However, not all anchor text is created equal. A “natural anchor text profile” is essential for long-term SEO success. This guide will define what constitutes a natural anchor text distribution, explain the significant risks of over-optimisation, and provide a practical, step-by-step approach to auditing and rebalancing your site’s link profile to ensure it remains healthy and effective.
What is Anchor Text? A Foundation for Understanding
At its core, anchor text is the descriptive, clickable text that forms a hyperlink. For example, in the sentence “Learn more about SEO best practices“, “SEO best practices” is the anchor text. Search engines like Google use this text as a signal to understand the topic and relevance of the page being linked to.
When a search engine crawls a page and encounters a hyperlink, it reads the anchor text to gain insight into the destination content. If many links point to a page with similar anchor text, it suggests to the search engine that the linked page is highly relevant to that specific keyword or phrase. This mechanism is powerful, but it can also be misused, leading to what’s known as over-optimisation.
Understanding a Natural Anchor Text Profile
A natural anchor text profile is characterised by diversity and relevance, mirroring how links would organically occur across the web. It’s not about adhering to rigid percentages but rather ensuring your anchor text distribution looks authentic and serves both users and search engines effectively.
What is Anchor Text Distribution?
Anchor text distribution refers to the variety and proportion of different types of anchor text pointing to a specific page or an entire website. A healthy distribution includes a mix of various anchor text types, reflecting a natural link-building process rather than a manipulative one.
Types of Anchor Text and Their Role
To understand a natural profile, it’s important to know the different categories of anchor text:
- Branded Anchor Text: This uses your brand name or website name as the anchor. For example, “Learn more at Your Company Name“. This is highly natural, as people often link to brands by name.
- Naked URL Anchor Text: This is simply the raw URL of the linked page. For instance, “https://yourcompany.com/blog“. This is also very natural, especially in citations or casual mentions.
- Generic Anchor Text: These are non-descriptive phrases like “click here,” “read more,” “learn more,” or “this page.” While common, they offer little contextual value to search engines.
- Exact Match Anchor Text: This uses the precise target keyword of the linked page. For example, if a page is optimised for “best coffee beans,” the exact match anchor text would be “best coffee beans“. This type is powerful for relevance but carries the highest risk of over-optimisation if overused.
- Partial Match Anchor Text: This includes the target keyword along with other words. For example, “discover the best coffee beans for brewing” or “our guide to coffee beans“. This offers relevance while appearing more natural than exact match.
- Image Anchor Text: When an image is linked, the anchor text is derived from the image’s alt text attribute. This highlights the importance of descriptive alt text for SEO.
What Constitutes a “Natural” Profile?
A natural anchor text profile for external links (backlinks) typically shows a high percentage of branded and naked URL anchors, followed by generic and partial match anchors. Exact match anchor text should generally be a smaller percentage, as it’s less common for external sites to link to you using your precise target keyword naturally.
For internal links, you have more control. While you can use more keyword-rich anchor text for internal links to help search engines understand your site structure and pass link equity, it’s still wise to vary your internal link anchor text distribution. Over-optimising internal links can also lead to issues, though typically less severe than with external links. The key is always contextual relevance and a focus on user experience. The anchor text should accurately describe what the user will find on the linked page.
The Risks of Anchor Text Over-Optimisation
While using keyword-rich anchor text might seem like a direct path to higher rankings, an excessive or unnatural use of exact match anchor text can lead to severe negative consequences. This is known as anchor text over-optimisation.
What is Over-Optimisation?
Over-optimisation occurs when your backlink profile, particularly the external links pointing to your site, shows an unnaturally high proportion of exact match or overly keyword-rich anchor text. Search engines view this as an attempt to manipulate rankings rather than a genuine reflection of a site’s authority and relevance.
Imagine a scenario where 70% of all backlinks to your page about “blue widgets” use the exact anchor text “blue widgets.” This pattern is highly unlikely to occur naturally. It signals to search engines that someone is actively trying to boost rankings for that specific keyword, often through artificial or low-quality link-building methods.
Negative Impacts on SEO
The primary risk of anchor text over-optimisation stems from Google’s efforts to combat web spam and ensure fair search results. The most notable impact came with the Google Penguin algorithm updates, which specifically targeted manipulative link-building practices.
If your site is flagged for an over-optimised anchor text distribution, you could face:
- Algorithm Penalties: Your site’s rankings for the targeted keywords (and potentially others) could drop significantly. This is an automated response from Google’s algorithms.
- Manual Penalties: In more severe cases, a Google reviewer might issue a manual action against your site, leading to a drastic loss of search visibility. You would then need to address the issue and submit a reconsideration request.
- Devaluation of Links: Even if not penalised, over-optimised links may simply be devalued by search engines, meaning they pass little to no SEO benefit.
- Loss of Organic Traffic: A drop in rankings directly translates to a reduction in organic search traffic, impacting your business goals.
