How to Merge WordPress Sites Together Without Losing SEO
Are you looking to combine multiple WordPress sites into one? Perhaps you want to consolidate content, rebrand, or merge sites after an acquisition. A successful merger can bring SEO benefits by consolidating authority and eliminating duplicate content. However, if not executed properly, a site merger can result in a loss of traffic and search rankings.
In this comprehensive guide, we‘ll walk through the step-by-step process of merging two or more WordPress sites together while preserving, and even boosting, your SEO. We‘ll cover everything from initial planning to post-merge monitoring. So let‘s dive in!
Benefits of Merging WordPress Sites
There are several scenarios where merging WordPress sites makes sense:
- Consolidating multiple related sites into one comprehensive resource
- Rebranding or changing your domain name
- Acquiring another site or merging with a partner
- Reducing costs and simplifying site maintenance
Beyond organizational benefits, a site merger can be advantageous for SEO by:
- Eliminating duplicate content between multiple sites
- Consolidating link authority and domain power
- Providing a better, more comprehensive user experience
- Reducing cannibalization between multiple sites targeting the same keywords
However, to reap these SEO rewards, the consolidation must be carefully planned and skillfully executed. A misstep could result in broken links, loss of traffic, and a dip in keyword rankings. Here‘s how to get it right.
Step 1: Plan and Prepare for the Merger
Before diving into the technical aspects of a WordPress site merger, it‘s essential to map out a plan:
Audit both sites: Perform a content and SEO audit of the sites to be merged. Identify the high-performing content you want to keep, as well as any low-quality or irrelevant content to be pruned.
Map out URL structures: Decide on the URL structure for the consolidated site. Map out old URLs to their new destinations, identifying any changes or consolidation. This mapping will be important for setting up redirects later.
Determine a redirect strategy: Generally, you‘ll want to implement permanent 301 redirects from old URLs to their new equivalents. This passes authority and avoids broken links. In rare cases, other redirects may make sense.
Set a timeline: Establish a timeline for content migration, URL mapping, testing, and going live with the new consolidated site. Avoid making large-scale changes right before peak traffic periods.
Back up everything: Perform a complete backup of both the old and new sites before beginning the merger. If anything goes wrong, you‘ll be glad to have a restore point.
Step 2: Merge Content
With the prep work complete, it‘s time to bring the separate WordPress sites together:
Export from old site(s): Using the built-in WordPress exporter found under Tools > Export, export an XML file containing all posts, pages, and media from the old sites. If dealing with a large site, you may need to do this in batches.
Import to new site: On the consolidated WordPress site, go to Tools > Import. Install the WordPress importer plugin if needed. Use it to upload the XML file(s) exported from the old sites, mapping authors and importing attachments.
Resolve duplication: With content from multiple sites imported, you may have duplicate posts or pages. Identify the best version of each to keep, then delete the duplicates, being sure to update any internal links to point to the version you‘re keeping.
Update categories and tags: Depending on the sites merged, you may have redundant categories, tags, or custom taxonomies. Consolidate them as needed to provide a good organizational structure and user experience. Use a plugin like Term Management Tools to merge and reorganize.
Audit internal linking: Identify and update any internal links in the imported content that still point to the old sites. An plugin like Link Whisper or Broken Link Checker can automatically identify these for you. Be sure to also update links in navigation menus, sidebars, etc.
Step 3: Implement Redirects
With the content consolidated, the next crucial step is to redirect traffic from the old site(s) to the new destination:
301 redirects: In most cases, you‘ll use permanent 301 redirects. These pass link authority to the new URLs and automatically take visitors to the appropriate new page.
Implement redirects: The simplest method is to use the Redirection plugin. For more advanced needs or non-WordPress sites, you can edit the .htaccess file. Be sure to test redirects thoroughly.
Update canonical tags: If you‘re keeping content at both old and new URLs (generally not recommended), use canonical tags to indicate the preferred URL to search engines.
Step 4: Update External Factors
In addition to redirects, pay attention to external factors that impact SEO:
Update Google Search Console: Verify the consolidated site in Google Search Console. Submit a new sitemap reflecting the updated URLs.
Update backlinks: To the extent possible, update backlinks from other sites to point to the new URLs. Prioritize links with the most SEO value.
Notify Google of site move: In Search Console, use the Change of Address tool to notify Google that your site has moved.
Monitor 404 errors: Keep an eye out for any broken links or 404 errors in Search Console. They may indicate missed redirects or links needing updating.
Step 5: Monitor Traffic and Rankings
The work isn‘t done once the new consolidated site is live. Monitor SEO performance carefully in the weeks and months after the merger:
Traffic: Watch Google Analytics for any dips in traffic, high bounce rates, or other anomalies. Investigate and resolve issues if needed.
Rankings: Monitor target keyword rankings using a tool like SEMrush or Ahrefs. Be on the lookout for any major or sustained drops that could indicate problems.
Crawl errors: Monitor Search Console for any increases in crawl errors like 404s. These can happen if links or redirects get overlooked.
Index coverage: Check that the new pages are getting indexed properly in search engines. You can submit individual pages for indexing in Search Console.
By keeping a watchful eye post-launch, you can identify and resolve any lingering technical SEO issues. Over time, the consolidated site should perform as well or better than the old separate sites.
Common Issues and Troubleshooting
Even with careful planning, a few common issues can pop up when merging WordPress sites. Here‘s how to deal with them:
Redirect loops: If you end up with redirect chains or loops, use a redirect mapping plugin to identify and resolve them. Screaming Frog is another useful tool for this.
Missing images: If images didn‘t migrate properly, you may need to use the Auto Upload Images plugin to import external images and update URLs.
Broken links: A plugin like Broken Link Checker will crawl your consolidated site and identify any broken links that need updating.
SSL errors: Particularly when moving from HTTP to HTTPS, you may hit SSL certificate or mixed content errors. Really Simple SSL can help resolve them.
Ideally, you identified and accounted for potential sticking points during the planning phase. But if issues do arise, swift troubleshooting should resolve them.
The End Result: A Smooth, SEO-Friendly Site Consolidation
Merging multiple WordPress sites into one is no small task. It requires careful planning, a detailed technical process, and diligent monitoring. But when executed properly, a site consolidation can provide both user experience and SEO benefits.
You‘ll simplify your web presence for both visitors and search engines. You‘ll boost content quality by pruning the obsolete and elevating the best. You‘ll enhance authority by consolidating link equity. And you‘ll reduce your own workload by maintaining one stellar site instead of many fragmented ones.
Just remember to follow SEO best practices at each step. Prioritize user experience, not just search bots. Carefully map out redirects, and monitor performance before and after the change.
