WordPress Importer

What is WordPress Importer?

WordPress Importer is the official migration tool developed by WordPress.org. It transfers content from one WordPress site to another using a standard XML export file. The plugin has been available for 16 years and currently holds over 2.0 million active installs. Its rating sits at 3.1 out of 5 stars from 327 total ratings, with 39% 34% one-star reviews. This split reflects a tool that works reliably for many but frustrates a significant minority.

The plugin moves posts, pages, custom post types, comments, custom fields, categories, tags, and authors. It does not handle theme settings, widgets, or plugin configurations. This narrow focus makes it a foundation tool rather than an all-in-one migration solution. Its age and official status mean it remains the default importer inside every WordPress dashboard.

Key Features of WordPress Importer

Who Should Use WordPress Importer?

This plugin suits WordPress site owners who need to move content between installations. It works best for users with basic technical comfort who understand that large exports require manual splitting. The ideal user runs a content-focused site such as a blog, news portal, or small business page. Developers frequently use it as a starting point before running more specialized migration scripts.

The 2.0 million install count shows broad adoption across skill levels. However, the 34% one-star rating and 3.1 average score indicate that users with large files or limited server resources often hit problems. The plugin expects PHP 7.2+ and WordPress 5.2+, which covers most modern hosts. If you run a high-traffic site with thousands of posts, you should expect to break your export into smaller files.

Installation & Setup

Installation happens directly from the WordPress dashboard under Tools > Import. Click the WordPress link, then "Install Now," and finally "Activate Plugin & Run Importer." This process takes under two minutes for most users. Manual installation via FTP is also documented but rarely needed. The setup is beginner-friendly because the dashboard handles everything without command-line access.

Support & Community

Support threads show a 0% resolution rate over the last two months, with 9 open threads and none resolved. This statistic aligns with the plugin being maintained by WordPress.org as a free, community-driven project. The 39% five-star ratings come from users who successfully imported small to medium sites without issues. The 34% one-star ratings typically cite memory errors, blank screens, or failed imports on large files.

The plugin's own FAQ addresses the most common problem directly: out-of-memory errors for large XML files. It recommends increasing PHP memory limits or splitting the export into smaller pieces. Shared hosting users are advised to contact their host for temporary memory increases. The lack of resolved support threads suggests users rely on community forums or the official documentation rather than the plugin's own support channel. For a 16-year-old tool with 2.0 million users, this pattern is expected but worth noting before you depend on it for a critical migration.
