Internal Links vs. External Backlinks: What’s the Difference?
If your website isn’t ranking, it’s rarely just “bad luck.” More often, it’s a linking problem. You either don’t have enough authority pointing in, or you’re not distributing the authority you already have.
In this guide, you’ll learn the clear difference between internal links and external backlinks, why both matter, and how to use them strategically to grow traffic and leads. If you’re investing in Gilbert search engine optimization, understanding this distinction can save you time, money, and frustration.
Many businesses throw money at SEO services without knowing whether their site structure or backlink profile is the real issue. Agencies like Leads by Vinny often emphasize that link strategy isn’t optional, it’s foundational.
Let’s break it down in plain English.
What Are Internal Links?
Internal links are links that connect one page of your website to another page on the same website.
Simple.
If you link from your homepage to your blog, or from a blog post to a service page, that’s an internal link.
Why Internal Links Matter
Internal links:
Help search engines understand your site structure
Distribute authority (also called “link equity”)
Keep visitors on your site longer
Guide users toward conversions
Think of your website like a city. Internal links are the roads connecting neighborhoods. Without them, visitors get lost. Search engines do too.
Example
If you run a local landscaping business, you might link from a blog post about lawn care tips to your lawn installation service page. That signals relevance and strengthens the service page.
The key is intention. Random linking doesn’t work. Strategic linking does.
What Are External Backlinks?
External backlinks (often just called “backlinks”) are links from other websites pointing to your website.
These are the heavy hitters.
When another website links to you, it’s essentially casting a vote of confidence. The more high-quality votes you get, the more authority your site builds in the eyes of search engines.
Why Backlinks Matter
Backlinks:
Build domain authority
Improve rankings for competitive keywords
Increase referral traffic
Establish credibility
But not all backlinks are equal.
A link from a respected industry publication carries more weight than a random directory. Quality beats quantity every time.
The Core Difference
Here’s the simplest way to think about it:
Internal links control structure.
External backlinks build authority.
Internal links are completely under your control. You decide where they go and how they’re used.
Backlinks, on the other hand, must be earned.
You can influence them through:
Guest blogging
PR outreach
Partnerships
Creating link-worthy content
But you don’t directly control them.
Both work together. Without backlinks, your site lacks power. Without internal links, you waste that power.
How They Work Together
Imagine you earn one strong backlink to a blog post.
If that blog post doesn’t internally link to your core service pages, you’ve trapped the authority on one page.
That’s a mistake.
Smart SEO strategy uses internal links to funnel authority from high-performing pages to revenue-driving pages.
This is where many small businesses fall short. They focus on getting backlinks but ignore internal architecture. Or they obsess over site structure without building external authority.
You need both.
Case Study: From Stagnant to Scaling
A small home services company struggled to rank despite publishing regular blog content. They had decent traffic, but service pages barely converted.
After an audit, two issues stood out:
Almost no internal links pointing to core services
Very few quality backlinks
The fix was simple but deliberate.
They:
Added contextual internal links from blog posts to service pages
Secured five strong local backlinks through partnerships and guest posts
Within four months:
Service page rankings improved
Organic traffic increased by 38%
Leads nearly doubled
Nothing magical. Just structured authority and smart distribution.
Practical Action Steps
If you want results, here’s what to do next:
For Internal Links
Link from high-traffic pages to important service pages
Use descriptive anchor text (not “click here”)
Avoid overlinking unnecessarily
Audit orphan pages with no inbound links
For Backlinks
Create data-driven or original content
Build relationships in your industry
Pitch guest posts to relevant websites
Focus on authority, not volume
SEO is not about tricks. It’s about structure and credibility.
Final Takeaway
Internal links help search engines understand your website. External backlinks help search engines trust it. Ignore either one, and you limit your growth.
If you’re serious about improving rankings and turning traffic into revenue, audit both today and fix the weak side first. Then, build authority and contact us to help you win.
