Understanding the Tools: Astra + Spectra

If you’re wondering how to build faster WordPress SaaS pages with Astra and Spectra, it all starts with knowing what these tools actually are, and why they’re so great for your project.

What is the Astra Theme?

Astra is one of the most popular free themes for WordPress, and for good reason. It’s lightweight, meaning it loads fast, which helps improve your page speed and overall site’s performance. That’s great news for your visitors and even better for your rankings on search engines like Google.

One of the best parts? Astra comes with ready-made SaaS templates that you can use right away. Whether you’re building a homepage, pricing page, or landing page, Astra makes it easy to design a clean and professional web page without touching any code.

It’s also SEO-friendly, supports Google Fonts, and works perfectly across all mobile devices.

What is Spectra?

Spectra is a free plugin that adds powerful design blocks to the WordPress block editor (Gutenberg). You can think of it as a block-based page builder that helps you create beautiful layouts, all visually, just drag and drop.

What makes Spectra stand out is its collection of prebuilt SaaS blocks, like feature grids, testimonials, pricing tables, and more. These blocks are designed with performance in mind, so they won’t slow down your web server or bloat your JS and CSS files.

Steps to Building WordPress SaaS Pages with Astra + Spectra

Here we’re going to show you just how incredibly simple it is to build a professional, high-performing SaaS website using the power of WordPress, combined with two fantastic tools: Astra and Spectra PRO. Get ready to demystify website design and bring your vision to life without the headache!

Step 1: Set Up WordPress

Before anything else, you need a WordPress website up and running. If you already have a website, it’s great. But if you haven’t set one up yet, don’t worry, it’s easier than it sounds.

• Choose a Hosting Provider: Select a reliable WordPress hosting provider like DreamHost, Hostinger, WP Engine, or Kinsta. These services are known for speed, security, and helpful support.

• Install WordPress: Most hosts offer a 1-click install. Just follow the setup wizard to install the latest WordPress version. This will give you access to your WordPress dashboard.

• Set Up Domain Name System (DNS): If you already have a domain (like www.yoursaas.com), you’ll need to connect it to your host. You do this by updating your DNS settings where your domain is registered (e.g., GoDaddy, Namecheap).

• Access Your WordPress Dashboard: Once the install is complete, go to the WordPress admin dashboard and log in using your admin credentials.

Step 2: Install Astra Theme

Now that WordPress is ready, it’s time to install the Astra PRO theme, a lightweight, flexible theme that’s perfect for SaaS websites.

• Log in to WordPress: Go to your dashboard at yourdomain.com/wp-admin.

• Navigate to Themes: Click on Appearance ⟶ Themes in the sidebar.

• Search for Astra: Click the Add New button at the top, then type “Astra” into the search bar.

• Install and Activate: Once you see the Astra theme, click Install, then hit Activate to make it live on your site.

Why Astra?

• It’s designed for speed and clean code, which means faster load times.

• It works perfectly with page builders like Spectra.

• You get access to professional templates, including options built specifically for SaaS businesses.

Step 3: Install Spectra Plugin

Once your Astra PRO theme is active, it’s time to level up your WordPress site with Spectra PRO, a powerful block-based builder that works hand-in-hand with Astra to create fast, high-converting SaaS websites. Think of it as your design superpower, offering prebuilt SaaS blocks, professional templates, dynamic content support, and a performance-first mindset.

If you’ve invested in the Essential Toolkit, you’ll already have access to Spectra PRO. Here’s exactly how to install and activate it:

• Log in to your Brainstorm Force account

• Find the Spectra PRO plugin (under Essential Toolkit if that’s what you bought)

• Download the ZIP file to your computer

• Copy your license key, you’ll need this in a moment

Step 4: Activate Essential Toolkit

Now that you have the toolkit in hand, it’s time to put it to use. Here’s how to activate both Astra PRO and Spectra PRO on your WordPress site:

Upload and Install the Plugins: Here’s how you can do it:

• In your WordPress dashboard, head to Plugins ⟶ Add New ⟶ Upload Plugin.

