My WordPress Site Has Lots of Thin Posts: Should I Link Them Together?

I get this question at least three times a week. A business owner reaches out, panicked because their traffic tanked. They log into their WordPress dashboard, see 400 blog posts written three years ago that are each 200 words long, and wonder if internal linking is the magic bullet.

Here is the reality: linking garbage to garbage just creates a faster path for Google to realize your site isn't helpful. Before you start slapping links around, you need to clean house. I’ve spent the last decade fixing sites that were literally rotting from the inside out because people thought they could "SEO" their way out of neglect.

If you want real SEO improvements, you need a process. Here is how I handle the "thin content" cleanup, starting with my audit checklist.
My Pre-Audit Checklist: Before You Touch a Single Keyword
If you don't track what you’re doing, you’re just guessing. I never start an SEO project without this checklist. If your site doesn't pass these metrics, don't worry about linking yet.
Hosting Response Time: Is your server taking longer than 300ms to respond? If yes, your hosting is a bottleneck. Broken Link Report: Have you cleared out the 404s? Internal linking to dead pages is a waste of crawl budget. Spam Comment Database Size: If you have 50,000 pending spam comments, your database is bloated, which slows down every single page load. Image Compression: Are you serving 4MB hero images on mobile? If yes, your speed score is tanked regardless of your content quality. Hosting and Speed: The Foundation of SEO Improvements
I refuse to work on site architecture until the speed is fixed. You can write the most brilliant, comprehensive guide on the planet, but if it takes five seconds to load on a 4G connection, the user—and Google—will leave.

When you have a massive backlog of thin posts, your database is often bloated. Years of poor hosting choices and neglected plugins mean your server is working three times harder than it should. Before you link anything, move your site to a managed WordPress host https://smoothdecorator.com/how-to-integrate-seo-with-social-media-marketing-stop-building-on-a-foundation-of-sand/ that knows how to cache properly. If your TTFB (Time to First Byte) is over 500ms, your internal linking strategy is like putting a spoiler on a car with no engine.
The Spam Comment Mess: Killing Your Database Performance
One of my biggest pet peeves is opening a client’s database and seeing 100,000 comments, 99% of which are spam. This isn't just an eyesore; it’s a performance killer. Every time a user loads a page, WordPress queries the database. If that database is stuffed with spam, the response time slows down.

You need to handle this immediately:
Akismet: This is non-negotiable. If you aren't running Akismet, you are inviting disaster. It filters out the vast majority of bot-driven garbage before it hits your database. Cookies for Comments: I recommend this to add an extra layer of defense. It forces browsers to "prove" they are human before the comment form submits. It’s light, effective, and keeps the trash out of your wp_comments table. Unlimited Unfollow: If you are dealing with spammy link-backs in your comments section, look into tools like Unlimited Unfollow to ensure you aren't inadvertently bleeding authority to low-quality sites through comment sections.
Clean out the spam, optimize your database tables, and *then* we can talk about content.
Internal Linking vs. Merging: The Strategy
Now, to answer the question: should you link them together? If you have five posts that are 200 words each about "how to choose a lawnmower," don't just link them. **Merge them.**
The "One Quick Example" Rule
Imagine you have three thin posts about "Lawn Mower Blades," "Lawn Mower Oil," and "Lawn Mower Storage." They are thin, they rank for nothing, and they bore the reader.

Don't: Link them together with anchor text like "read more here."

Do: Create one 1,500-word "Ultimate Guide to Lawnmower Maintenance." Take the best bits from the three thin posts, combine them, and redirect the URLs of the old, thin posts to the new guide. This consolidates your authority and actually provides value.

Only link posts together if they are legitimately distinct topics that provide value. If you are just creating links to "keep the reader on the site" without offering a reason to click, you aren't doing SEO; you're just cluttering your own site.
When to Keep Thin Content
Sometimes, thin content is just a placeholder for a specific niche query. If a post serves a clear user intent (e.g., "What is the return policy for [Company Name]?"), keep it. Just make sure the title tag is accurate, the page loads in under two seconds, and it is internally linked from your primary service pages.
Image Compression and Resizing: The Unsung Hero
I once audited a site that had 800 thin posts, all with a single, unoptimized, 12-megapixel stock photo. That’s 800 pages that were essentially broken. Google’s crawlers have a "crawl budget." If your site is heavy, slow, and full of oversized images, Google spends all its time trying to load your images and none of its time indexing your actual text.

Before you start linking, use a tool like Imagify or ShortPixel to compress your entire media library. Resize them to match the actual display dimensions. If your container is 800px wide, your image should not be 4000px wide. Once your images are optimized, you’ll see your Core Web Vitals score jump significantly. That, combined with better content, is where true SEO improvements happen.
Summary Table: Content Cleanup Strategy
Use this table to decide the fate of your thin content. Stop overthinking it and start cleaning.
Post Situation Action Reasoning Multiple posts on the same topic Merge into one pillar post Consolidates authority and rank Old, irrelevant content Delete and 410 (Gone) Prevents Google from wasting crawl budget Short but high-intent utility Update and interlink Improves user experience Spam-riddled comments Purge and install Akismet Improves database speed Final Thoughts: Don't Build on a Foundation of Sand
SEO isn't about gaming Google; it’s about providing a fast, clean, and helpful experience. When you have thin posts, the answer is rarely "add more links." The answer is almost always: "Reduce the noise."

Delete the junk. Merge the related stuff. Fix your hosting. If you find yourself staring at a screen for two hours trying to figure out which keyword to target, you’re doing it wrong. Go check your page speed. Go clear out those spam comments. Go fix those broken links. These are the things that move the here https://bizzmarkblog.com/should-i-remove-or-redirect-broken-links-in-old-blog-posts/ needle. SEO is boring, technical work—if you do it right, you’ll stop worrying about traffic drops and start seeing the steady growth you’ve been chasing.

Start with the hosting, verify your speed with Google PageSpeed Insights, and keep your site clean. Everything else is secondary.
