Why Bing isn't indexing your site, and how to fix it

Being indexed (added to the library Bing answers from) matters beyond Bing.com: Microsoft Copilot and Bing's AI summaries draw on the same index, so a page Bing leaves out can't be cited there either. This guide shows how to confirm what Bing has indexed, walks through each cause with the tool that confirms it, covers the "indexed in Google but missing from Bing" gap, and gives a fix order.

How do you check whether Bing has indexed your site?

You check Bing indexing in three ways: a url: search on Bing, URL Inspection for a single page, and Site Explorer for patterns across the site. Bing's help page Why is my site not in the index? says to search with "the url: search operator followed by your site URL"; "If no result is returned, then your site or page is not in the index."

With a verified site in Bing Webmaster Tools, you get more detail:

• URL Inspection "will check its status in Bing Index", and its Index card shows "when and where the URL was discovered, crawled, and indexed", plus the error and the action to take if it isn't indexed (Bing). The Live URL tab shows "exactly what the Bingbot sees while downloading a page from your site."
• Site Explorer groups your URLs into folders with Indexed, Error, Warning and Excluded counts. Bing defines Excluded as "URLs with spam violations, low rank etc." (Bing).

Site Explorer's filters map almost one-to-one onto the causes below. As of October 2026 they include "URLs that are robots.txt disallowed", "URLs with NOINDEX tag", "URLs that are redirecting", "URLs with guideline issues" and "URLs selected but not yet crawled", the last of which Bing says "could include URLs skipped due to temporary issues in Bing."

Why isn't Bing indexing my site?

Bing lists eight reasons a site or page may be missing from its index (Bing). Here they are with the tool that confirms each one:

Four of those deserve more detail.

New sites need discovery first

A new site is often simply undiscovered. Bing says that even if you submit sitemaps or pages directly, "we still need to crawl and assess it before it appears in the index", and that "We need to see at least one link pointing to your website for us to find it." Bing adds that it prefers "a few links from quality, authoritative websites pointing at you, rather than see hundreds of new links from random sites" (Bing).

Crawl problems and blocks

Crawl reliability matters to Bing. Its help page says "If we cannot crawl your website consistently, we may select not to index." robots.txt and noindex are the usual culprits, and they interact: Bing's removal guidance says that for noindex to be read, "Make sure Bingbot can access the URL so the directive can be seen during the next crawl" (Bing). So a page you want indexed needs both rules cleared, not just one. Bing's robots.txt tester shows "which statement is blocking it and for which user agent". The Google-side versions of these problems are covered in blocked by robots.txt and excluded by noindex tag, and the WordPress robots.txt guide shows how to edit the file safely.

Hidden with the Block URLs tool

The Block URLs tool is easy to forget because it lives in your Bing account, not on your site. Bing says "you may have blocked URLs from showing in our results using the Block URLs tool. Check your account and ensure that the URLs you expect to see in the index are not blocked" (Bing). A block is temporary: Bing's removal page says it "hides the content for 90 days" (Bing).

Quality: Bing's selection criteria

Quality is the cause you can't fix with a setting. Bing says "Bing likes unique, quality content" and that "Prolonged poor performance can lead us to delist websites to make room for quality websites." Its URL Submission FAQ puts it more briefly: "Bing may choose not to index specific URLs if they do not meet its selection criteria" (Bing). The next section covers what Bing's guidelines count against a page.

If your pages are fine on Bing but you don't know where Google stands, check which of your pages Google has indexed before you change anything.

What do Bing's Webmaster Guidelines count against a page?

Bing's Webmaster Guidelines describe how Bing "discovers, crawls, indexes, evaluates, and surfaces content across Bing search experiences, Copilot, and grounding API results." As of October 2026, the parts most often behind missing pages are:

• Content that can't be rendered. Bing tells you to avoid "Hiding critical content behind client-side rendering" and warns that "Content that cannot be reliably rendered may not be indexed or selected for grounding results." JavaScript-heavy sites should check the Live URL view; the React indexing guide covers the usual fixes.
• Duplicate URLs. "Duplicate URLs dilute signals and reduce Bing's confidence in selecting a URL"; consolidate with canonical URLs and consistent URL structures.
• Thin and scaled pages. "Thin, ad heavy, or affiliate-only URLs may lose ranking eligibility and grounding visibility", and "Large‑scale content generated without oversight, quality control, or editorial review ... may be excluded from indexing."
• Crawl waste. Bing "allocates crawl capacity based on site health, efficiency, signal quality, and crawl value", and excess low-value URLs can "Delay indexing of important content."
• Bingbot blocked. The guidelines list "Blocking Bingbot in your robots.txt file" among things to avoid.

Google has its own version of the quality call; see crawled, currently not indexed for how it shows up in Search Console.

Why is my site indexed in Google but not in Bing?

