10 Best Squarespace Blog Plugins
Squarespace has a solid blogging system built in.
You can create blog posts, organize them with categories and tags, enable comments, add excerpts, push posts to social media, and build a clean content archive without installing anything extra.
But once your blog starts growing, you may run into a few limitations.
Maybe you want a sidebar. Maybe you want better related posts. Maybe you want readers to filter by topic. Maybe you want stronger SEO guidance, better banner images, cleaner breadcrumbs, or a more useful way to keep people moving through your content.
That is where Squarespace blog plugins can help.
The best blog plugins do not replace your content strategy. They improve the reading experience around it.
Here are some of the best Squarespace blog plugins to consider.
1. Squarespace Sidebar Plugin by SQSPThemes
A sidebar is one of the most useful additions you can make to a Squarespace blog.
Use it for:
Newsletter signup forms
Author bios
Featured posts
Popular posts
Blog categories
Free resources
Product callouts
Affiliate disclosures
Social links
Search
Recent posts
Squarespace 7.1 does not give every blog a traditional sidebar by default, which can make content-heavy sites feel harder to navigate.
The Squarespace Sidebar Plugin lets you add a customizable sidebar to your Squarespace site without rebuilding your blog layout from scratch.
This is especially useful if your blog is part of a larger business. A good sidebar can help turn casual readers into subscribers, buyers, clients, or returning visitors.
Best for: bloggers, educators, service providers, affiliate sites, content libraries, and businesses using content marketing.

2. Related Posts and Products Plugin by SQSPThemes
One of the easiest ways to improve a blog is to help readers find the next useful thing.
A visitor may land on one article from Google, read it, and leave. Related posts give them a reason to keep going.
The Squarespace Related Posts and Products Plugin helps you display related content across your site.
You can use it to show:
Related blog posts
Related products
Related tutorials
Related resources
Related case studies
Category-based recommendations
Tag-based recommendations
This is useful for SEO, user experience, and conversion because it creates better internal pathways through your content.
If you publish tutorials, guides, product comparisons, resource lists, or educational content, related posts can help readers move from one helpful article to the next.
Best for: blogs with a growing archive, tutorial sites, product education, affiliate content, and content-driven ecommerce sites.

3. Universal Filter Plugin by SquareWebsites
If your blog has a lot of posts, filtering can make a huge difference.
Squarespace lets you organize posts with categories and tags, but the default experience can feel limited once your archive grows. Readers may want to filter posts by topic, type, date, difficulty level, industry, or resource category.
The Universal Filter Plugin from SquareWebsites lets you add more advanced filtering, sorting, and search options to Squarespace collections, including blogs.
You can use it to let visitors filter posts by:
Category
Tag
Topic
Date
Post type
Search term
Custom groupings
This is especially useful for large blogs, resource libraries, recipe collections, tutorial archives, directories, and any blog where visitors need to find specific content quickly.
Best for: content-heavy blogs, tutorial libraries, recipe blogs, directories, resource hubs, and educational sites.
4. SEOSpace
Squarespace includes built-in SEO settings, but many site owners still need help knowing what to improve.
That is where SEOSpace can be useful.
SEOSpace is a Squarespace SEO tool that helps users review and improve things like SEO titles, descriptions, image alt text, page settings, keyword opportunities, and other search-related details.
For bloggers, this can be especially helpful because blog traffic often depends on search.
A good blog post should have:
A clear search-focused title
A strong meta description
Useful internal links
Descriptive image alt text
Clean headings
Relevant keywords
Helpful content structure
SEOSpace gives Squarespace users a more guided way to improve these elements.
Best for: bloggers who want more organic traffic, business owners new to SEO, and Squarespace users who want step-by-step SEO guidance.
5. SquareKicker
SquareKicker is not just a blog plugin. It is a broader no-code design extension for Squarespace.
But it can be very useful if you want your blog pages, blog landing pages, category pages, resource sections, or newsletter CTAs to feel more custom.
Use SquareKicker when you want more control over:
Layout spacing
Section design
Animations
Blog landing page layouts
Call-to-action sections
Visual styling
Custom design details
Mobile adjustments
This is useful for designers and site owners who want more design flexibility without writing custom code.
For a blog, SquareKicker can help you make the surrounding experience feel more polished. Think better newsletter sections, stronger resource pages, more interesting blog archives, and more intentional landing pages around your content.
Best for: Squarespace designers, visual brands, content-heavy businesses, and anyone who wants more design control.
6. Disqus Comments
Squarespace has native blog comments, and for many blogs, that is enough.
But if comments are a major part of your site, Disqus may be worth considering.
Disqus can add more advanced commenting features, including threaded conversations, stronger moderation tools, and a more community-oriented commenting experience.
Use Disqus if your blog is built around:
Reader discussion
Community conversation
Opinion pieces
Editorial content
Tutorials with follow-up questions
Active comment sections
If your blog rarely gets comments, you probably do not need it. Native Squarespace comments are simpler and may be better for a quieter site.
Best for: active blogs, community-driven sites, editorial sites, and content creators who want more discussion under each post.

