  11. Take Action: Build Your Strategic Backlink Portfolio

Backlinks are links from one website to another, acting as “votes of confidence” in the eyes of search engines. Google’s algorithm treats high-quality backlinks as signals that your content is valuable, trustworthy, and worth ranking higher in search results.

However, the type of backlink determines its value. A single high-quality editorial link from a respected publication can outweigh dozens of low-quality directory links. Understanding these distinctions is what separates successful SEO campaigns from ineffective ones.

The fundamental distinction in types of backlinks starts with how they pass link equity.

Dofollow links are the gold standard of backlinks. They pass “link juice” directly to your site, signaling to search engines that the linking site vouches for your content’s quality and relevance.

Characteristics of dofollow links:

  • No special HTML attributes restricting crawling
  • Pass PageRank and authority to your site
  • Directly impact your search engine rankings
  • Most valuable for SEO purposes

HTML example:

<a href="https://yoursite.com">Great resource here</a>

Nofollow links include a rel="nofollow" attribute that tells search engines not to pass ranking credit to the linked site. While they don’t directly boost rankings, they still provide value through referral traffic and brand exposure.

HTML example:

<a href="https://yoursite.com" rel="nofollow">Check this out</a>

Why nofollow links still matter:

  • Drive referral traffic to your site
  • Increase brand awareness and visibility
  • Create natural link profile diversity
  • Can lead to dofollow links when people discover your content

Optimal ratio: A healthy backlink profile typically contains 80-90% dofollow links and 10-20% nofollow links.

Editorial links are the most valuable type of backlink because they’re earned naturally through content quality and relevance. These links appear within the main content of articles, blog posts, or resource pages where the author genuinely recommends your content.

  • Contextual relevance: Placed within relevant content discussing your topic
  • Natural placement: Integrated seamlessly into the author’s narrative
  • High trust signals: Demonstrate that real people find your content valuable
  • Strong ranking impact: Google weights these links heavily in its algorithm
  • A tech blogger linking to your software comparison guide within a product review
  • A journalist citing your industry research in a news article
  • An academic paper referencing your study or data
  • A resource roundup featuring your comprehensive guide
  1. Create linkable assets: Original research, comprehensive guides, industry reports
  2. Develop newsworthy content: Trend analyses, expert predictions, survey results
  3. Build relationships with journalists: Use HARO, follow industry reporters on social media
  4. Monitor brand mentions: Convert unlinked mentions into linked citations

3. Guest Post Backlinks

Guest posting involves writing content for other websites in exchange for a backlink to your site. When done strategically, guest post links can be highly effective for SEO.

High-Quality Guest Post Links

Characteristics of valuable guest post backlinks:

  • Published on topically relevant, high-authority sites
  • Placed within contextually relevant content
  • Link to genuinely helpful resources on your site
  • Come from sites with engaged readerships
  • Are part of comprehensive, valuable articles

Red Flags for Guest Post Links

  • Sites that accept any content regardless of quality
  • Obvious link exchanges or reciprocal arrangements
  • Generic author bios with exact-match anchor text
  • Low-quality sites with thin content
  • Overuse of commercial anchor text

Best practices for guest posting:

  • Research the target site’s audience and content style
  • Pitch unique, valuable topic ideas
  • Write genuinely helpful content, not promotional pieces
  • Use natural anchor text variations
  • Build relationships, not just one-off transactions

4. Resource Page Links

Resource links appear on curated lists of helpful tools, guides, or industry resources. These pages specifically exist to recommend valuable content to visitors, making them highly relevant for SEO.

