What is backlink in SEO?

A backlink is a link from one website directing to another website. In SEO, backlinks are important for ranking websites in search engines like Google. The more quality backlinks a website has, the higher it tends to rank in search results pages (SERPs).

Why Backlinks Matter for SEO

Backlinks serve as votes of confidence. When a website links to your content, it indicates:

• Your content offers value worth linking to
• Your site is credible and trustworthy
• Search engines can crawl new sites discovering more quality content

Google’s algorithm interprets backlinks as endorsements. More backlinks signals your contentpopularity and authority on a given topic.

While quantity of backlinks matter, the quality and relevance of each backlink affects SEO rankings more.

How to Get Quality Backlinks

Here are effective white hat tactics to earn authoritative backlinks:

1. Create Compelling, Useful Content

• Focus on creating long-form content like guides, research reports, and tutorials
• Answer audience questions and provide unique insights
• Promote content on social media driving referral traffic

Google will crawl links back to truly valuable content that engages visitors.

2. Guest Post Outreach

• Identify websites accepting contributor posts related to your niche
• Pitch relevant post ideas providing value for their audience
• Secure backlinks within contributed posts along with exposure to new readers

Strive for strong web 2.0 backlinks from reputable, high-authority domains.

3. Link Insert Outreach

• Curate a list of reputable websites you’d like to earn backlinks from
• Contact them asking to insert a link to relevant content from your site within existing posts
• Offer to reciprocate the favor on your site

This content enhancement approach builds relationships with webmasters.

4. Broken Link Building

• Leverage tools identifying broken external links on niche webpages
• Offer site owners replacement links to your relevant content fixing their dead links
• Provide value helping them enhance user experience

Most webmasters readily accept qualified link swap proposals.

5 Remodel and Relaunch Old Content

• Audit your site identifying outdated posts still gaining some traction
• Freshen up the content with new stats, studies, and perspectives
• Repurpose as new resource guides, case studies, or analyses

Google favors recently updated evergreen content.

What is a Good Backlink vs Bad Backlink?

Here are signals of quality backlinks:

Good Backlink Characteristics

• Contextually relevant anchor text and content
• Located in naturally embedded body content
• Hosted on reputable, high-authority domains with low spam scores
• Part of a diversified link profile from a mix of domains

Bad Backlink Characteristics

• Irrelevant or manipulative anchor text like “click here”
• Found primarily in footers or site sidebars
• Hosted on low quality, low authority sites
• Repeated anchor text links from a group of sites (“paid links”)

A few spammy backlinks likely won’t hurt you. But an entirely manipulative link building strategy risks Google penalties.

How to Disavow Bad Backlinks

If your site already has problematic backlinks, Google recommends formally disavowing them through Search Console:

Step 1) Download your site’s backlink report under Search Traffic in Google Search Console.

Step 2) Review link data for sketchy patterns like identical anchor text links.

Step 3) Select disreputable domains to disavow under “Disavow Links” tool.

Step 4) Check reports in a few weeks ensuring disavowed links show as “No Followed.”

Use disavows conservatively:

• Disavow entirely spammy domain links (eg. sketchy directories)
• Don’t disavow a few bad links from otherwise reputable sites

Conclusion Key Takeaways

• Backlinks serve as credibility and authority signals for search engine rankings
• Focus on getting editorial style niche backlinks naturally rather than risking penalties
• Continuously produce high quality content worthy of referencing and backlinking to
• Monitor your site’s backlink profile avoiding spam patterns

Frequently Asked Questions

   Do follow backlinks pass link juice and equity to your site for SEO rankings. Nofollow backlinks instruct search engines NOT to factor into rankings calculations.

3. What is an external backlink?
   An external backlink comes from a separate domain pointing back to pages on your root domain. For example, if Site A links to Site B, that link on Site A pointing to Site B counts as an external backlink in Site B’s backlink profile report.

   While nofollow links technically don’t boost rankings directly, they CAN provide search visibility benefits related to:

   Discovery of new quality link prospects
   So nofollowed links aren’t entirely useless for SEO…
