts, categories, blogrolls, or widget areas where links can be placed.

Placement and Visibility#

Sidebar links appear in the vertical column alongside main content:

  • Usually on the left or right side of pages
  • Often repeated across multiple or all pages
  • May contain navigation, resources, or promotional links
  • Commonly found in blog and content site layouts

Blogroll links: Lists of recommended sites Widget links: Links in sidebar widgets or plugins Resource links: Links to tools or related resources Sponsor links: Paid promotional placements Navigation links: Internal site navigation


Google's Treatment#

Google's algorithms have evolved to understand sidebar links:

Reduced weight: Sidebar links often carry less SEO value than in-content links Sitewide consideration: Google may count multiple instances as a single link Context evaluation: Relevance of the sidebar to main content matters User experience signals: How users interact with sidebar links affects value

The Reasonable Surfer Model#

Google's patent describes evaluating links based on likelihood of being clicked:

  • Sidebar links may receive lower click probability scores
  • Position and prominence affect assigned value
  • Links buried in sidebars carry less weight than prominent ones

Key Differences#

| Aspect | Sidebar Links | Contextual Links | |--------|---------------|------------------| | Placement | Side column | Within content | | Editorial context | Limited | High | | Click probability | Lower | Higher | | SEO value | Reduced | Higher | | Natural occurrence | Common | Most valuable |

Why Context Matters#

Contextual links within content:

  • Have clear topical relevance
  • Are more likely to be clicked
  • Suggest editorial endorsement
  • Pass more link equity

Legitimate Uses#

Resource lists: Curated industry resources Partner links: Legitimate business partnerships Navigation: Helping users find related content Blogrolls: Editorial recommendations (less common now)

Natural sidebar links typically:

  • Come from genuine relationships
  • Serve user needs
  • Aren't paid placements
  • Appear on relevant sites

Potential Problems#

Sitewide links: Creating hundreds of links from one domain Link schemes: Paid sidebar placements for SEO Widget abuse: Links embedded in free widgets Irrelevant sites: Sidebar links from unrelated niches

Google's Guidelines#

Google has specifically addressed sidebar links:

  • Widget links should use nofollow
  • Paid sidebar placements need disclosure
  • Manipulative sidebar link schemes violate guidelines
  • Excessive sitewide linking appears unnatural

Prefer contextual: Ask for in-content placement instead Check relevance: Ensure the site is topically related Verify quality: Assess the linking site's authority Consider nofollow: May be more appropriate for sidebar placement

Use nofollow: For paid or uncertain links Limit quantity: Don't create excessive outbound sidebar links Stay relevant: Only link to related, quality resources Review regularly: Audit sidebar links periodically


Declining Importance#

Sidebar links have become less important because:

  • Search engines devalue them
  • Users often ignore sidebars (banner blindness)
  • Mobile-first indexing reduces sidebar visibility
  • Contextual links are clearly more valuable

When They Still Matter#

Sidebar links can still provide value:

  • Referral traffic from relevant sites
  • Brand visibility
  • Relationship building
  • User navigation (internal links)

Summary#

Sidebar links are hyperlinks placed in webpage sidebars:

Key characteristics:

  • Appear in side columns
  • Often sitewide
  • Lower SEO value than contextual links
  • May be discounted by Google

Best practices:

  • Prefer contextual links when possible
  • Use nofollow for paid placements
  • Focus on relevance and quality
  • Don't rely on sidebar links for SEO

While sidebar links aren't inherently harmful, they're less valuable than editorial contextual links and should be approached carefully in link building.
