Crawler whitelisting
How to whitelist Backlink Exchange for backlink verification.
If your backlink is live but the checker cannot access the page, your firewall, CDN, host, or WordPress security plugin may be blocking automated verification.
Why backlink verification can fail
Backlink Exchange verifies backlinks by visiting the exact placement URL you submitted and checking the page source for the expected outgoing link. Sometimes the backlink is correctly added, but a security layer blocks our crawler before it can read the page.
Common causes include Cloudflare firewall rules, SiteGround Security, WordPress security plugins, bot protection tools, hosting firewalls, CDN security settings, rate limits, and country or IP-based blocking.
What to whitelist
Please allow verification requests from the platform domain and crawler user-agent below.
Domain: backlinkexchange.org
Crawler user-agent:
BacklinkExchangeBot/1.0 (+https://backlinkexchange.org)
If your firewall or host requires an IP address instead of a domain or user-agent, contact Backlink Exchange support and ask for the current checker server IP.
How to whitelist in Cloudflare
- Log in to your Cloudflare dashboard.
- Select your website.
- Go to Security, then open WAF or Security Rules.
- Create a new custom rule.
- Add a condition for the user-agent:
http.user_agent contains "BacklinkExchangeBot". - Set the action to Skip, Allow, or Bypass security checks, depending on your Cloudflare plan.
- Save the rule, then return to Backlink Exchange and click Re-check links now.
How to whitelist in WordPress security plugins
If you use WordPress, check your security plugin for bot blocking, firewall, or allowed user-agent settings. This applies to plugins and services such as Wordfence, Solid Security, All-In-One Security, Sucuri, SiteGround Security, and similar tools.
Add BacklinkExchangeBot to the allowed user-agent list when available. If the plugin only supports IP allowlisting, ask support for the current checker IP.
How to whitelist in SiteGround or hosting firewalls
Some hosts use server-level firewalls that website owners cannot fully edit. If you cannot find an allowlist setting, send this message to your hosting provider:
Hello,
I use BacklinkExchange.org to verify backlink placements on my website.
Their crawler needs to access my backlink placement page to confirm that the link is live. Please allow requests from:
Domain: backlinkexchange.orgUser-agent: BacklinkExchangeBot/1.0 (+https://backlinkexchange.org)
If you require an IP address, I can provide the current checker IP from Backlink Exchange support.
Thank you.
How to know it worked
- Open your exchange or chain inside Backlink Exchange.
- Confirm the submitted placement URL is the exact page where the backlink appears.
- Click Re-check links now.
- If the page is accessible and the backlink is visible in the HTML source, the status should update to Live.
The backlink still needs to be visible
Whitelisting only allows our checker to access your page. The backlink must still be a normal HTML link in the page source, for example:
<a href="https://example.com/">Example Website</a>
Avoid placing exchange backlinks only through JavaScript, blocked widgets, hidden elements, redirects, or scripts that do not appear in the initial HTML source. If a dofollow link was agreed, make sure the link is not marked nofollow, sponsored, or ugc.
Final checklist
- The backlink is on the exact URL submitted in Backlink Exchange.
- The link is visible in the page source.
- The link points to the correct partner domain.
- The link is not hidden with CSS.
- The link is not marked nofollow if a dofollow link was agreed.
- Your firewall, CDN, host, or security plugin allows the Backlink Exchange crawler.

If your backlink is live but still cannot be verified, contact support with the exchange or chain ID, the placement URL, your hosting provider or CDN name, and any firewall or security plugin you use.
