How to Identify and Fix WordPress Crawl Budget Issues for Better SEO in 2024
Are important pages on your WordPress site not getting indexed? Noticing a drop in organic search traffic? You might have a crawl budget issue.
Crawl budget refers to the number of pages search engines like Google will crawl on your site in a given timeframe. Think of it like a monthly budget – you want Google spending its limited crawl resources on your highest-value content, not wasting time on low-quality or duplicate pages.
When your crawl budget is used inefficiently, it can take search engine bots much longer to discover and index your primary content. This not only hurts your search engine visibility, but your overall ability to attract organic traffic and conversions.
In this guide, we‘ll explain how crawl budget issues commonly occur in WordPress and show you how to optimize your site for better crawling and indexing. Let‘s get your SEO back on track!
Understanding Crawl Budget and Its SEO Impact
Contrary to popular belief, crawl budget isn‘t a set number. It varies by site and fluctuates over time based on factors like:
- Site size (larger sites generally have a higher crawl budget)
- Frequency of content updates
- Page speed and server response times
- Quantity of low-value URLs (404 errors, redirects, duplicate pages, etc.)
Think of your crawl budget like any other limited resource. Google‘s sophisticated algorithms allocate a certain amount of attention to your site. The more effectively you capitalize on it, the better your content will perform in search.
Common Causes of WordPress Crawl Budget Issues
WordPress is a powerful, SEO-friendly CMS out-of-the-box. But its flexibility and endless customization options introduce a lot of ways to unintentionally create crawl budget issues.
Some frequent culprits include:
- Duplicate content
By default, WordPress generates separate archive pages for tags, categories, authors, and more. Many of these contain similar or duplicate content which can waste crawl budget.
WordPress sites using aggressive filters and faceted navigation (i.e. eCommerce stores) may produce crawlable URLs with only minor variations.
- Low-quality and thin content pages
Tags, category pages, and other taxonomies with little unique content offer minimal value to users or search engines. Yet WordPress still generates crawlable archive URLs for them.
- Bloated code and slow page speed
Excessive plugins, unoptimized images, and render-blocking JavaScript can drastically increase page load times. Slower speeds limit how quickly search engine bots can crawl your site.
- Improper redirects and dead ends
Redirect chains, loops, and unnecessary redirects all waste crawl budget. So do 404 error pages that aren‘t properly resolved.
- Query parameters in URLs
Session IDs, click tracking UTMs, and other query parameters appended to URLs can signal to search engines that each variation is a unique page. This dilutes crawl budget even if the actual content is the same.
How to Tell If You Have a Crawl Budget Problem
Think you might have a crawl issue? Here are some common signs:
- Pages aren‘t getting indexed or drop out of the index
- Decline in organic search impressions and traffic
- Increase in 404 errors and soft 404s
- Slower crawl rate in Google Search Console
- URLs blocked by robots.txt that shouldn‘t be
- An excessive number of on-site redirects
Of course, these can all have other causes besides crawl budget. But if you suspect an issue, it‘s worth investigating further.
Identifying Wasted Crawl Budget with Google Search Console
To get a clearer picture of how search engines are crawling your WordPress site, look no further than Google Search Console. Its built-in Crawl Stats report provides a wealth of data on your site‘s crawlability.
In Search Console, go to Settings > Crawl Stats. You‘ll see a report with data from the last 90 days on:
- Total number of crawl requests
- Total download size
- Average response time
- Breakdown of crawl requests by response code, file type, purpose, and Googlebots type
Look at the tabs for Response codes and File types. Are search engine bots spending a lot of time on 404 pages or crawling things like scripts and CSS files? Those are likely a waste of your crawl budget.
Also pay attention to the Purpose breakdown. If you see a large number of requests categorized as "Refresh" rather than "Discovery", it could mean Google is recrawling known URLs rather than finding new content.
Clicking the "Host status" button will also show you the historical crawling pattern for your site. Look for any steep drop-offs, as this can indicate technical issues blocking or reducing crawling.
Now that you know how to spot crawl budget problems, let‘s look at how to fix them in WordPress.
