How to Find and Fix Thin Content in WordPress

Thin content is the most common problem I find when auditing WordPress sites. Not broken pages. Not missing images. Thin content — articles that are too short, too shallow, or too generic to compete for their target keyword.

Google's helpful content system evaluates your site holistically. When a significant portion of your articles are thin, it doesn't just hurt those individual pages — it drags down your entire domain's quality signal. Every thin page is dead weight that makes your good content rank worse.

I've cleaned up thin content across 12 content sites with 1,000+ articles combined. Here's the exact process I follow.

What Counts as Thin Content?

There's no universal word count that makes content "thin." A 300-word answer to "how long do box turtles live?" might be perfectly adequate — the answer is straightforward and doesn't need 2,000 words of padding. But a 300-word article titled "Complete Guide to Box Turtle Care" is thin by definition — you can't cover housing, diet, lighting, humidity, health, and behavior in 300 words.

The real test isn't word count — it's whether the article adequately answers the search query someone would type to find it. But word count is a useful proxy for finding candidates that need review.

My thresholds:

• Under 300 words: Almost certainly thin. Either delete, merge, or completely rewrite.
• 300-600 words: Probably thin unless it's a very specific, narrow question. Review each one.
• 600-800 words: Might be fine for narrow topics, but likely needs expansion for competitive keywords.
• 800+ words: Usually adequate, but still check against competitors. If the top 5 results average 2,500 words and yours has 900, it's relatively thin even if it's not absolutely thin.

The key word is "review." Finding thin content is step one. The decision about what to do with each piece is where the judgment comes in.

How to Find Thin Content

On a 20-post site, you can eyeball it. On a 100+ post site, you need a tool.

Method 1: ScanMyPosts Plugin

ScanMyPosts has a dedicated thin content scanner. Set your word count threshold (I use 800), click scan, and it returns every post below that threshold with the title, word count, and a direct edit link. The free version shows up to 20 results. The Pro version shows all results and lets you export them as CSV.

This is the fastest method for a one-time audit. It takes about 30 seconds and gives you a clean, actionable list.

Method 2: AI-Powered Audit via MCP

If you have Connect My Site to AI installed, you can ask Claude to find thin content and get richer context. Instead of just a list of short posts, Claude can read the thin articles, check what competitors are ranking for the same keywords, and tell you whether each article needs expanding, merging, or deleting.

I covered this workflow in detail in my post about letting AI audit The Turtle Hub. The AI approach is slower than a plugin scan but gives you more actionable recommendations.

Method 3: Google Search Console

Search Console won't tell you word counts, but it tells you something more important: which pages Google considers low-quality. Check your "Pages" report under Indexing. Pages marked "Crawled — currently not indexed" are often thin content that Google discovered but decided wasn't worth including in search results. That's Google explicitly telling you it doesn't think the page is good enough.

The Decision Framework: Delete, Merge, or Rewrite

Once you have your list of thin content, each article gets one of three actions. This is the framework I use across all my sites, and it's the same one I described in my content pruning strategy.

Delete

Delete when the topic isn't worth targeting, the content is irrecoverably bad, or you have no way to make it competitive.

Examples from my sites:

• A 200-word post about a turtle species so rare that there are 5 monthly searches for it globally. Not worth the effort to expand.
• A news-style post about an event from 2 years ago. Time-sensitive content that's permanently stale.
• A post targeting a keyword dominated by authoritative medical or veterinary sites. E-E-A-T requirements make it impossible for my niche blog to rank.

When you delete, redirect the URL to the most relevant remaining page. Never leave a 404 behind — it wastes backlink value and creates a bad user experience. I covered redirect management in my post about automating WordPress tasks with AI.

Merge

Merge when you have two or more articles covering the same topic, and combining them would create one strong piece instead of two weak ones.

This is the most common action I take with thin content. Real examples:

• Two posts about red-eared slider feeding — "What Do Red-Eared Sliders Eat?" (450 words) and "Red-Eared Slider Diet Guide" (600 words). Neither is comprehensive alone. Merged into one 1,800-word guide covering everything: commercial pellets, vegetables, protein sources, feeding schedule, portion sizes, foods to avoid.
• Three separate posts about aquarium water parameters for different fish species. Each was 350-500 words. Merged into a comprehensive 2,200-word water quality guide with sections per species.

The merge process: take the best content from all source articles, combine it into the article with the strongest URL (most backlinks, best current ranking), expand where needed, and redirect all other URLs to the merged article. The result is one authoritative piece instead of several competing weak ones.

Rewrite

Rewrite when the topic is worth targeting and the article is the only one covering it, but the current content is inadequate.

A rewrite isn't adding a paragraph to a thin article. It's starting from scratch with the same URL. Research what the top-ranking competitors cover, outline a comprehensive structure, and write something genuinely better.

Examples:

• A 400-word post about setting up a turtle basking area. The topic gets 1,200 monthly searches and the top results are 1,500-2,000 words with photos. Complete rewrite to 2,000+ words with step-by-step instructions, equipment recommendations, and temperature guides.
• A 500-word gift guide for dog lovers. Competitors have 30+ gift recommendations with photos and descriptions. Rewrote to 25 curated recommendations with affiliate links, organized by price range.

Rewrites keep the existing URL, which preserves any backlinks and ranking history. Don't create a new URL for the rewritten content — you'd lose whatever authority the old URL had accumulated.

How I Prioritize

When you find 20+ thin articles, you can't fix them all at once. Here's my prioritization order:

• First: Merge duplicates. These give you the fastest improvement because you're combining existing content, not creating new content from scratch. And you're eliminating keyword cannibalization at the same time.
• Second: Delete no-hopers. Quick wins. Remove the dead weight so your remaining content benefits from improved overall site quality.
• Third: Rewrite high-potential articles. These take the most time but have the highest individual payoff. Prioritize by keyword search volume — rewrite the article targeting 1,200 monthly searches before the one targeting 100.

This order means your first week of cleanup produces the most impact per hour invested. The rewrites can be spread over weeks or months — they're important but not as time-sensitive as the merges and deletes.

Preventing Thin Content Going Forward

Fixing existing thin content is reactive. Prevention is better. Here's what I do now before publishing any new article:

• Check competitor length before writing. If the top 5 results average 2,000 words, my article needs to be at least that long. Not because word count is a ranking factor — because covering the topic thoroughly requires that many words.
• Set a minimum quality bar. No article publishes under 800 words on any of my sites. If I can't write 800 words about a topic, either the topic is too narrow (and should be a section within a broader article) or I don't know enough about it yet.
• Check for existing coverage. Before writing a new article, search my own site for the target keyword. If I already have an article on the topic, I expand that article instead of creating a new one. This prevents the duplicate/merge problem from happening in the first place.
• Monthly scans. I run ScanMyPosts monthly to catch any thin articles that slipped through. Sometimes an article seems adequate at publishing time but falls behind as competitors improve their content. Regular scanning catches these before they accumulate.

The Results

Across my 12 sites, addressing thin content has been the most consistently impactful SEO activity. Not keyword research. Not link building. Not technical SEO. Content quality.

On The Turtle Hub alone, fixing thin content (as part of a broader pruning strategy) took the site from 180 articles at 8,000 monthly visitors to 110 articles at 18,200 monthly visitors. Fewer articles, dramatically more traffic. The average quality went up, and Google rewarded that.

The compound effect is what matters most. Every thin article you fix removes drag on your entire domain. Every merger eliminates keyword cannibalization. Every rewrite adds a competitive asset. Over months, the cumulative impact is transformational.