Search engines penalise over-optimisation because their goal is to provide the most relevant and high-quality results to users. Manipulative link building, including unnatural anchor text distribution, undermines this goal by attempting to artificially inflate a site’s perceived relevance. By prioritising genuine relevance and user experience, search engines aim to deliver a better search experience.
Auditing Your Anchor Text Profile: A Step-by-Step Guide
Understanding your current anchor text distribution is the first critical step toward ensuring a healthy link profile and avoiding over-optimisation. This audit process applies to both external and internal links, though the focus for over-optimisation is primarily on external backlinks.
Step 1: Gather Your Backlink Data
To begin, you’ll need access to your backlink data. Several reputable SEO tools can provide this information:
- Ahrefs: Offers a comprehensive “Anchors” report within its Site Explorer, showing all anchor texts pointing to your domain or a specific URL, along with the number of referring domains and links.
- SEMrush: Provides a similar “Anchors” report under its Backlink Analytics tool, detailing anchor text variations and their usage.
- Moz Link Explorer: Also includes an “Anchor Text” section that lists the most common anchor texts pointing to your site.
- Google Search Console: While less detailed than paid tools, Google Search Console’s “Links” report (under “Top linking sites” or “Top linking text”) can show you some of the anchor text Google sees pointing to your site. This is particularly useful as it’s Google’s own data.
Export the backlink reports from these tools. Aim for a comprehensive dataset, especially focusing on external links.
Step 2: Categorise Your Anchor Texts
Once you have your data, the next step is to categorise the anchor texts you’ve gathered. This can be done manually for smaller datasets or with the help of spreadsheet functions for larger ones.
Go through your list of anchor texts and classify each one into the types discussed earlier:
- Branded (e.g., “Your Brand Name”)
- Naked URL (e.g., “www.yourdomain.com“)
- Generic (e.g., “click here,” “read more”)
- Exact Match (e.g., “your target keyword”)
- Partial Match (e.g., “learn about your target keyword”)
- Other/Miscellaneous (for anything that doesn’t fit neatly)
Some tools, like Ahrefs or SEMrush, may offer some level of categorisation or filtering, which can speed up this process.
Step 3: Analyse Your Anchor Text Distribution
With your anchor texts categorised, calculate the percentage of each type within your overall backlink profile. Create a simple spreadsheet with columns for “Anchor Text Type,” “Number of Links,” and “Percentage.”
- Calculate Percentages: Divide the number of links for each anchor text type by the total number of links, then multiply by 100.
- Compare Internal vs. External: If you’ve also audited internal links, compare their distribution to your external link distribution. Internal links can naturally have a higher percentage of exact or partial match anchors because you control them and use them for clear navigation and SEO.
- Look for Patterns: Observe the overall mix. Does it look natural? Are there any types that dominate disproportionately?
Step 4: Identify Red Flags & Potential Issues
Based on your analysis, look for these common red flags that indicate potential anchor text over-optimisation:
- High Percentage of Exact Match Anchors (External Links): This is the biggest red flag. While there’s no universally “safe” percentage, if exact match anchors make up a significant portion (e.g., over 10-15% for external links, especially for competitive keywords), it could signal over-optimisation. Some SEOs suggest even lower thresholds for highly competitive niches.
- Spammy or Irrelevant Anchor Text: Any anchor text that is clearly unrelated to your content, or contains spammy keywords (e.g., “buy cheap Viagra”), is a major warning sign.
- Sudden Spikes in Specific Anchor Types: If you notice a sudden, large increase in exact match or keyword-rich anchors, especially after a link-building campaign, it could indicate an unnatural pattern.
- Lack of Diversity: A profile dominated by only one or two types of anchor text, even if not exact match, can look unnatural. A healthy profile has a good mix.
- Anchor Text from Low-Quality Sources: If the over-optimised anchor text comes from low-quality, irrelevant, or spammy websites, the risk is significantly higher.
By systematically auditing your anchor text distribution, you gain clear insights into your link profile’s health and can proactively address any issues before they lead to penalties.
Rebalancing Your Anchor Text Profile: Strategies for Recovery & Prevention
Once you’ve identified issues in your anchor text distribution, it’s time to take action. The strategies for rebalancing depend on whether the links are external (backlinks) or internal.
For Existing Over-Optimised External Links
Addressing over-optimised external links is more challenging because you don’t control them directly.
- Disavow Tool (Use with Caution): Google’s Disavow Tool allows you to tell Google to ignore specific backlinks. This should be used as a last resort and only if you have strong evidence of manipulative or spammy links that are negatively impacting your site.
- When to use it: If you’ve received a manual penalty for unnatural links, or if you’ve engaged in past spammy link building and are seeing negative algorithmic impacts.
- How to use it: Create a text file listing the domains or specific URLs of the links you want to disavow. Upload this file to Google Search Console. Google provides detailed guidance on this process here.
