External links are votes for your site from other websites, and search engines use them to decide how trustworthy and relevant you are

When another site links to yours, Google and other search engines treat it as a signal that your content is worth reading. But not all links carry the same weight. A link from a site that already ranks well for topics related to yours matters more than a link from a random blog. A link placed naturally in the middle of an article matters more than one buried in a footer. And a link that uses relevant words as the clickable text matters more than one that just says "click here."

Building external links takes time and strategy. You cannot buy your way to credibility, and search engines penalize sites that try. Instead, you build links by creating content people actually want to link to, then reaching out to the right people and giving them a reason to share it.

Key Takeaways

  • Links from established sites in your industry carry far more weight than links from new or unrelated sites, so focus on quality over quantity.
  • The words used in a link (called anchor text) should describe what readers will find, not generic phrases like "click here" or your exact business name.
  • Create something worth linking to first — original research, detailed guides, tools, or data — before you ask anyone to link to it.
  • Reach out to site owners and journalists directly with a specific reason why their audience would care about your content, not a generic link request.
  • Monitor your links regularly using free tools like Google Search Console to catch broken links and understand which sites send you the most valuable traffic.

Create content that people want to link to naturally

The foundation of any link-building strategy is having something worth linking to. Sites link to content that solves a problem, answers a question their audience is asking, or provides data or insight they cannot find elsewhere. A generic blog post about your industry will not earn links. Original research, detailed how-to guides, tools, or comprehensive data will.

Think about what your competitors are getting linked to. Use a tool like Ahrefs (paid, with a free trial) or Moz (paid) to see which of their pages have the most external links. Look for patterns. Are they getting links for original studies? For tools? For guides that go deeper than anything else online? Start there. If your competitors have published original research on a topic your industry cares about, consider whether you can do something similar or go further.

Your content does not have to be flashy. It has to be useful and specific. A guide titled "How to Reduce Shipping Costs for Small E-Commerce Stores" will earn more links than "Tips for Running an Online Store" because it solves a concrete problem for a concrete audience.

Understand what makes a link valuable to search engines

Not every link helps your site equally. Search engines look at several factors when deciding how much weight to give a link. The most important is the authority of the site linking to you — a link from a site that already ranks well and has many quality links pointing to it is worth far more than a link from a brand-new site. A link from a site in your industry or related to your topic is worth more than a link from a completely unrelated site.

The anchor text — the words someone clicks on — also matters. If a site links to your article about dog training using the words "dog training tips," that is more valuable than if they link using "this article" or your business name. The anchor text tells search engines what your page is about. Relevant anchor text reinforces that connection.

The context around the link matters too. A link placed naturally in the middle of a paragraph, where it makes sense to the reader, signals more trust than a link in a footer or sidebar. Search engines assume that if an editor thought your content was relevant enough to link to in the body of their article, it must be genuinely useful.

Find sites and people worth reaching out to

Once you have content worth linking to, the next step is finding the right people to contact. You are looking for sites that your target audience already reads, sites that cover topics related to yours, and sites that have the authority to help your search rankings.

Start with a Google search for the topics you cover. Look at the top-ranking sites and note which ones might link to you. Are there industry blogs, news sites, or resource pages that cover your field? Check their "about" or "contact" pages to find the right person to reach out to — usually an editor or the site owner.

Look for broken links on relevant sites. If a site links to a resource that no longer exists, you can offer your content as a replacement. Tools like Check My Links (a free browser extension) let you scan a page for broken links. This is one of the most effective ways to earn links because you are solving a problem for the site owner, not just asking for a favor.

Search for resource pages in your industry. Many sites maintain lists of useful tools, guides, or references. If your content fits, reach out and ask to be included. These pages are often updated regularly and can send steady traffic over time.

Reach out with a specific, personal reason to link

Generic link requests do not work. Site owners and editors receive dozens of them every week. Your outreach has to be personal and specific. Show that you have actually read their site and understand their audience.

Start by mentioning a specific article or resource they published. Explain why your content is relevant to their readers and how it adds to the conversation they are already having. If you are offering a replacement for a broken link, mention that directly. If you have original data or research that supports a point they made, reference it.

