Link building myths spread because links really do matter, and the details are easy to get wrong. A wrong belief can waste a budget or put a site at risk. Google publishes clear guidance on links, so most myths can be checked.
This guide tests six common claims against Google Search Central and Moz documentation. For each one, you get the myth, what the sources say and what to do instead.
Links still help people and search engines find pages, but more links do not automatically mean better rankings. Domain Authority is a Moz score, not a Google factor. Buying links to rank is link spam under Google’s policies. Use descriptive anchor text, label paid and user-submitted links, and put effort into pages worth linking to.
⚡ Key Takeaways
- Google says links are how it finds new pages, and anchor text tells people and Google what the target page is about.
- Moz states that Domain Authority is not a Google ranking factor and has no effect on search results.
- Google lists buying or selling links for ranking purposes as link spam.
- Mark paid links with rel=”sponsored” and user-generated links with rel=”ugc”.
- Internal links matter too, because they help Google find your other pages.
Link Building Myth 1: More Links Always Mean Higher Rankings
It is tempting to count links and treat the total as a score. Yet Google does not describe links this way. Instead, its guidance says links help it find new pages and give people and search engines context about the page they point to.
In fact, context is the key word. A link placed in a relevant article, written for readers, differs from one dropped into a list of unrelated sites. Google’s spam policies also name excessive link exchanges, such as “link to me and I’ll link to you”, as link spam.
Instead: aim for fewer, relevant links from pages real people read. For a practical list of methods, see these link building techniques that work.
Link Building Myth 2: Domain Authority Is a Google Ranking Factor
Domain Authority, or DA, is a score from Moz. Moz is clear about its status. Its documentation says Domain Authority is not a Google ranking factor and has no effect on the SERPs. It describes DA as a comparative score of a domain’s link profile.
So DA is a handy way to compare sites, but not a target to chase. Even so, a link from a high-DA site is not a guaranteed boost. Check whether the site is relevant to yours and whether real readers visit it.
Instead: use DA as one rough screening tool. Judge a link by relevance and by whether it would send a visitor even if search engines did not exist.
Link Building Myth 3: Exact-Match Anchor Text Is Best
Anchor text is the visible words of a link. Google says it tells people and Google something about the page you link to, and it advises placing it between crawlable <a> elements with an href attribute.
However, keyword-stuffed anchors are a different story. Google’s spam policies list links with optimized anchor text in articles, guest posts or press releases distributed on other sites as an example of link spam.
Instead: so write anchors that describe the destination in plain words. A mix of page names, short phrases and natural wording is what a normal writer would produce.
Link Building Myth 4: Guest Posting Is a Safe Link Shortcut
Guest posting is not banned by Google. Rather, the problem is how it is done. The spam policies flag links with optimized anchor text in guest posts distributed on other sites, and they flag large-scale content campaigns built to place links.
For example, a genuine article, written for a site’s readers, with an author who has real expertise, is a different thing from a template sent to fifty sites. The first earns attention, while the second looks like a scheme.
Instead: pitch fewer sites, write something useful for their audience, and link only where it helps the reader. For a deeper comparison of good and bad practice, read about white hat and black hat link building.
Link Building Myth 5: Buying Links Is a Safe Shortcut
Google defines link spam as creating links to or from a site primarily to manipulate rankings. Its examples include exchanging money for links, exchanging goods or services for links, and sending someone a product in exchange for a link.
In addition, advertorials and native advertising with payment are on the list, when the links pass ranking credit. Google asks site owners to qualify such links. For instance, it recommends rel="sponsored" for ads and paid placements, and rel="ugc" for links in comments and forums. The older nofollow value is still acceptable.
Instead: if you pay for exposure, label the link. If you want links to count, earn them with content and relationships. Before you hire anyone, this guide to building links without triggering penalties lists the warning signs.
Link Building Myth 6: Internal Links Do Not Matter for Link Building
Links from other sites get the attention. Still, your own links do real work. Google says links help it find new pages, and it recommends that important pages be reachable through crawlable links.
Next, when an outside site links to one of your pages, internal links help carry visitors, and crawlers, further into your site. Also, a strong page with no links to your related pages leaves that value stuck.
Instead: after you earn a link, check what the linked page points to next. One way to do it is to use internal links to boost backlink impact.
A Made-Up Example
First, imagine a small accounting firm that buys ten links from a cheap package. The links sit on unrelated blogs with keyword-heavy anchors. Months later, the firm has little to show, and the links match the examples in Google’s spam policies.
Now imagine that the same firm writes one guide to small business tax deadlines and shares it with a local business association. The association links to it, with the anchor “tax deadline guide”. This example is invented. It shows the difference in approach, not a guaranteed result.
A Simple Checklist for Safer Link Building
- Ask whether the link would make sense if search engines did not exist.
- Use descriptive anchor text, not repeated exact-match keywords.
- Mark paid links with rel=”sponsored” and user-submitted links with rel=”ugc”.
- Treat Domain Authority as a rough screen, not a goal.
- Check that your important pages are reachable through normal links.
- Put time into the page being linked to before you seek links.
Conclusion
In short, most link building myths come from treating links as a count. The sources tell a simpler story: relevant links help, spam does not, and the page being linked to still has to deserve attention.
Therefore, pick one claim from this list that you have believed, and check your own links against it this week. Teams that prefer to hand the work to specialists can compare options for link building services.
Frequently Asked Questions About Link Building Myths
Is link building still worth doing?
Yes, when it is done honestly. Google says links help it discover pages and understand what they are about. The risk comes from schemes made to manipulate rankings, which its spam policies cover.
Does Domain Authority affect Google rankings?
No. Moz, which created the score, says Domain Authority is not a Google ranking factor and has no effect on search results.
Should I use nofollow on every external link?
No. Google says to use nofollow only when you do not trust the source, not for every external link. For paid links, it prefers sponsored. For user-generated links, it recommends ugc.
Is guest posting against Google’s rules?
Not by itself. Google’s spam policies target manipulative patterns, such as optimized anchor text in guest posts distributed on other sites. Genuine articles for a site’s audience are a different matter.
Can paid links hurt my site?
They can, if they pass ranking credit. Google counts buying or selling links for ranking purposes as link spam, and sites that break its policies may rank lower or not appear in results.
