An internal link audit checks whether the pages on your website connect in a useful, crawlable and consistent way. Start by finding broken links, links that pass through redirects, important pages with few or no incoming links, vague anchor text and links pointing to non-canonical or outdated URLs. Then fix the issues that prevent customers and search crawlers from reaching valuable pages.

A good internal link audit is not about adding as many links as possible. It is about building clear paths between related pages and giving each link a real purpose.

What is an internal link?

An internal link takes a visitor from one page to another page on the same website. It may appear in the main menu, footer, breadcrumb, product category, related-content block or within a paragraph.

Google’s link best-practices documentation explains that links help Google discover pages and understand relevance. It also recommends crawlable <a> elements with an href attribute and meaningful anchor text.

Why should you audit internal links?

Websites change continuously. Services are renamed, products are removed, URLs are updated, campaigns expire and old articles remain online. A link that worked last year may now redirect, return an error or lead to information that no longer matches the surrounding text.

An audit helps answer practical questions:

• Can a visitor reach every important page through normal navigation?
• Do old articles link to the current service or product page?
• Are any links broken or routed through unnecessary redirects?
• Does the anchor text explain what the destination contains?
• Are several URL versions competing for internal links?
• Are high-value pages buried several steps away from the home page?

What should an internal link audit check first?

1. Broken destination URLs

A broken internal link usually points to a URL returning a 404 or another error. It interrupts the visitor’s task and wastes the context created by the source page.

Do not automatically redirect every missing URL to the home page. If a close replacement exists, update the source link to that page directly. If the destination should still exist, restore it. If there is no suitable replacement and the link is no longer useful, remove it.

2. Links that pass through redirects

A redirect is sometimes necessary after a URL change, but internal links should normally point straight to the final destination. Update links that still use an old HTTP address, a former slug, or a redirecting category URL. This reduces unnecessary steps and keeps the site’s preferred URLs consistent.

3. Orphan and underlinked pages

An orphan page has no discoverable internal link pointing to it. A page may exist in a sitemap or be accessible through a direct URL while remaining disconnected from normal browsing.

Not every page needs promotion. A temporary confirmation page, private campaign destination or utility page may be intentionally isolated. A current service page, product category or useful guide should usually be connected from a relevant hub, menu, category or article.

4. Weak or misleading anchor text

Anchor text is the visible wording of a link. Phrases such as “click here,” “read more” and “learn more” can be understandable in context, but they say little when read on their own. Prefer wording that describes the destination naturally.

For example, “review our WordPress maintenance checklist” is clearer than “click here.” Do not force an exact keyword into every link. Repeated, awkward anchors make writing harder to read and do not create a better experience.

5. Links to inconsistent URL versions

Internal links should use the preferred version of a page. Check for mixtures of HTTP and HTTPS, www and non-www, trailing-slash variations, tracking parameters and duplicate product URLs. Google’s ecommerce URL guidance recommends using the same URL in internal links, sitemap files and canonical tags.

6. Important pages hidden too deeply

Click depth describes how many link steps it takes to reach a page from a starting point such as the home page. There is no universal number that guarantees performance. The practical question is whether users can reach an important page through an obvious path.

Google’s ecommerce site-structure guidance uses a clear pattern: menus link to categories, categories link to subcategories, and subcategories link to products. The same principle works for service websites: home to service hub, service hub to individual services, and relevant guides to the service they support.

7. Links that depend only on JavaScript actions

A button may look like a link but be implemented only with a script event. Google recommends standard anchor elements with usable href destinations for crawlable links. Test the rendered page, not only the editor, because themes and page builders can change the final markup.

How do you perform an internal link audit step by step?

Step 1: List the pages that matter

Begin with primary services, product categories, popular products, lead pages and authoritative guides. Note the purpose of each page and the type of visitor who needs it. This prevents the audit from treating every URL as equally important.

Step 2: Review the available link findings

The Ishu Technology SEO Analyzer overview lists an Internal Link Checker among its on-page checks. To review a page, open the SEO Analyzer tool and inspect the options currently available.

Use automated output as a starting list rather than a final verdict. A page-level review may not reveal every orphan page across a large site, and a technically valid link may still be irrelevant or poorly placed. Confirm important findings in the live page and site structure.

Step 3: Classify each issue

Give every finding a simple label: broken, redirected, outdated, vague anchor, duplicate URL, orphan candidate, low-priority template link or no action required. Classification helps prevent random edits.

Step 4: Prioritise by user impact

Fix links that block enquiries, purchases, bookings or essential information first. Then repair links on high-traffic pages, navigation elements and current service hubs. Old archive links with little business impact can follow.

Step 5: Update the source, not only the destination

If an old link redirects successfully, it may appear functional. Still update the link on the source page to the final preferred URL. When the same old link appears site-wide, repair the template or reusable block rather than editing pages one at a time.

Step 6: Verify after publishing

Open the updated pages in a private browser window, follow the links and confirm the destination, status and context. Check both desktop and mobile navigation. Clear caches when necessary, then inspect the rendered HTML for critical links.

How do you find useful internal link opportunities?

Start with reader journeys, not keywords. A beginner’s guide may naturally link to a detailed checklist, while a comparison may link to each relevant service. When publishing a new page, find older pages that discuss the same problem and add a contextual link only where it helps the reader continue the task.

What internal linking mistakes should you avoid?

• Adding unrelated links merely to increase the link count.
• Repeating the same keyword-heavy anchor in every article.
• Sending every old URL to the home page.
• Linking to search-result pages instead of stable category pages.
• Leaving valuable pages accessible only through an on-site search box.
• Assuming a sitemap replaces normal website navigation.
• Changing many URLs without updating internal links and canonical signals.

Google notes that crawlers generally do not submit searches into an internal search box to discover products. Important content should therefore be reachable through normal links, with a sitemap serving as an additional discovery signal rather than the only path.

Frequently asked questions

How often should you run an internal link audit?

Review links after migrations, redesigns, major URL changes and large content updates. For an active website, a regular check is useful, but the frequency should match how often pages change.

Are too many internal links bad?

There is no useful universal limit for every page. Add links that support navigation or context. Remove repetitive, irrelevant or template-generated links that create clutter without helping users.

Do internal links guarantee indexing?

No. Crawlable links can support discovery, but indexing also depends on access, page quality, canonicalisation, robots directives and search-engine decisions.

Should you use nofollow on internal links?

Do not use nofollow as a routine method for organising a site. If a page should not appear in search, use the appropriate indexing control and make sure the wider navigation decision makes sense.

Turn findings into a repair queue

A useful audit ends with assigned actions: source page, current destination, preferred destination, issue type, priority, owner and verification date. Work from customer-critical paths outward, and recheck the live result after every group of changes.

If your website contains old URLs, page-builder templates or a confusing service structure and you need help turning the findings into safe updates, contact Ishu Technology with the affected URLs. The team can review the implementation context and discuss the next steps.