Keep the message short. Three or four sentences is enough. Include a link to your content and make it easy for them to see why it matters. Do not ask them to link to your homepage or your main service page — link to the specific piece of content that is relevant to their audience.

Here is what a real outreach message might look like: "Hi [Name], I read your guide on reducing warehouse costs and noticed you referenced the 2019 logistics report. We just published original research on this topic from 2024 that includes data on automation ROI. I thought your readers might find the updated numbers useful. [Link]" That is specific, shows you have done your homework, and gives them a clear reason to consider linking.

Build relationships with journalists and industry influencers

One of the most reliable sources of high-quality links is journalists and industry writers who cover your field. When they write about topics related to your business, they often link to relevant sources. If they know about your work and trust it, you are more likely to be included.

Start by following journalists and writers who cover your industry. Read their work. Share it when it is good. Comment thoughtfully on their articles. Over time, when you have something genuinely newsworthy or useful, they will be more likely to link to it because they already know who you are.

When you have news or research worth sharing, send it to relevant journalists directly. A press release about a new tool, study, or insight can earn links from news sites and industry publications. Make sure what you are sharing is actually news — not just a promotion for your business, but something that affects the industry or answers a question people are asking.

Monitor your links and fix problems

Once you start earning links, you need to know where they are coming from and whether they are still working. Google Search Console (free, requires a Google account) shows you which sites link to yours and how often Google finds them. Check it regularly to understand which links are driving the most value.

Look for broken links pointing to your site. If a page you created gets deleted or moved, the link breaks and search engines stop counting it as a vote for you. Set up redirects so that old links still work. If you notice a site linking to a page that no longer exists, reach out and ask them to update the link to your new page.

Watch for low-quality links pointing to your site. If you notice links from spam sites or sites completely unrelated to your industry, you can disavow them in Google Search Console. This tells Google to ignore those links when calculating your rankings. Do not disavow links from legitimate sites just because they are not from your top choice — only disavow links that look like spam or that you believe were placed without editorial judgment.

Avoid tactics that search engines penalize

Some link-building tactics might seem faster but will damage your site's rankings if search engines catch them. Buying links, trading links with unrelated sites just to inflate numbers, and using automated tools to post links across the web are all against Google's guidelines. Sites caught doing this face ranking penalties that can take months to recover from.

Avoid link schemes where you agree to link to someone else's site in exchange for them linking to yours, especially if the sites are unrelated to your industry. Avoid paying for links or using services that promise to build links for you quickly. Avoid posting the same link across dozens of forums or comment sections.

The safest approach is the slowest one: create genuinely useful content, reach out to relevant people with a real reason to link, and build relationships over time. This takes longer, but the links you earn this way are stable and actually help your search rankings.

Frequently Asked Questions

How many external links do I need to rank well?

There is no magic number. Search engines care more about the quality and relevance of your links than the quantity. A site with 50 links from established, relevant sites will rank better than a site with 500 links from random, low-authority sites. Focus on earning links from sites your audience already trusts.

Does it matter if a link is "nofollow" or "dofollow"?

Dofollow links pass ranking value to your site; nofollow links do not. However, nofollow links still matter because they can drive traffic and signal to search engines that your content is worth reading. Do not ignore nofollow links — just prioritize dofollow links from relevant, authoritative sites.

How long does it take to see results from link building?

Search engines typically discover and process new links within a few weeks, but it can take months to see a noticeable change in your rankings. Link building is a long-term strategy. Consistency matters more than speed.

Can I ask people to link to me on social media?

Social media links do not directly affect search rankings because they are usually nofollow links. However, sharing your content on social media can help it reach journalists, bloggers, and site owners who might link to it. Use social media to amplify your content, not as a direct ranking tactic.

What should I do if a site links to me with bad anchor text?

You can reach out politely and ask them to update the anchor text to something more descriptive. Many site owners are happy to make small changes if you explain why it helps both of you. If they do not respond or refuse, the link still helps you — it is just not as valuable as it could be.
