Set one sitewide rule first, then handle exceptions. That is the safest way to manage nofollow and sponsored links across hundreds of product reviews on a WordPress affiliate site. Google says paid links and affiliate-style placements should be marked with rel="sponsored", while nofollow can be used when you do not want to pass ranking signals [source: Google Search Central]. If you try to fix each review by hand, you will miss something. You always do.
TLDR: Use WP Links, based on the WordPress plugin at wordpress.org/plugins/wp-external-links, to apply rules to outbound affiliate URLs in bulk. For example, if your site has 420 product reviews and each review has 6 affiliate buttons, that is about 2,520 links to check. A sitewide rule can mark those links as sponsored and nofollow in minutes, then you can exclude trusted editorial links. This cuts audit work by hours and lowers the risk of a messy manual update.
Why affiliate review sites need strict link rules
Product review sites collect links fast. Review buttons. Price comparison tables. “Buy on Amazon” boxes. Coupon links. Manufacturer links. Comparison posts. Old roundups that nobody has touched since 2021.
That pile becomes risky when your link rules are inconsistent. One review may use rel="nofollow sponsored". Another may use nothing. A third may have links added by a table plugin that does its own thing. Honestly, it feels like every plugin has a different opinion about outbound links.
Both nofollow and sponsored belong in your affiliate workflow:
rel="sponsored"tells search engines the link is paid, affiliate, or commercial.rel="nofollow"tells search engines not to treat the link as a normal endorsement.rel="noopener"improves security when links open in a new tab.rel="noreferrer"can hide referral data, but may affect affiliate tracking, so test it first.

Use WP External Links as the control layer
The reason WP External Links works well for large affiliate sites is simple. It lets you set rules at the WordPress level instead of editing every post. That matters when you have hundreds of reviews and a backlog of old content.
Start by installing the plugin from the WordPress plugin directory, then review the settings for external links. Your first goal is not perfection. Your first goal is control.
A sensible default setup looks like this:
- Open external links in a new tab.
- Add
rel="noopener"for security. - Add
rel="nofollow"to external commercial links. - Add
rel="sponsored"to affiliate and paid links. - Keep internal links untouched.
- Create exceptions for sources, references, and trusted non-commercial sites.
Do not apply one blunt rule to every outbound link without review. A source link to a government report is not the same as an affiliate button. Treat them differently. That is the whole point of using rules and exceptions.
Build a clean affiliate link policy
Before changing settings, write a short policy. Keep it boring. Boring is good here.
Your policy can say:
- All affiliate links must include
rel="sponsored". - Affiliate links may also include
nofollow. - Editorial source links should not be marked as sponsored.
- Internal links should stay followable unless there is a clear reason.
- Any new affiliate program must be added to the link rules before publishing.
This gives writers and editors a clear standard. It also helps when you bring in freelancers. Without a policy, expect to waste time on tiny fixes that should never reach review.
Group affiliate domains and patterns
Most affiliate sites use repeated domains. Amazon. ShareASale. Impact. Awin. CJ. Partnerize. Brand stores. Tracking subdomains. Short links. These are perfect for rule-based handling.
In WP External Links, use the plugin’s options to manage external link behavior and set exceptions. Depending on your setup, you may group rules by domain, link pattern, or class. If your affiliate buttons use a CSS class such as affiliate-button, keep that class consistent across the site. It makes audits easier.
For large sites, create a simple spreadsheet with these columns:
- Affiliate network
- Tracking domain
- Final merchant domain
- Required rel value
- Notes on tracking
- Date checked

Test before changing every review
Do not switch on a sitewide rule and walk away. Test first on a staging site, or at least on a small group of posts. Link handling can affect buttons, comparison tables, cloaked links, and redirect plugins.
Check these items after enabling rules:
- Open a review post in a browser.
- Right-click an affiliate button and inspect the HTML.
- Confirm the link contains
rel="sponsored nofollow", or your chosen order. - Click the button and confirm affiliate tracking still works.
- Check that source links are not wrongly marked as sponsored.
- Check that internal links did not change.
It drives me crazy when a setting saves correctly but takes a cache clear before the front end reflects it. Clear your page cache, object cache, CDN cache, and browser cache before judging the result.
Audit old reviews in batches
Once your rules work, audit content by section. Do not try to fix the whole site in one sitting. That is how mistakes slip through.
Use this order:
- Top revenue pages first. These pages carry the most risk and value.
- Newest reviews second. They should match your current policy.
- Old roundups third. They often hide forgotten affiliate links.
- Expired deals last. Remove dead links while you are there.
If you have analytics, sort by revenue or clicks. A page with 8,000 monthly visits matters more than a review that gets 12. Fix the pages that people actually see.
Keep the system clean going forward
The real win is not the first cleanup. It is stopping the same problem from coming back.
Add link checks to your publishing process. Before a review goes live, inspect one affiliate button, one text affiliate link, one source link, and one internal link. That takes two minutes. It saves painful cleanup later.
WP External Links gives you the control layer, but your team still needs habits. Use rules. Use exceptions. Keep a short affiliate link policy. Review settings after major plugin updates. If your site depends on product reviews for income, link hygiene is not optional. It is basic maintenance.
