How to Do SEO for Affiliate Sites Post-HCU

Start by correcting the premise: there’s no standalone “helpful content update” left to escape. Google’s guide to its ranking systems lists the helpful content system among its retired systems and says that in March 2024 it became part of the core ranking systems. The same guide lists a reviews system that is still active, aimed at rewarding high-quality reviews. So recovery for an affiliate site isn’t waiting for a penalty to lift. It is making review content that shows real use and adds something the merchant’s page doesn’t, and cutting the production habits Google’s spam policies name.

What Google’s policies say about affiliate content

Two definitions from Google’s spam policies mark the boundary:

• Thin affiliation is publishing content with product affiliate links where the product descriptions and reviews are copied directly from the original merchant without any original content or added value. The same section says not every site that participates in an affiliate program is a thin affiliate.
• Scaled content abuse is focused on creating large amounts of unoriginal content that provides little to no value to users, no matter how it’s created.

Neither definition is about having affiliate links. Both are about pages that add nothing. A review site built on spec recaps rewritten from product listings, published at volume, sits close to both.

What Google asks a review to show

Google’s guidance on writing high-quality reviews is specific. Among other things, it asks reviews to:

• provide evidence such as visuals, audio or other links of your own experience with what you’re reviewing
• share quantitative measurements of how something performs
• cover comparable products, or explain which might be best for certain uses
• discuss benefits and drawbacks based on your own original research
• consider linking to multiple sellers, so the reader can choose where to buy

Buying a product, taking snapshots and sending it back covers the first item at best. Measurements, drawbacks that only show up with use, and honest comparisons with alternatives come from using the thing. The practical test for each review: would a reader learn something they couldn’t get from the product listing?

The economics of first-hand reviews

That standard has a cost. A small team can’t use hundreds of products across a dozen unrelated categories in any depth, so a site built that way ends up mostly secondhand by construction. The recovery path runs against the old growth plan: narrow to categories you can test, publish fewer reviews with real evidence, and accept a smaller catalog. Depth in one area is also harder for competitors to copy than breadth across everything.

Improve before you prune

When an audit finds weak reviews, the order matters. Google’s core updates documentation calls deleting content a last resort, for content you think can’t be salvaged. For an affiliate site, that means:

1. Rebuild reviews you can test into first-hand reviews.
2. Merge thin reviews of similar products into one comparison you can stand behind, and redirect the old pages.
3. Remove the pages that are merchant copy with a link and nothing you can add.

The ranking systems guide says Google’s systems work on the page level and also use site-wide signals, and that neither good nor poor site-wide signals decide how every page ranks. There’s no percentage of pages to hit; each review has to earn its place.

Label the links

Google’s guide to qualifying outbound links says to mark advertisements and paid placements with rel="sponsored", and that nofollow remains acceptable for these links though sponsored is preferred. Affiliate links pay you when a reader buys, so treat them as paid links. The review guidance points affiliate sites to Google’s position on affiliate programs. Tell readers plainly that you earn a commission, too; it’s part of what makes a review trustworthy.

Reduce the dependency

A site that earns only from affiliate commissions on search traffic depends on rankings for all of its revenue. Part of recovery is strategic rather than algorithmic: an email list or community you can reach without search, display revenue, or products and services of your own, so a ranking change is a setback rather than the end of the business.

Real expertise, not a costume

An author bio with an invented name and a stock photo adds nothing a reader can check. What counts is visible in the review: the evidence of use, the measurements, the drawbacks and the comparisons. If a named author reviews products, the reviews themselves should show why that person’s testing deserves trust.

Frequently asked questions

Is there still an HCU penalty to recover from?

No. Google’s ranking systems guide lists the helpful content system as retired and says it became part of the core ranking systems in March 2024. The reviews system is still listed as active.

Are affiliate links against Google’s policies?

No. Google’s spam policies say not every site in an affiliate program is a thin affiliate. The problem is content copied from the merchant without original content or added value. Affiliate links pay you when a reader buys, so treat them as paid links and qualify them with rel="sponsored", the value Google’s guide asks for on ads and paid placements.

How long does affiliate recovery take?

Google gives no fixed timeline. Its core updates documentation says improvements can show before a major core update, and that after a few months with no effect, you may need to wait for the next one.
