Redirect Checker and Google Index Checker Tools: Find Redirect Chains and Indexing Problems Fast

A site migration goes live on Friday. By Monday, organic traffic is down 30%. The content didn’t change and no penalty arrived. The cause is usually hiding in plain sight: redirects pointing to the wrong place, chains of three or four hops, a few accidental 302s, and a batch of important pages that Google quietly dropped from its index.

These are some of the most common and most fixable technical SEO problems, and two simple types of tools catch them: a redirect checker and a Google index checker. This guide explains what each does, compares the best free and paid options, and gives you a repeatable process to find and fix issues before they cost you traffic.

Redirects 101: The Status Codes That Matter

When a browser or Googlebot requests a URL, the server answers with an HTTP status code. For redirects, the important ones are:

Google’s documentation on redirects and Google Search explains that permanent redirects are a strong signal that the target should be shown in search results, while temporary redirects are a weaker signal. In practice, use 301 for anything permanent.

Redirect Problems That Hurt SEO

• Redirect chains: A → B → C → D. Each hop adds latency, and Googlebot may stop following after several hops.
• Redirect loops: A → B → A. The page never loads for users or crawlers.
• Wrong type: 302s used for permanent moves can delay Google consolidating signals to the new URL.
• Redirects to irrelevant pages: sending every old URL to the homepage is often treated as a soft 404.
• Internal links to redirected URLs: wasted crawl requests and slower pages for users.
• Mixed signals: a URL that redirects but is also listed in your sitemap or set as a canonical target.

The Best Redirect Checker Tools

1. httpstatus.io (Free)

Paste up to around a hundred URLs and see the full redirect path for each, with every hop’s status code. It’s ideal for spot-checking a migration list or verifying a handful of fixes.

• Best for: bulk checks of a URL list
• Pros: fast, clear chain display, export options
• Cons: doesn’t crawl your site to discover URLs

2. Redirect Path (Chrome Extension, Free)

This browser extension by Ayima shows a small icon whenever a page redirects. Click it to see every hop and status code, including client-side redirects. It’s perfect for checking pages as you browse.

• Best for: on-the-fly checks while browsing
• Pros: instant, shows JavaScript and meta refresh redirects
• Cons: one page at a time

3. Screaming Frog SEO Spider (Free up to 500 URLs / Paid)

The desktop crawler is the workhorse for site-wide audits. Crawl your site, then open the Response Codes tab and filter by “Redirection (3xx).” The Reports → Redirects export shows full redirect chains and loops, and you can upload a list of old URLs in List Mode to audit a migration map.

• Best for: full-site redirect audits and migrations
• Pros: finds internal links pointing to redirects, detects chains and loops at scale
• Cons: learning curve, and the free version is limited to 500 URLs

4. Ahrefs / Semrush Site Audit (Paid)

Both suites flag redirect chains, loops, 3xx pages in sitemaps and broken redirects as part of scheduled cloud audits. They’re useful for ongoing monitoring, with email alerts when new issues appear.

• Best for: teams that already pay for an SEO suite
• Pros: scheduled crawls, issue prioritisation, history
• Cons: subscription cost

5. Command Line: curl (Free)

For developers, curl -sIL https://example.com/old-page prints the headers for every hop. It’s quick for single URLs and easy to script.

6. Rank Math / Redirection Plugin Logs (WordPress, Free)

WordPress redirect managers record 404s and redirect hits. Reviewing these logs shows which old URLs still get traffic and need a proper redirect.

What Is a Google Index Checker?

A Google index checker tells you whether specific URLs are in Google’s index, meaning eligible to appear in search results. A page that isn’t indexed gets zero organic traffic, no matter how good it is.

Note that Google limits automated querying of its search results, so third-party “bulk index checkers” that scrape Google are often unreliable or short-lived. The most accurate data comes from Google itself.

The Best Google Index Checker Methods

1. Google Search Console URL Inspection (Free, Most Accurate)

Paste a URL into the inspection bar at the top of Search Console. You’ll see whether it’s on Google, the canonical Google selected, the last crawl date, and whether it’s blocked by robots.txt or noindex. You can also run a live test and request indexing. The downside is that it works one URL at a time, and indexing requests have a daily quota.