A site indexed in Google but missing from Bing usually has a Bing-specific gap, because Bing keeps its own settings, its own crawler and its own selection criteria. Search Console setup doesn't carry over unless you import it. The common gaps:

1. No sitemap in Bing. Bing's Sitemaps page lists the sitemaps "submitted by the users, those imported from Google Search Console and the ones that were discovered organically by Bing." If none appear, submit one, and add a Sitemap: line to robots.txt.
2. A firewall or bot filter that blocks Bingbot. Bing names crawl trouble as a reason not to index. Check your server or CDN logs for Bingbot requests that get 403 or challenge pages. User agents can be faked, so Bing says to "use the Verify Bingbot tool" to confirm an IP is really Bing's (Bing). The AI crawlers guide explains why Bingbot should stay allowed when you tighten rules for AI bots.
3. robots.txt or crawl-rate settings aimed at Bing. A rule group for bingbot, a crawl-delay, or a low Crawl Control setting slows or stops Bing alone. Bing says a crawl-delay in robots.txt "will always take precedence" over Crawl Control (Bing).
4. URLs hidden with Block URLs in a Bing account someone set up earlier.
5. Different selection. Bing and Google judge pages separately; a thin page Google kept can still fall below Bing's threshold.

For the opposite problem, see why your website isn't showing up on Google.

In what order should you fix Bing indexing problems?

Fix blocks before discovery, and discovery before quality, because nothing else counts while Bingbot can't fetch the page. This order works:

1. Confirm the status. Run a url: search, then URL Inspection on two or three affected URLs. Note the reason each one gives.
2. Remove hard blocks. Clear Disallow rules in the robots.txt tester, remove unwanted noindex tags or X-Robots-Tag headers, delete any Block URLs entries, and make sure your firewall lets verified Bingbot through.
3. Make the page fetchable. Use the Live URL tab to confirm a 200 response and that the main content is in the HTML Bingbot sees. The Live URL test "does not follow redirects", so inspect the destination separately (Bing).
4. Help Bing find it. Submit your sitemap in Bing Webmaster Tools, link the page from pages Bing already indexes, and earn at least one relevant external link for a new site.
5. Raise the quality of thin, duplicate or template pages, or merge them.
6. Tell Bing it changed. Send the fixed URLs through IndexNow (an open "this page changed" notice that Bing and other participating engines accept; Google doesn't use it), or use Request indexing in URL Inspection, which depends on your URL submission quota. The step-by-step is in how to submit URLs to Bing.
7. Re-check in a week or two in Site Explorer and URL Inspection.

How can you check a page for Bing blockers from the command line?

You can check the most common blockers from a terminal before you open Bing Webmaster Tools. This script fetches a URL as Bingbot's user agent and prints the status code, any X-Robots-Tag header, any robots meta tag, the robots.txt lines whose path matches, and the sitemap lines. It does a simple prefix match on robots.txt, so it ignores wildcards and doesn't replace Bing's tester:

#!/usr/bin/env bash
# bing-check.sh <url>: quick look for the blockers Bing lists
url="$1"
ua="Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)"
origin=$(echo "$url" | sed -E 's#(https?://[^/]+).*#\1#')
path=$(echo "$url" | sed -E 's#https?://[^/]+##'); path=${path:-/}
echo "URL:          $url"
echo "HTTP status:  $(curl -s -o /dev/null -w '%{http_code}' -A "$ua" "$url")"
echo "X-Robots-Tag: $(curl -sI -A "$ua" "$url" | grep -i '^x-robots-tag' | cut -d' ' -f2- | tr -d '\r')"
echo "Meta robots:  $(curl -s -A "$ua" "$url" | grep -o -i -E '<meta[^>]+name="(robots|bingbot)"[^>]*>' | head -3)"
echo "robots.txt lines matching this path:"
curl -s "$origin/robots.txt" | grep -i -E "^(user-agent|disallow|allow):" | awk -v p="$path" '
  tolower($1)=="user-agent:" {ua=$2; next}
  { rule=$2; if (rule != "" && index(p, rule)==1) print "  [" ua "] " $1 " " rule }'
echo "Sitemap lines: $(curl -s "$origin/robots.txt" | grep -i '^sitemap:' | tr '\n' ' ')"

We ran it against two pages on our own site on October 17, 2026. Our sign-up page is meant to stay out of search, and the output shows both blocks Bing describes:

URL:          https://freshlycited.com/sign-up
HTTP status:  200
X-Robots-Tag:
Meta robots:  <meta name="robots" content="noindex, nofollow"/>
robots.txt lines matching this path:
  [*] Allow: /
  [*] Disallow: /sign-up
Sitemap lines: Sitemap: https://freshlycited.com/sitemap.xml

Our About page, which should be indexed, came back clean: status 200, no robots meta tag or header, and only the Allow: / rule matching. If a page you want in Bing looks like the first result, that's your fix list.

How do you know the fix worked?

You know the fix worked when URL Inspection reports the URL as indexed and Site Explorer's Indexed count for that folder rises. If you sent the URLs through IndexNow, the IndexNow report's View panel shows each URL's crawl status, index status and first indexed time (Bing). Give it time; Bing says it needs to "crawl and assess" a page before it appears.

Once the pages are indexed, the AI Performance report shows whether Copilot and Bing's AI summaries cite them. For the protocol itself, our IndexNow guide has the key file rules and response codes.

Where does FreshlyCited fit?

FreshlyCited's main job is Google, not the Bing diagnosis: it checks which URLs Google already sees, pushes only the ones Google hasn't indexed, then re-checks on days 1, 3 and 7. Bing is a free bonus: for sites you verify with an IndexNow key, every push of URLs on that site also goes out through IndexNow, shown as "Sent to Bing", with a per-site off switch. It doesn't check Bing's index, so URL Inspection and Site Explorer remain your source for whether Bing kept a page.

Fix the blocks first; then make sure both engines hear about the fixed pages. Check your pages on Google free; on verified sites, the same push sends the fixed URLs to Bing.