• Upload the Astra PRO and Spectra PRO ZIP files you downloaded from your Brainstorm Force account.

• Click Install Now, then Activate for both plugins.

Activate Your Licenses: Now, it’s time to activate your licenses:

For Astra PRO:

• Go to Appearance ⟶ Astra Options.

• Click on Activate License, paste your license key, and hit Activate.

For Spectra PRO:

• Navigate to Spectra ⟶ Settings.

• Under the License tab, paste your license key and click Activate.

Once both licenses are active, you’ll unlock all the powerful premium features, professional templates, performance enhancements, advanced styling options, and more.

Step 5: Customize Astra and Spectra Settings

To begin customizing Astra, go to Appearance ⟶ Astra Options or simply head to Astra ⟶ Dashboard from your WordPress sidebar. Here, you’ll unlock a range of pro modules that let you personalize every aspect of your WordPress website.

You can enable extra modules such as the Header/Footer Builder, Typography, Spacing, Colors & Backgrounds, and more. These tools allow you to build a polished and responsive layout that adapts well across all screen sizes, including mobile devices.

You’ll also find Custom Layouts, which are incredibly useful for adding sticky headers, and banners, perfect for enhancing your SaaS site’s user experience and branding. These advanced layout tools not only give your web page a unique look but also help with site performance and navigation.

Next, move over to the Spectra ⟶ Dashboard. This is your control center for the Spectra PRO plugin.

Here, you’ll see all the powerful block options available, like Pricing Tables, Info Boxes, Feature Grids, Popups, Testimonials, and more. These blocks are especially designed for performance and visual impact.

To keep your site’s speed high and avoid bloating your website with unnecessary JS and CSS files, it’s smart to enable only the blocks you actually need. This selective activation helps in optimizing both the front-end and back-end of your WordPress site.

With these customization tools now enabled and configured, your foundation is set for building a fast, beautiful, and scalable SaaS website using Astra and Spectra.

Step 6: Use Astra Premium Starter Templates

Now that your Astra and Spectra PRO plugins are installed and activated, it’s time to move on to one of the most exciting steps: setting up your starter template. This makes the website-building process incredibly easy and fast, especially for beginners or busy entrepreneurs.

To get started, go to your WordPress dashboard and install the Astra Premium Starter Templates plugin. 

You can find it by navigating to Plugins⟶ Add New, then searching for “Starter Templates.” Click Install and then Activate. 

Once activated, this plugin integrates seamlessly into your dashboard and gives you access to a vast library of ready-made website designs.

Step 7: Choose a Page Builder

Now, choose your preferred page builder. 

For this walkthrough, we’ll use the default WordPress block editor, which works perfectly with Spectra. The Starter Templates plugin will now sync and update the available template library to show the latest designs.

Use the search bar and simply type “SaaS.” You’ll instantly see a variety of beautiful, professionally designed templates optimized specifically for SaaS websites. 

These templates include everything from homepage layouts and feature sections to pricing tables, testimonials, and contact pages.

Some templates may not be perfectly filtered (like an occasional e-commerce layout slipping through), but you’ll still find plenty of relevant and stunning options such as:

• SaaS hub companies

• App landing pages

• Blockchain and tech-focused designs

Just pick the one that best aligns with your business offering. For example, if you’re promoting a mobile app, select the SaaS App template. Once you’ve made your choice, you can preview it in full. If it looks good, click to import it.

Make sure you’ve entered your Essential Toolkit license key earlier if prompted again; just paste it to unlock all design elements. After confirming, the template will be imported along with all necessary settings, including pages, images, and layouts.

Step 8: Customize Your Pages

With your starter template installed, it’s time to make your website uniquely yours. Astra and Spectra make this process incredibly user-friendly, even if you’re not a designer or developer.