2. Search Console Page Indexing Report (Free)

Under Indexing → Pages, you see how many pages are indexed and grouped reasons for those that aren’t, such as “Crawled – currently not indexed,” “Discovered – currently not indexed,” “Duplicate without user-selected canonical,” “Page with redirect” and “Excluded by ‘noindex’ tag.” Filter by sitemap to check a specific set of URLs. This is the best site-wide index checker available.

3. URL Inspection API (Free, with Quotas)

Google offers a URL Inspection API that tools like Screaming Frog can connect to. In Screaming Frog, go to Configuration → API Access → Google Search Console, enable URL Inspection, and crawl. Each URL gets its index status as a column. Daily limits apply per property, so prioritise important pages.

4. The site: Operator (Quick, Rough)

Searching site:example.com/page-url gives a rough indication of whether a page appears. It’s handy for quick checks but not authoritative. Results can be incomplete, and counts for whole-site searches are estimates.

Step-by-Step: A Combined Redirect and Index Audit

1. Crawl the site with Screaming Frog or your audit tool, with the Search Console API connected.
2. Export all 3xx URLs and the internal links pointing to them.
3. Fix chains: update each redirect so the first URL points directly to the final destination.
4. Fix loops immediately, because these pages are completely inaccessible.
5. Change permanent 302s to 301s.
6. Update internal links to point straight to final URLs instead of relying on redirects.
7. Clean your sitemap so it only lists 200-status, indexable, canonical URLs. Our guide to splitting large sitemaps helps with big sites.
8. Check index status of key pages in the Page Indexing report and with URL Inspection.
9. Diagnose unindexed pages by reason (see below).
10. Request indexing for your most important fixed pages, within quota, and resubmit the sitemap.

Fixing Common “Not Indexed” Reasons

• Excluded by noindex: remove the noindex tag if the page should rank. Check SEO plugin settings and category or tag archive defaults.
• Blocked by robots.txt: remove the disallow rule. Blocking crawl doesn’t remove pages from the index cleanly, so use noindex for that.
• Page with redirect: expected for redirected URLs. Just make sure they’re not in your sitemap.
• Duplicate, Google chose a different canonical: consolidate similar pages, and set clear canonicals. See our canonical URLs guide.
• Soft 404: thin or empty pages, or redirects to irrelevant pages. Add substance or return a real 404 or 410. Our article on fixing soft 404s covers this in depth.
• Crawled – currently not indexed: Google saw the page but didn’t think it was worth indexing yet. Improve uniqueness and depth, add internal links from strong pages, and be patient.
• Discovered – currently not indexed: Google knows about the URL but hasn’t crawled it. Often a crawl budget or site quality signal. Improve internal linking and server speed.

How to Set Up Redirects Correctly in WordPress

Once your checker has found problems, you need a clean way to fix them. On WordPress there are three main options, and choosing the right one prevents new problems later.

Option 1: An SEO Plugin’s Redirect Manager

Rank Math (Redirections module) and AIOSEO (Redirection Manager, in paid plans) let you add 301, 302, 307, 410 and 451 rules from the dashboard. Rank Math can also create redirects automatically when you change a post’s slug, which stops new 404s from appearing whenever an editor tweaks a URL. Keep auto-redirects switched on, but review them occasionally, because repeated slug edits can quietly create chains.

Option 2: The Redirection Plugin

The free Redirection plugin is a dedicated, mature tool with 404 logging, regex rules, import and export, and grouping. It’s a good choice if your SEO plugin doesn’t include redirects, or if you need complex pattern matching such as redirecting an entire old folder structure.

Option 3: Server-Level Rules

Redirects in .htaccess (Apache, LiteSpeed) or the Nginx config run before WordPress loads, so they’re the fastest option. They’re ideal for site-wide rules such as HTTP to HTTPS, non-www to www, or an old domain to a new one. A typical HTTPS rule on Apache looks like this:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [L,R=301]

Always back up the file before editing, because a single typo can take the whole site down. Many hosts also offer HTTPS and www redirects as a one-click setting, which is safer.

Avoid Stacking Systems

The most common cause of chains we see is the same redirect existing in two places, for example a hosting panel rule forcing www followed by a plugin rule forcing HTTPS. The result is http://example.com → http://www.example.com → https://www.example.com. Combine site-wide rules into one step at the server level, and use a plugin only for page-level redirects.