- Caution: Incorrect use of the disavow tool can harm your SEO by disavowing valuable links. Consult with an experienced SEO professional if unsure.
- Building New, Diverse Links: The most effective long-term strategy is to dilute the impact of over-optimised anchors by building new, natural, and diverse links.
- Content Marketing: Create high-quality, valuable content that naturally attracts links. When people link to great content, they often use branded anchors, naked URLs, or partial match anchors that are contextually relevant.
- Guest Posting: When guest posting, focus on providing value and use a mix of branded, naked URL, or generic anchors in your author bio or within the article body. Avoid forcing exact match anchor text.
- Broken Link Building: Find broken links on other websites and suggest your relevant content as a replacement. This often allows for natural, descriptive anchor text.
- Public Relations (PR): Earning media mentions can lead to powerful branded or naked URL links.
For Internal Links (Your Control)
You have full control over your internal links, making them easier to adjust and optimise for a natural anchor text distribution.
- Audit and Adjust Existing Internal Links: Review your site’s internal linking structure. Identify instances where you’ve excessively used exact match anchor text.
- Prioritise User Experience: Ensure your internal link anchor text is clear, descriptive, and helpful for users. It should accurately tell them what to expect on the linked page.
- Vary Anchor Text: Instead of always using the exact same anchor text for every link to a specific page, vary it. Use a mix of branded, partial match, and even some generic anchors where appropriate.
- Example: Instead of linking “SEO guide” every time to your SEO guide, try “our comprehensive SEO guide,” “learn more about SEO,” or “this SEO resource.”
- Contextual Relevance: Ensure the anchor text is always relevant to the surrounding content and the linked page. The anchor text should flow naturally within the sentence or paragraph.
- Use Descriptive, Not Just Keyword-Rich: While internal links can be more keyword-rich than external ones, avoid keyword stuffing. Focus on making the anchor text descriptive and useful for navigation.
Best Practices for a Healthy Anchor Text Distribution
Maintaining a natural anchor text distribution is an ongoing process. By following these best practices, you can build a robust and penalty-proof link profile.
- Diversity is Paramount: Aim for a natural mix of all anchor text types. A truly natural link profile will have a significant portion of branded and naked URL anchors, followed by a healthy mix of generic, partial match, and a smaller, carefully managed percentage of exact match anchors.
- Contextual Relevance: The anchor text should always be highly relevant to the content of the linked page and the surrounding text. This helps both users and search engines understand the link’s purpose.
- User-Centric Approach: Write anchor text that is clear, concise, and helpful for users. It should make sense in the context of the sentence and encourage clicks by providing value.
- Avoid Keyword Stuffing: Never force keywords into anchor text unnaturally. This applies to both internal and external links. Over-optimising can do more harm than good.
- Monitor Your Link Profile Regularly: Use SEO tools to continuously track your anchor text distribution and backlink profile. Early detection of unnatural patterns or spammy links allows for quick intervention.
- Focus on High-Quality Content: The best way to attract natural, diverse, and high-quality links is to create exceptional content that people genuinely want to link to and share. This organic link building naturally leads to a healthy anchor text distribution.
Common Anchor Text Mistakes to Avoid
Even experienced SEOs can make mistakes. Be mindful of these common pitfalls:
- Ignoring Internal Link Anchor Text: While external links get more attention, neglecting your internal link anchor text distribution can still lead to missed opportunities for relevance signalling and user experience improvements.
- Solely Focusing on Exact Match Anchor Text for External Links: This is the classic over-optimisation trap. Relying too heavily on exact match anchors is a direct invitation for penalties.
- Not Monitoring Your Backlink Profile: A “set it and forget it” approach to link building is dangerous. Your backlink profile can change over time, and new, potentially spammy links with problematic anchor text can appear.
- Engaging in Spammy Link Building Practices: Any link-building tactic that violates Google’s Webmaster Guidelines (e.g., buying links, participating in link schemes, using PBNs) will likely result in an unnatural anchor text distribution and severe penalties.
- Using Generic Anchors Exclusively: While generic anchors are natural, relying on them too much means you’re missing opportunities to pass more specific relevance signals to search engines. A balance is key.

Maintaining a Natural Link Profile for Long-Term SEO Success
Understanding and managing your anchor text distribution is a fundamental aspect of sustainable SEO. A natural anchor text profile, characterised by diversity and contextual relevance, signals trustworthiness and authority to search engines, contributing positively to your search rankings.
Conversely, over-optimisation, particularly an excessive reliance on exact match anchor text for external links, can trigger penalties and significantly harm your site’s visibility. By regularly auditing your anchor text distribution, identifying red flags, and strategically rebalancing your link profile through natural link building and careful internal linking, you can mitigate risks and build a robust foundation for long-term SEO success. Remember, the goal is to create a link profile that looks genuinely earned and serves both users and search engines effectively.