7. Blog Post Breadcrumbs by Schwartz-Edmisten
Breadcrumbs are small navigation links that show where a visitor is on your site.
For example:
Home > Blog > Post Title
On a blog, breadcrumbs can help readers understand where they are and get back to the main blog page more easily.
The Blog Post Breadcrumbs plugin from Schwartz-Edmisten automatically adds breadcrumb navigation to Squarespace 7.1 blog posts.
This is useful for larger blogs where visitors often land directly on a post from Google, Pinterest, social media, or an email link.
Breadcrumbs are small, but they improve orientation.
Best for: larger blogs, SEO-focused sites, tutorial libraries, and websites with multiple content categories.
8. Blog Post Banner Image Styles by Will Myers
Squarespace blog post layouts can feel limited if you want more control over the featured image or banner area.
The Blog Post Banner Image Styles plugin from Will Myers gives you multiple layout options for displaying blog post banner images.
This can make your blog posts feel more polished and visually intentional.
Use this plugin if you want:
Stronger featured image presentation
More editorial-style blog posts
Better visual hierarchy
A more custom blog post layout
Banner styles that feel less generic
This is especially helpful for design-forward brands, photographers, writers, studios, and businesses that care about the visual feel of their editorial content.
Best for: visual blogs, design studios, photographers, lifestyle brands, and editorial-style Squarespace sites.

9. Affiliate Link Genie by Will Myers
If you use affiliate links in your Squarespace blog, you need to handle them properly.
Affiliate links should generally include the right rel attributes, such as sponsored and nofollow, so search engines understand the nature of the link.
Affiliate Link Genie by Will Myers makes it easier to add sponsored and nofollow attributes to links in Squarespace.
This is useful if your blog includes:
Product roundups
Recommended tools
Sponsored posts
Affiliate partnerships
Resource lists
Comparison articles
“Best of” posts
If affiliate content is part of your blog strategy, this plugin can save time and help you keep your links cleaner.
Best for: affiliate bloggers, product reviewers, resource blogs, tool roundups, and sponsored content.
10. Blog Pagination or Blog Navigation Enhancements
Once readers finish a blog post, what happens next?
A strong blog should give them a path forward.
Depending on your site, that might mean:
Previous and next post links
Numbered blog pagination
Related posts
A back-to-blog link
Category navigation
A sidebar with recent posts
A content archive
A newsletter CTA
Squarespace includes some basic blog navigation, but many site owners want more control over how readers move through the archive.
If you want numbered pagination or a more visual way to help readers browse your blog archive, look at our guide here:
How to Add Numbered Pagination to a Squarespace Blog
This kind of navigation matters most when you have a lot of content. If your blog only has five posts, it may not matter. If your blog has fifty, a hundred, or several hundred posts, better navigation can make the archive much more useful.
Best for: large blogs, long-running content sites, tutorial archives, resource hubs, and editorial sites.
Read the Blog Pagination Guide
Bonus: Lightbox Anything Plugin by SQSPThemes
This one is not strictly a blog plugin, but it can be very useful on blog posts.
The Lightbox Anything Plugin lets you open custom content in a popup from a button, text link, image, or other trigger.
On a blog, you can use it for:
Newsletter signup forms
Content upgrades
Lead magnets
Resource downloads
Author bios
Video tutorials
Bonus examples
Contact forms
Product demos
For example, you could write a tutorial and include a button that says “Get the checklist.” When the reader clicks, the signup form opens in a lightbox without sending them away from the post.
That can be a cleaner experience than forcing every call to action directly into the article body.
Best for: lead generation, content upgrades, newsletter growth, and tutorial-based blogs.
Which Squarespace Blog Plugin Should You Use First?
It depends on the problem you are trying to solve.
If your blog feels hard to navigate, start with the Sidebar Plugin, Related Posts and Products Plugin, or a filtering/navigation plugin.
If your blog needs more search traffic, look at SEOSpace and clean up your titles, descriptions, headings, internal links, and image alt text.
If your blog looks too plain, look at SquareKicker or Blog Post Banner Image Styles.
If your blog has an active community, consider Disqus.
If your blog uses affiliate links, Affiliate Link Genie is worth a look.
The best plugin is not the one with the most features. It is the one that removes the clearest limitation on your site.
Final Thoughts
Squarespace is already a strong platform for blogging, especially if you want a clean site that is easy to manage.
But as your content grows, your blog may need more structure, better navigation, stronger SEO support, or a more polished reading experience.
That is where blog plugins can help.
Start with the basics: write useful posts, organize them with categories and tags, add clear titles and descriptions, and link related content together.
Then add plugins where Squarespace stops short.