Start by heading over to the WordPress block editor. You can do this by navigating to the page you want to edit and clicking the “Edit Page” option at the top.

Now let’s break down how you can personalize your page:

• Edit Headlines and Text: Replace the placeholder text with your SaaS business name, tagline, or product messaging. Tools like ChatGPT can help you write engaging, SEO-optimized content for each section.

• Update Images: Click on image blocks and choose from your media library or upload your own high-quality visuals. This is key for creating a polished and professional look.

• Customize Style: Spectra’s settings allow you to change fonts, colors, button styles, and background elements to match your brand identity. You can also apply global styles for consistency across the site.

• Rearrange or Add Sections: The block editor is completely drag-and-drop. Move content sections up or down, delete parts you don’t need, or add new blocks like FAQs, testimonials, or videos.

• Use Spectra PRO Blocks: Take advantage of advanced Spectra blocks like Pricing Tables, Feature Grids, Info Boxes, and Call-to-Action sections. These pre-styled elements make your SaaS offer clearer and more compelling.

• Optimize Performance: Spectra allows you to enable only the blocks you use. This keeps your site lightweight, loads faster, and helps with Core Web Vitals scores, great for SEO and user experience.

Once you’ve made all your edits, simply click Update. Your changes go live instantly. Within minutes, you’ll have a fully customized, high-performing SaaS website that reflects your brand and speaks to your target audience.

Step 9: Utilize Dynamic Content

To create a truly scalable SaaS site, you need to move away from static pages for each product or feature. Instead, use dynamic content to make managing multiple product feature pages effortless.

Here’s how to do it:

• First, install the Advanced Custom Fields (ACF) plugin by going to Plugins ⟶ Add New, then search for “Advanced Custom Fields”, install, and activate it. ACF is free, but if you want to create field groups and custom taxonomies, you’ll need the Smart Custom Fields (SCF) PRO plugin, which offers enhanced functionality for advanced content structuring.

• Then, create a custom post type for your product features (e.g., “Features”):

• Navigate to your custom post type plugin

• Create a new post type called Features (singular: Feature).

This ensures each feature can be added individually from the dashboard and will automatically follow a structured format.

Now, define your custom fields:

Go to ACF ⟶ Field Groups ⟶ Add New.

Name the group (e.g., “Feature Fields”).

Add fields like:

• Heading 1 (Text)
• Heading 2 (Text)
• Text 1 (Textarea)
• Text 2 (Textarea)
• Image 1 (Image)
• Image 2 (Image)
• CTA Button Text and Link (optional)

Make sure you assign this field group to display when the post type equals Feature.

Once saved, you’ll now see a “Features” menu in your dashboard. From here, you can Add New feature entries by simply filling in the form fields, no design or layout work required each time.

Step 10: Build and Apply Templates

Now that you’ve structured your feature data using ACF, it’s time to design a reusable template that automatically populates each feature’s page with its unique content.

Open Astra’s Site Builder

• Go to Astra ⟶ Site Builder. This tool lets you create headers, footers, hooks, and most importantly, single post templates.

Create a New Single Template

• Click on Single and then click Add New.

• Name it something like “Product Feature Template.”

• Set the display condition to target the Feature post type.

Build the Template

• Now use Spectra blocks and dynamic content options to structure the layout:

• Use the Featured Image block to display the product visual.

• Insert headings and text blocks and link them to ACF fields using dynamic tags.

• Use Spectra’s Image, Call-to-Action, and Grid blocks where needed, all powered by your ACF fields.

• You can even structure it to replicate an existing page layout from your template by copying and pasting blocks, then connecting them to dynamic content.

• Once the layout is in place, save and publish the template. Any new Feature post you publish will automatically use this design, pulling content from your ACF fields and rendering it beautifully on the front end.