Types of Resource Pages

  • Industry resource directories: Comprehensive lists of tools and guides
  • “Best of” roundups: Curated collections of top resources
  • Educational resource pages: Academic or training-focused link collections
  • Tool and software directories: Categorized lists of industry tools
  • Government and association resources: Official resource compilations
  • High relevance: Your content is grouped with other quality resources
  • Targeted traffic: Visitors are actively seeking helpful resources
  • Authority by association: Being listed alongside established resources builds credibility
  • Long-term value: Resource pages often remain stable for months or years

How to Get Resource Page Links

  1. Find relevant resource pages: Use search operators like "your industry" + resources
  2. Analyze existing listings: Ensure your content meets the quality standard
  3. Craft personalized outreach: Explain how your resource adds unique value
  4. Follow submission guidelines: Many resource pages have specific requirements
  5. Maintain relationships: Thank site owners and offer future value

Social signals from platforms like Facebook, Twitter, LinkedIn, and Instagram are typically nofollow but still contribute to your overall digital footprint and can lead to valuable editorial links.

  • Content discovery: Social shares help content reach new audiences
  • Referral traffic: Direct clicks from social platforms
  • Brand awareness: Increased visibility in your industry
  • Link earning potential: Social exposure can lead to natural editorial links
  • Local SEO benefits: Particularly important for local businesses
  • Share valuable content consistently: Focus on helpful, shareable resources
  • Engage with industry influencers: Build relationships that can lead to amplification
  • Optimize social profiles: Include your website link in all profile sections
  • Use platform-specific strategies: Tailor content format to each platform’s strengths
  • Monitor social mentions: Engage with people discussing your brand or content

Directory links come from business listings, industry directories, and citation sites. Quality varies dramatically in this category, making it crucial to focus on authoritative, relevant directories.

High-Value Directory Types

Local directories:

  • Google My Business
  • Bing Places
  • Apple Maps Connect
  • Local chamber of commerce listings

Industry-specific directories:

General high-authority directories:

  • Better Business Bureau
  • Yelp (for applicable businesses)
  • Industry-specific review sites
  • Maintain NAP consistency: Name, Address, Phone number must match across all listings
  • Choose quality over quantity: 10 high-quality directories beat 100 low-quality ones
  • Complete profiles thoroughly: Fill out all available fields and categories
  • Monitor and maintain listings: Keep information current and respond to reviews
  • Avoid link farms: Stay away from directories that exist solely for SEO manipulation

Community links come from forums, discussion boards, Q&A sites, and niche communities. While often nofollow, they can drive targeted traffic and establish thought leadership.

Valuable Community Platforms

  • Industry-specific forums: Niche communities in your field
  • Reddit: Relevant subreddits for your industry
  • Quora: Answer questions related to your expertise
  • LinkedIn groups: Professional communities and discussions
  • Stack Overflow: For technical and development topics
  1. Provide genuine value first: Answer questions and share insights before promoting content
  2. Follow community guidelines: Each platform has specific rules about self-promotion
  3. Build reputation gradually: Establish credibility before sharing your own links
  4. Focus on helping: Share your content only when it genuinely solves problems
  5. Engage consistently: Regular participation builds trust and authority

Press release links come from news sites, press release distribution services, and media coverage. Quality varies significantly based on the publication and newsworthiness of your content.

  • Earned media coverage: Journalists writing about your company or research
  • Industry publication features: Trade magazines and specialized news sites
  • Local news coverage: Regional newspapers and news websites
  • Podcast mentions: Links from podcast show notes and transcripts
  • Generic PR distribution: Mass-distributed releases with little editorial oversight
  • Low-quality news sites: Sites that publish any press release without editorial review
  • Over-optimization: Press releases stuffed with exact-match anchor text
  • Fake news sites: Low-authority sites created primarily for link building

Reciprocal links involve two sites linking to each other. While not inherently bad, excessive reciprocal linking can trigger Google penalties.

  • Natural business relationships: Partners, suppliers, or complementary businesses
  • Limited scope: Small number of relevant, valuable exchanges
  • Contextual relevance: Links make sense within the content context
  • Varied anchor text: Natural language rather than exact-match keywords
  • Large-scale link exchanges: Systematic trading of links with many sites
  • Irrelevant partnerships: Links between unrelated industries or topics
  • Link page networks: Dedicated “links” pages existing solely for exchanges
  • Automated exchanges: Software-driven link trading systems

Paid links are purchased directly or through sponsored content arrangements. Google’s guidelines require these links to be marked with rel="sponsored" or rel="nofollow" attributes.