9 Tips to Optimize Crawl Budget in WordPress
- Use Canonicals to Consolidate Duplicate URLs
Specify which version of a page you want search engines to index by implementing canonical tags. These simple bits of code tell crawlers which URL is the "preferred" version if multiple pages have identical or very similar content.
If you have an SEO plugin like Yoast or RankMath, you can set canonicals for individual posts and pages. For broader solutions, you may need to add the tags manually or via functions.php.
- Noindex Low-Value Pages
Prevent search engine bots from indexing thin-content pages by adding a noindex robots meta tag. This removes them from search results while still allowing bots to crawl the links on the page.
Good candidates for noindexing include tag archives, internal search results, and user-generated content pages (i.e. WordPress author archives).
You can noindex pages in bulk using the Yoast SEO plugin under SEO > Search Appearance. Select the content types to noindex and it will automatically apply the tag.
- Improve Page Speed and Core Web Vitals
A faster site means search engines can crawl more pages in less time. Improving speed makes your crawl budget go further while delivering a better user experience.
Some quick WordPress optimizations include:
- Implementing caching and lazy loading
- Compressing images and serving them in next-gen formats
- Minifying CSS and JavaScript files
- Using a CDN to reduce server response times
- Limiting external scripts and redirects
Use Google‘s PageSpeed Insights tool to diagnose problem pages and get specific speed recommendations.
- Fix Broken Links and Unnecessary Redirects
404 errors and redirect loops are crawl budget sinkholes. Regularly audit your WordPress site for broken links using a tool like Screaming Frog or Ahrefs. Whenever possible, update broken links to point to a live page rather than relying on a 301 redirect.
You should also minimize redirect chains and remove any outdated redirects. A WordPress redirect plugin like Redirection can help you manage redirects and identify issues.
- Limit Infinite Scrolling and Lazy Loading
Infinite scroll and lazy loading are great for user experience, but can be problematic for SEO if implemented incorrectly. Search engine bots may not be able to access content that requires user interaction to load.
If you do use infinite scroll, make sure each component page has its own static URL that Googlebot can crawl. Avoid lazy loading primary content or linking to it with JavaScript.
- Clean Up Your WordPress Tags and Categories
Go through your site and audit your WordPress tags and categories. Do you have hundreds of tags with only one or two posts each? Lots of empty or thin category pages?
Deleting these can reduce the number of low-value URLs on your site. Consider noindexing any remaining archive pages (see tip #2).
- Audit Content for Keyword Cannibalization
Do you have multiple pages targeting the same or very similar keywords? Spreading your content too thin across numerous pages can dilute its effectiveness and waste crawl budget.
Whenever you have clusters of content all chasing the same queries, consider consolidating it into a single authoritative page. Then redirect the old URLs and update any internal links.
- Submit a Complete XML Sitemap
Help search engines efficiently crawl your site by providing them with an up-to-date XML sitemap. This should include all your important pages and exclude any you don‘t want indexed (like thin tag archives).
If you use the Yoast SEO plugin, it will automatically generate XML sitemaps for your posts, pages, categories, and tags. Just make sure to submit the sitemap URL to Google via Search Console.
- Manage URL Parameters
Does your WordPress site use URL parameters for things like search queries, session IDs, or currency selectors? All those variations can eat up your crawl budget if left unchecked.
In Google Search Console, go to your site‘s settings and use the URL Parameters tool to tell Google how to handle each parameter. Specify whether they change page content and prevent Google from crawling URLs with specific parameters.
Final Thoughts
As you can see, crawl budget is a critical but often overlooked aspect of WordPress SEO. Eliminating inefficiencies frees up search engine bots to spend more time on your valuable content, leading to faster indexing and better overall visibility.
While some crawl budget optimizations are easy to implement, others may require more technical know-how. If you‘re not comfortable editing your WordPress files directly, reach out to a developer for assistance.
Remember, your crawl budget isn‘t fixed. It can grow over time as your site becomes more authoritative. Prove to Google that your content is worth crawling by building high-quality links, improving page experience, and keeping your site fast and lean.
By proactively managing your crawl budget, you set your WordPress site up to perform its best in search engines. A little optimization now can lead to big SEO wins down the line.