Reading the HTTP Headers Yourself

Knowing how to read a raw response helps you trust (and double-check) any tool. When you run a redirect checker or curl -I, look for three things in each hop:

• The status line, for example HTTP/2 301
• The Location header, which shows where the redirect points
• Cache headers, because browsers cache 301s aggressively, so test changes in a private window or with a command-line tool rather than your everyday browser

Mozilla’s developer documentation on HTTP redirections is an excellent reference if you want to understand each code in more depth.

Real-World Example: Cleaning Up After an HTTPS Switch

A small e-commerce site moved to HTTPS and changed its product URL structure from /product.php?id=123 to /products/blue-cotton-shirt/ in the same month. Three months later, a crawl revealed:

• Over 1,200 internal links still pointing to the old HTTP URLs, each passing through two or three redirects
• About 80 old product URLs redirected to the homepage because no mapping existed
• The XML sitemap still listing HTTP URLs
• Search Console reporting a large number of “Page with redirect” and “Soft 404” entries

The fix took one afternoon: a single server rule for HTTPS and www, a mapped list of old product IDs to new slugs, a search-and-replace of internal links in the database, and a regenerated sitemap. Within a few weeks, the soft 404s cleared from the Page Indexing report and crawl activity shifted to the real product pages. Nothing fancy, just the redirect and index checks in this guide, run in order. The lesson: when you change URLs and protocols at the same time, plan redirects and internal link updates together, not one after the other.

Migration Checklist: Redirects Done Right

Most redirect disasters happen during migrations. Before any URL change:

• Export every URL with traffic or backlinks from Search Console, analytics and a backlink tool
• Map each old URL to the most relevant new URL, one-to-one where possible
• Implement 301s on the server, or with a plugin for WordPress
• Test the full map in List Mode before and immediately after launch
• Keep redirects in place for at least a year, and ideally permanently
• Monitor the Page Indexing report and 404 logs weekly for the first two months

Which Tools to Use on Your Budget

You don’t need expensive software to do this well. The free combination of Search Console, Redirect Path and Screaming Frog’s free tier covers most small sites completely.

A 20-Minute Monthly Routine

1. Open the Page Indexing report and compare the indexed count with last month. Investigate any sudden drop.
2. Check the top “Why pages aren’t indexed” reasons and click into any that grew.
3. Review your redirect plugin’s 404 log for old URLs still getting hits, and add redirects where a close match exists.
4. Run a quick crawl and filter for 3xx internal links, then update the worst offenders.
5. Inspect your five most important pages with URL Inspection to confirm they’re indexed with the correct canonical.

Put it on the calendar for the first Monday of each month. Twenty minutes of prevention beats a week of recovery after a traffic drop.

Frequently Asked Questions

How many redirects in a chain is too many?

Aim for zero chains: one hop, straight to the destination. Google can follow several hops, but each one slows users down and adds risk.

Do 301 redirects lose link equity?

Google has said that 3xx redirects don’t cause PageRank loss. Relevance still matters, so redirect to an equivalent page, not just the homepage.

Why isn’t my new page indexed after a week?

New pages on smaller or newer sites can take time. Make sure it’s in your sitemap, linked from relevant pages, not noindexed, and request indexing once.

Are bulk Google index checker websites accurate?

Often not, because they rely on scraping search results. Search Console’s Page Indexing report and URL Inspection API are the reliable sources.

Should I redirect deleted pages or let them 404?

Redirect if there’s a close equivalent with the same intent. If not, a 404 or 410 is the honest, correct response.

Can redirects slow down my site?

Each redirect adds a round trip before the page starts loading, which is especially noticeable on mobile connections. One hop is barely noticeable, but chains of three or four can add a visible delay. Updating internal links to final URLs removes that cost entirely for most visitors.

How often should I run a redirect audit?

Monthly for active sites, and always before and after a redesign, migration or URL structure change.

The Bottom Line

Redirect and indexing problems rarely announce themselves, but they quietly drain traffic. Use a redirect checker such as httpstatus.io, Redirect Path or Screaming Frog to eliminate chains, loops and wrong status codes, and rely on Search Console’s Page Indexing report and URL Inspection to confirm which pages Google has actually indexed. Make it a monthly habit and you’ll catch problems long before they show up as a traffic drop. For more free utilities, browse our 50 free SEO tools.
