What Is an Internal Links Checker?
An internal links checker is a crawler that starts at a URL and follows every link that points to the same domain. It records each connection and builds a map of your site. Think of it as a floor plan for your content. You can see the main halls, the quiet corners and the doors that lead nowhere.
A raw link count is not enough on its own. The useful part is the pattern. Which sections act as hubs, which pages sit alone and do the link words describe the pages they lead to?
What an internal link report shows
A good internal link analysis covers a handful of points, and each one gives you something to act on.
- Pages crawled. You see every page found and the number of internal links that point to it.
- Outbound links. You see which internal links each page sends out.
- Anchor text. You see the words used for each link.
- Click depth. You see how many clicks it takes to reach each page from the start URL.
- Errors and redirects. You see links that return an error or pass through a redirect.
What You Can Use an Internal Links Checker For
Most people run a crawl when they need to see the whole structure, not just one page. These are the jobs it handles best.
- A full site audit. You see the shape of the site instead of one page at a time.
- A new section launch. New pages need links from existing categories and articles, and the report shows the gaps.
- A migration. Old paths change, and internal links often still point at the previous URLs.
- An orphan page review. Some content is live, but nothing on the site links to it.
- A navigation review. Menus and footers sometimes carry too much of the linking work.
- An ecommerce audit. Products need paths from categories, filters and related item blocks.
- A content refresh. Older articles should link to newer pages on the same topic.
Every job starts with the same question. Can a visitor or a crawler reach this page through a sensible route?
How an Internal Links Checker Helps
Google uses links to find new pages and to understand how pages relate to each other. The link text helps too. A link that says "read the redirect guide" tells Google far more than one that says "click here".
- Discovery. A page with several internal links is easier to find than a page with none. A sitemap can list a URL, but a link gives crawlers a path from content they already know.
- Context. The words inside and around a link help Google see what the destination is about.
- Structure. A clear hierarchy shows which pages are broad entry points and which are detailed answers. Visitors can then move from a category to a specific page without guessing.
- Clean paths. Links that resolve, avoid long redirect chains and point at canonical URLs send crawlers and visitors straight to the right page.
No tool can promise better rankings. What Traffsite gives you is the link map you already have, and that is the part you can change.
What You Can Achieve With an Internal Links Checker
A solid internal link audit ends with a site where every important page has a clear path to it. These are the signs that you are there.
- No important page depends on the sitemap alone.
- Every section has a hub page that links to its child pages.
- Related pages link to each other where a reader would expect it.
- Anchor text describes the destination instead of repeating one phrase everywhere.
- New pages get links at launch, not months later.
A tidy link map also makes future work easier. When you add a page, you know where it belongs and which pages should point to it.
Benefits of an Internal Links Checker
Why use a dedicated internal linking tool instead of checking a few pages by hand? These are the main reasons.
- It covers the whole site. Manual checks stop at the pages you remember, while a crawl reaches the older content.
- It shows the direction of every link. A page can send many links and receive almost none, which is hard to spot without a report.
- It finds weak spots fast. Pages with a single link from a low value page stand out.
- It catches broken internal links. A path that ends in a 404 is a dead end for visitors and crawlers.
- It supports content planning. You can see which topics are well connected and which need a new hub.
- It gives editors a simple task list. Add a link here, rewrite an anchor there and remove a duplicate path.
How to Use the Internal Links Checker
You can check internal links on your site in a few quick steps.
- Enter your domain into the Traffsite tool and start the crawl.
- Sort the page list by inbound internal links. Pages with zero or one link deserve a closer look.
- Check click depth. Important pages should be reachable within a few clicks from the home page.
- Read the anchor text and look for generic labels, empty links and phrases that do not describe the destination.
- Find broken links and redirects, then fix them at the source.
- Add links from relevant parent pages and related articles. Always link to the canonical URL, not a duplicate version.
- Run the internal links checker again and compare the results.
Who Should Use an Internal Link Checker
Anyone who publishes or looks after a website can get value from this tool.
- SEO specialists use it for audits, migrations and content cluster planning.
- Content editors use it to connect new articles to existing pages.
- Developers use it to find navigation and template links that create dead ends.
- Site owners use it when a live page is not getting traffic.
- Agencies use it to show a client how the site is built and where the gaps are.
You do not need to be a developer to act on the report. Most fixes are editorial choices about where a link belongs, and Traffsite points you to the right spot.
Frequently asked questions
What does an internal links checker do?
It crawls your site, collects the links between your own pages and shows how they connect. Traffsite reports the inbound and outbound links for each page, the anchor text, the click depth and any links that end in an error.
What is the difference between internal and external links?
Internal links connect pages on the same site. External links point to other sites. An internal links checker looks only at the first kind, which are the links you fully control.
Why are internal links important for SEO?
Google uses links to find new pages and to understand how pages relate to each other. A page with several relevant internal links is easier to discover than a page with none, and the link text gives context about what the destination holds.
How many internal links should a page have?
There is no fixed number. A short article may need three or four useful links, while a category page may need dozens. The test is relevance. Every link should help the reader reach a page that answers their next question, and the same destination should not repeat in several places.
What is crawl depth?
Crawl depth is the number of clicks needed to reach a page from the home page. Pages that sit closer to the surface are easier for visitors and crawlers to find, so keep your important pages within a few clicks.
Do internal links need to be in the HTML?
Yes. Google can generally crawl a link only when it is an anchor element with an href attribute. A clickable div or a link that appears only after a user action may not be found, so keep your key links in the HTML.
