What Are Backlinks in SEO? Simple Guide
Hello guys, welcome back to my blog. Today somebody in my comments asked me a very basic question — what are backlinks in SEO? I get this question a lot, mostly from new bloggers who just started their SEO journey. So I thought let me write a full post about it, in very simple words. In this blog I will tell you what backlinks are, why they matter, the different types, and how I personally try to build them on my own sites. So lets get into it.
What Are Backlinks in SEO, Exactly?
If you ask me in the most simple way, a backlink is just a link from someone else’s website that points to your website. It is also called an inbound link or an incoming link. So if Moz writes a blog post and inside that post they add a link to my site, that is a backlink for me.
Search engines like Google treat backlinks like a vote of confidence. Google’s own guide on links and search says that Google uses links to discover new pages and also to understand how pages on the web are connected to each other. So basically, when other sites link to you, it tells Google that your page might have something useful on it.
I always explain it like this to my readers — think of the internet like a big city, and links are like roads connecting different buildings. If a lot of good roads (backlinks) come to your building (website), more people, and more search engines, will find it easily.
Why Backlinks Matter for SEO
Backlinks are one of the oldest and still one of the biggest ranking factor in SEO. Even after so many Google updates, this has not really changed. Let me tell you why I think backlinks matter so much:
- They act as a trust signal for Google. A page with good backlinks generally looks more trustworthy then a page with none.
- A study by Backlinko on backlinks and rankings found that the number 1 result in Google has about 3.8 times more backlinks then the pages ranked 2 to 10. That is a big difference, if you ask me.
- The same research also found that getting links from many different websites matters a lot. The top ranking page had almost 3 times more referring domains compared to lower positions. So it is not just about total number of links, it is also about how many different sites are linking to you.
- Another interesting fact from that same study, around 95% of all pages on the internet have zero backlinks. This actually surprised me a bit, but it also means even a small number of quality backlinks can put you ahead of most other pages.
- Backlinks also bring you direct referral traffic. If someone reads an article on another blog and clicks my link, that is a real visitor, not just an SEO benefit.
Honestly, I think backlinks are so powerful because they are hard to fake completely. Google has gotten very good over the years at spotting fake or spammy link patterns, which brings me to the next point.
Types of Backlinks You Should Know
Not every backlink is treated the same way by search engines. There are actually a few different types based on a small piece of HTML code called a rel attribute. Google’s own documentation on qualifying outbound links explains this clearly, so I made a simple table below.
| Link Type | What It Means | Common Example |
|---|---|---|
| Dofollow | Normal link, passes SEO value, no special tag | A blogger linking to your guide because they liked it |
| Nofollow | Tells Google not to pass ranking credit | Links in press releases or untrusted sources |
| Sponsored | Used for paid links and ads | A sponsored post or paid mention |
| UGC (User Generated Content) | Used for content added by users | Blog comments, forum posts |
I try to keep this in mind when I do link building or even when I add outbound links on my own blog. As Google says, these tags help search engines understand the real relationship between two sites, whether it is a genuine editorial link, a paid one, or just user content.
What Makes a Backlink “High Quality”?
This is something I really want you guys to understand, because not all backlinks are equal. Getting 100 low quality links is not better then getting 5 really good ones. Based on what I have learned over the years, and also confirmed by guides like Backlinko’s backlink guide, here is what makes a backlink strong:
- Relevance – The linking site should be related to your topic or niche. A cooking blog linking to your SEO article does not carry as much weight as an actual SEO or marketing site linking to it.
- Authority of the source – Sites that have real organic traffic, named authors, and good editorial standards pass more trust then random low quality sites.
- Editorial placement – A link that someone added naturally because they liked your content is much more valuable then a link you paid for or exchanged.
- Anchor text – The clickable text of the link also matters. Natural, descriptive anchor text works better then stuffing exact keywords everywhere. I have actually written a separate post about what anchor text is if you want to read more on this.
- A healthy mix of link types – Having only dofollow exact match links looks unnatural. A real website usually has a mix of dofollow, nofollow, branded, and even some UGC links.
Backlinks vs Internal Links
A lot of beginners get confused between backlinks and internal links, so let me clear this up quickly. Backlinks come from other websites pointing to you. Internal links are links between pages on your own website. Both are important for SEO, but they do different jobs. Internal links help Google understand your site structure, while backlinks help build outside authority and trust for your whole domain.
How I Personally Try to Get Backlinks
I am not going to lie, link building is one of the harder parts of SEO, and it takes real time and effort. But here are some simple things I do on my own blog:
- I write content that is actually useful, so people naturally want to link to it. This is honestly still the best method, even though it sounds basic.
- I check where my competitors are getting their backlinks from, using tools like Ahrefs or Semrush, and then try to reach out to similar sites.
- I try to build genuine relationships with other bloggers in my niche instead of just cold emailing everyone for a link.
- I avoid buying links in bulk from shady networks, because I have seen many sites get penalized for this kind of thing.
- I monitor my backlink profile regularly using free tools like Google Search Console, so I know exactly who is linking to me.
Common Backlink Mistakes to Avoid
I see a lot of new bloggers make the same mistakes when they start with backlinks in SEO, so let me list a few here:
- Buying hundreds of cheap links from link farms, hoping to rank fast. This usually backfires.
- Using the exact same keyword as anchor text every single time, which looks very unnatural to Google.
- Ignoring the quality of the linking site completely, and only caring about the total number of backlinks.
- Never checking their own backlink profile, so they don’t even know if some bad links are hurting them.
- Expecting instant results. Link building is slow, and I think patience is honestly a big part of doing SEO right.