Sponsored content:

  • Advertorials and sponsored articles
  • Influencer partnerships and collaborations
  • Product reviews and endorsements
  • Branded content partnerships

Direct link purchases:

  • Buying placement on relevant websites
  • Directory submission fees
  • Premium listing upgrades
  • Link insertion services
  1. Use proper attributes: Mark paid links with rel="sponsored"
  2. Focus on value: Ensure sponsored content provides genuine value to readers
  3. Choose relevant sites: Only work with sites in your industry or niche
  4. Avoid link schemes: Don’t participate in large-scale paid link networks
  5. Diversify your strategy: Paid links should supplement, not replace, earned links

Understanding good vs bad backlinks is crucial for building a healthy link profile that boosts rather than hurts your SEO performance.

The guest post trap: Many SEOs focus exclusively on guest posting, creating unnatural link profiles that lack diversity. Search engines prefer varied link types that reflect natural online relationships.

Directory submission obsession: Submitting to hundreds of low-quality directories creates more risk than reward. Focus on 10-20 high-quality, relevant directories instead.

Sidebar and footer links: Links placed in less prominent positions carry less weight than editorial links within main content. Prioritize content-based link placement.

Irrelevant link contexts: A link from a cooking blog to a B2B software company provides little SEO value due to topical irrelevance.

Anchor Text Over-Optimization

Exact-match anchor text abuse: Using the same keyword-rich anchor text across multiple links signals manipulation to search engines. Vary your anchor text naturally.

Unnatural link language: Phrases like “click here for the best SEO services” sound promotional rather than editorial.

Video and multimedia links: Links from video descriptions, podcast show notes, and multimedia content are becoming increasingly valuable as content consumption shifts.

AI-generated content citations: As AI content becomes more prevalent, links from high-quality AI-generated resources may gain importance.

Voice search and featured snippet links: Content that appears in voice search results and featured snippets may generate new types of valuable backlinks.

Algorithm Evolution Impact

E-A-T emphasis: Google’s focus on Experience, Expertise, Authoritativeness, and Trustworthiness makes editorial links from authoritative sources more valuable than ever.

Context and relevance prioritization: Search engines are getting better at understanding content context, making topically relevant links more important than high-authority but irrelevant ones.

Link quality over quantity: The trend toward quality continues, with search engines becoming more sophisticated at identifying and discounting low-quality link schemes.

Frequently Asked Questions

Dofollow links pass ranking authority from the linking site to your site, directly impacting your search engine rankings. Nofollow links include a rel="nofollow" attribute that tells search engines not to pass ranking credit, but they still provide referral traffic and brand exposure value.

Focus on 4-5 different link types to create a natural, diverse backlink profile. Prioritize editorial links (40-50%), resource/directory links (20-30%), guest post links (15-25%), and social/community links (10-15%) for optimal results.

Paid backlinks can be valuable when they’re high-quality, relevant, and properly marked with rel="sponsored" attributes. However, focus primarily on earning links through exceptional content and relationships rather than purchasing them.

Editorial links from high-authority sites typically provide the fastest ranking improvements because they carry the most weight with search engines. However, building a diverse portfolio of link types creates more sustainable long-term results.

High-quality backlinks come from authoritative, relevant websites with strong editorial standards. Look for sites with consistent content publication, engaged audiences, strong social presence, and topical relevance to your industry.

The biggest mistake is focusing on quantity over quality. A few high-quality editorial links from relevant, authoritative sites will outperform hundreds of low-quality directory or forum links every time.

Understanding types of backlinks is just the beginning. The real SEO success comes from implementing a strategic mix of high-quality link types that align with your business goals and target audience.

Start by auditing your current backlink profile to identify gaps and opportunities. Focus 70% of your efforts on earning editorial links through exceptional content and relationship building, while using the remaining 30% to build supporting links through guest posts, directories, and community engagement.

Remember: the best backlink strategy prioritizes quality over quantity and relevance over authority. A smaller portfolio of highly relevant, high-quality links will always outperform a large collection of irrelevant or low-quality ones.
