Turning AFFINGER5 Related Posts into Affiliate Revenue

For niche blogs that earn a living from affiliate links, every square centimetre of screen real estate matters. The related posts block at the bottom of a WordPress article is one of the most underused assets on the page. I spent the first year of running this site ignoring it, then rebuilt the layout with AFFINGER5 and treated that footer area like a strategic recommendation engine. Affiliate revenue from internal clicks roughly tripled within two quarters.

AFFINGER5 ships with a native related posts function that pulls from tags, categories, or custom post types. Most tutorials cover the visual settings, but the real lever is what you let the block recommend. Once I started surfacing review-style and comparison-style articles instead of loosely connected posts, click-throughs on monetised links climbed steadily.

Running a blog from Brisbane means my audience is mostly Australian, with smaller slices in New Zealand, Singapore, and the UK. Australian readers scan quickly, skim longer posts on mobile, and tap on articles that look specific rather than generic. That behaviour shaped every choice I made with the related posts feature, from thumbnail size to the exact articles the block pulls.

Why I Chose AFFINGER5's Built-In Related Posts

I tried three plugins before deciding that none were necessary. Jetpack, YARPP, and Contextual Related Posts all worked, but each added CSS that clashed with AFFINGER5's styling. The native block loads inside the same stylesheet, so thumbnails, fonts, and hover effects stay consistent with the theme.

Another reason is control. Plugins often ship a settings page outside the customiser, and updates occasionally reset fields. AFFINGER5 lets me configure the block from the post editor or the theme options panel, and the configuration travels with each article. When I publish a new review, I decide on the spot whether it should appear as a related recommendation on existing posts.

The block also respects custom post types, which matters because I run a separate CPT for product reviews. Plugins often ignore CPTs or require premium upgrades. AFFINGER5 handled the setup with a single checkbox, which saved me an afternoon of debugging.

Configuring the Block for Affiliate Conversions

The default configuration looks fine but rarely converts. I treat the related posts block like a miniature landing page, so I work through each setting before saving the article.

Settings worth tweaking first:

• Layout: card style with a 16:9 thumbnail, since most Australian readers browse on iPhones and Samsungs.
• Number of posts: three cards per row, repeated across one or two rows depending on article length. Anything beyond nine starts to feel spammy.
• Display order: newest first by default, with a custom override when running a promotion for a specific affiliate partner.
• Exclusions: the current post and any tag combinations that do not match buyer intent, which keeps the recommendations tight.

Thumbnails are the biggest conversion lever I have found. A blurry or cropped image makes the recommendation look like filler. I create custom featured images at 1200x630 pixels and let AFFINGER5's built-in crop tool handle the rest, which keeps the cards sharp on every device.

Matching Related Content to Buyer Intent

Not every article deserves the same kind of related recommendation. A reader finishing a "best slow cookers under $300" review is in purchase mode. A reader finishing a "how to meal prep for shift workers" article is in research mode. Sending the same three articles to both groups wastes the slot.

I organise my post library into three intent buckets. The first covers top-of-funnel educational pieces that build trust. The second covers comparison and review articles where affiliate links live. The third covers deep technical guides that close the loop. When I write a review, the block pulls from bucket two first, then bucket three.

The block does not embed affiliate links itself, but it funnels readers toward articles that do. A review about a specific product might link sideways to a broader how to write product reviews that convert readers into buyers guide, which in turn points readers toward monetised comparisons. Each step is a small nudge, and the nudges add up across a session.

Where to Place the Block in Your Articles

Placement matters more than most bloggers realise. I tested the block above the comments, embedded mid-article after the second subheading, and tucked into a sidebar widget. Mid-article won for session depth, and below-article won for affiliate clicks. I now use both, with different content in each slot.

The below-article block is where I drop my strongest money pages. The mid-article block holds transitional pieces that move a reader from one product category to another. Both placements use the same AFFINGER5 shortcode, but I label them differently inside the editor so I can tell them apart in analytics.

For Australian readers in particular, mobile scroll depth drops off sharply after about 60 percent of the article. Placing the block before that drop-off point means it loads while the reader is still engaged. Anything below the fold often goes unseen on a quick mobile read.

Tracking Which Recommendations Get Clicked

A related posts block that is not measured is just decoration. I attach event tracking to every card using Google Tag Manager, then forward the events into a Looker Studio dashboard that I review every Sunday morning over a flat white at my local cafe in West End.

The dashboard breaks down click-through rate by source article, by recommended article, and by device. The first month revealed that one of my top traffic pages was sending almost no internal clicks to a comparison article I assumed readers would find useful. The recommendation was relevant, but the thumbnail did not match the visual style of the surrounding posts. A quick featured image rebuild fixed it.

I also tag related posts blocks with UTM parameters pointing back to my own domain. This lets me separate internal recommendation clicks from organic navigation in tools like Matomo and Plausible, which are popular with Australian privacy-focused bloggers. Knowing the difference is the only way to know whether the strategy is actually working.

Refresh Cycles and Seasonal Updates

Affiliate offers change constantly, and the related posts block can quietly become outdated. A few clear signs tell me it is time for a refresh.

Signs the block needs a refresh:

• An affiliate partner has ended its program or shifted commission tiers.
• A product in the recommended article has been discontinued or replaced by a newer model, especially in tech and kitchen niches.
• The thumbnail style on related cards no longer matches the featured images I use on newer posts, which breaks visual trust.
• Search Console shows declining click-through rates on pages that rely on internal traffic from the block.

I run a quarterly audit where I open every article in my top twenty traffic slots and check what the block currently recommends. Anything that fails one of the checks above goes onto a swap list.

Australia has its own seasonal rhythm that affects affiliate conversions. Summer recommendations for travel gear spike between November and February, while winter content around heaters and slow cookers rises between June and August. I rotate related posts to match the southern hemisphere calendar rather than the northern hemisphere default that most themes assume. AFFINGER5 sorts by date by default, so a fresh January article about summer products will outrank a winter piece that is more relevant in July.

The actual refresh takes about twenty minutes per batch of ten articles. I keep the swap list in a spreadsheet so I do not have to think through each one from scratch. Returning readers notice when recommendations stay current, and search engines reward the freshness signal too.

A Real Campaign Example From My Niche

A few months ago I ran a small campaign around electric pressure cookers. The lead article was a long-form comparison ranking for "best pressure cooker Australia" style queries. I configured the related posts block to surface three supporting pieces: a beginner's guide, a recipe round-up, and a maintenance tutorial. None carried affiliate links, which kept the funnel feeling honest.

Within six weeks, the related posts block drove a 38 percent lift in internal clicks from the comparison article to the supporting pieces, and the supporting pieces pushed a 22 percent lift in clicks toward a separate article with affiliate links. Total revenue from that cluster beat my previous quarter by a comfortable margin, and the only real change was the related posts configuration.

That kind of result is repeatable. The theme handles the heavy lifting, the analytics show what is working, and the content does the rest. Affiliate income grows quietly in the background while the blog keeps helping readers in Australia and beyond make better buying decisions.
