Best Squarespace Blog Plugins to Boost SEO and Engagement
Squarespace is a fantastic platform for blogging, but if you’ve ever felt it lacks certain features (like a sidebar or related posts), don’t worry—I’ve got you covered. Here are some of the best Squarespace blog plugins out there, specifically for enhancing your blog’s functionality and user experience. Whether you want to improve navigation, grow your email list, showcase related posts, or revamp your commenting system, these plugins can help.
1. Custom Sidebar Plugin
Plugin: Squarespace Blog Sidebar by SQSPThemes (Paid)
Why It’s Great:
Gives you a fully customizable sidebar for your blog, even on templates that don’t support sidebars by default.
A sidebar is prime real estate for adding a newsletter sign-up form, an author bio, social media links, or popular posts.
Update it once, and it shows on all your blog posts automatically.
Real-World Example:
Travel bloggers can use the sidebar to display a quick “About Me” plus a newsletter sign-up to capture interested readers as they scroll your posts.
Food bloggers might feature a small call-to-action to download a free recipe book.
2. Related Posts Plugin
Plugin: Squarespace Blog Related Posts by SQSPThemes (Paid)
Why It’s Great:
Automatically displays a “Related Posts” section at the end of each blog post.
Increases page views by nudging readers to check out more of your content.
Styling is customizable, so it fits your site’s overall look.
Real-World Example:
A fashion blogger who just wrote a post on “Must-Have Summer Outfits” might display related content like “Top Spring Trends” or “Essential Accessories” right beneath the post, keeping readers browsing.
3. SEO Optimization Plugin
Plugin: SEO Space (Free Basic, Premium Paid)
Why It’s Great:
Audits your blog’s SEO performance and flags issues like missing meta descriptions or alt tags.
Provides an actionable to-do list tailored to Squarespace sites.
Helps you systematically improve rankings without needing an advanced SEO background.
Real-World Example:
If you’re publishing a post on “How to Start a YouTube Channel,” the tool can remind you to optimize headings, add target keywords, and ensure images have proper alt tags, making it easier for search engines to understand your content.
4. Table of Contents Plugin
Plugin: Squarespace Table of Contents by Adlytic (Paid)
Why It’s Great:
Automatically generates a clickable table of contents for lengthy blog posts.
Improves readability and user experience—especially useful for tutorials and guides.
Also beneficial for SEO because it encourages readers to stay on the page longer and reduces bounce rates.
Real-World Example:
A lengthy “Ultimate Travel Packing Guide” broken into sections (clothes, gadgets, toiletries, etc.) can have a neat summary at the top, letting visitors jump directly to what they need.
5. Advanced Search & Filter
Plugin: Universal Filter by Squarewebsites (Paid)
Why It’s Great:
Lets visitors filter and search blog posts more efficiently by category or tags.
Perfect for bloggers with large archives who want a better user experience than the default Squarespace search.
Makes it simple for readers to find specific content without endless scrolling.
Real-World Example:
A cooking blog that has hundreds of recipes can provide filters like “Desserts,” “Gluten-Free,” “Vegan,” etc., so readers quickly see relevant posts.
6. Improved Blog Navigation (Pagination or Load More)
Option A: Numbered Pagination Plugin
Replaces “Older/Newer” links with more user-friendly page numbers (1, 2, 3, …).
Great for big archives where readers want to jump directly to page 5 (rather than hitting “Older” five times).
Option B: Load More/Infinite Scroll Plugin
Dynamically loads older posts as you scroll down.
Eliminates the need for page reloads, giving a smoother browsing experience.
Real-World Example:
A photography blog can display dozens of past posts on a single page with an infinite scroll setup, so readers can just keep scrolling to discover more.
7. Email Subscription Forms
Built-in Option: Use Squarespace’s Newsletter Block or Promotional Pop-Up (Included on Business plans or higher)
Why It’s Great:
Grows your email list by prompting readers to subscribe after reading your content.
Connects easily to email marketing platforms like Squarespace Email Campaigns or Mailchimp.
Third-Party Tools: Kit
Offer more advanced design or targeting features (pop-ups, slide-ins, etc.).
Real-World Example:
A personal finance blog can place a sign-up form at the bottom of every post: “Want more money-saving tips? Sign up for my newsletter!”
8. Enhanced Commenting (Disqus)
Integration: Disqus (Free)
Why It’s Great:
Upgrades your comment section with threaded replies, social logins, and notifications.
Encourages more community interaction and discussions.
Real-World Example:
If you share tutorials, Disqus can help readers easily ask follow-up questions, reply to each other’s tips, and keep the conversation going.
9. Google Analytics 4 Integration
Why It’s Great:
Even if you rely on Squarespace’s built-in analytics, adding GA4 gives you deeper insights and better tracking capabilities.
Essential for seeing which posts perform best, where readers come from, and how they navigate your site.
Real-World Example:
A blogger who notices their SEO traffic spikes on certain days of the week might schedule new posts to publish right before the traffic surge for maximum reach.
How to Install Squarespace Plugins (Best Practices)
Check Your Plan: For most code-based plugins, you need at least the Business plan to access Code Injection.
Follow Developer Instructions: Each plugin typically comes with a step-by-step guide. Usually, you’ll add code snippets in Settings > Advanced > Code Injection.
Test Thoroughly: After installing, preview your site on both desktop and mobile to confirm everything looks and functions correctly.
Keep a Plugin List: Maintain a simple doc noting which plugins you’ve installed, where the code is placed, and any specifics. This saves headaches later if you need to troubleshoot.
Monitor Performance: If you add lots of plugins, occasionally check your site speed. Most plugins won’t dramatically slow you down, but it’s wise to be mindful.