Step 11: Finalize and Launch

With your templates and dynamic content system ready, the final step is to polish everything and go live confidently:

Test Pages for Speed & Responsiveness

• Use Google PageSpeed Insights, GTmetrix, or Lighthouse to test your site’s performance.

• Optimize images and minify CSS/JS where needed. Astra and Spectra are already performance-focused, so you’ll likely start strong.

Ensure Mobile & Cross-Browser Compatibility

• Check how your templates render on desktop, tablet, and mobile.

• Make sure clickable elements (like CTA buttons) are easily tappable.

Improve Usability and SEO

• Use AIOSEO, Rank Math or Yoast SEO to configure your titles, meta descriptions, and schema.

• Ensure every product feature page has a unique title and URL.

• Double-check heading hierarchy (H1-H6), alt text for images, and internal links.

Back Up & Secure Your Site

• Use tools like BlogVault or UpdraftPlus to automate backups.
• Add security plugins like Solid Security, or Wordfence for basic protection.

Launch!

• Once satisfied, remove any demo content.
• Announce your launch across your marketing channels.

Optionally, enable a Coming Soon or Maintenance Mode plugin to manage visibility during final tweaks.

Additional Considerations when Using Astra + Spectra

While Astra and Spectra provide a powerful combination as your WordPress theme and website builder, respectively, there are several important considerations to ensure you maximize your site’s potential, especially regarding website speed, performance, and scalability.

Explore Advanced Features and Integrations

Both Astra and Spectra come with a wealth of advanced features even in their free versions, but as a WordPress user, it’s worthwhile to keep exploring beyond the basics. Astra is known as one of the best WordPress page builder compatible themes because it plays well with multiple builder plugins and offers extensive customization options without bloating your site with unnecessary CSS and JavaScript files.

Depending on your SaaS product’s requirements, consider adding:

• Membership functionality if you want to restrict content or provide tiered access.

• Ecommerce website features using WooCommerce or other plugins for selling subscriptions or services.

• Automated integrations such as email marketing, CRM, or analytics tools.

These enhancements let you build a truly professional and fully functional web application tailored to your business needs.

Optimize Website Speed and Performance

Website speed and page load time directly impact both user experience and your rankings in Google Search Console. Astra is specifically designed to be lightweight, meaning it loads minimal CSS and JavaScript files by default, preserving precious server resources and reducing page load time.

To further optimize:

• Use a content delivery network (CDN) to serve your site’s assets globally and reduce latency.

• Enable browser caching so repeat visitors experience faster load times.

• Choose a reliable hosting provider with strong uptime and fast server response times.

• Regularly audit for broken links that could hurt SEO and user experience.

• Consider security layers like web application firewalls to protect your site from malicious traffic.

By keeping your site lean and fast, you improve overall website performance, enhancing your chances to rank higher in search results for your relevant keywords.

Leverage the Flexibility of Astra and Spectra

Many WordPress subject matter experts recommend Astra because it supports most popular page builders such as Beaver Builder, Elementor, and others, allowing you to build a website exactly the way you envision it. 

However, using Astra with Spectra specifically gives you a streamlined workflow with just a few clicks to customize layouts, styles, and dynamic content without writing code.

Unlike other page builders that may load excess JavaScript files or impact site speed, Spectra emphasizes efficiency and only enables the blocks you use. This targeted loading keeps your own website fast and responsive, a crucial factor for retaining visitors and converting them into customers.

Maintain and Scale Your SaaS Website

Building your SaaS site is just the start. Ongoing maintenance is key:

• Regularly check your site’s speed and optimize resources.

• Use tools like Google Search Console to monitor performance and fix any issues.

• Ensure compatibility with new WordPress versions and plugin updates.

• Monitor for broken links or outdated content that could affect SEO.

With Astra and Spectra’s scalable design, you can easily expand your site as your business grows, whether that means adding new features, launching an ecommerce website, or integrating third-party services, all while maintaining fast page load times and smooth user experiences.
