How to Create Rotating Testimonials Creating rotating customer testimonials is one of the most popular uses for the Blocks Randomizer. Here’s a step-by-step guide: Create or edit the page where you want testimonials to appear (typically your homepage, services page, or dedicated testimonials page) Add the Blocks Randomizer block by clicking the “+” button and searching for “Blocks Randomizer” or typing /random Add your first testimonial inside the randomizer container – you can use Quote blocks, Paragraph blocks, or custom testimonial blocks from your theme Format your testimonial with the customer’s quote, name, company, and optionally add their photo using an Image block Add more testimonials by clicking the “+” button inside the randomizer and repeating the formatting for each customer review Adjust display settings (optional) – in the block sidebar, you can set how many testimonials to show at once if you want to display multiple reviews Publish or update your page – visitors will now see a different random testimonial each time they load the page Pro tip: Use consistent formatting for all testimonials (same heading sizes, image dimensions, text styles) to ensure smooth visual transitions between random selections. How to Set Up Random Call-to-Actions Rotating different call-to-action messages helps you test which messaging resonates best with your audience: Open the page where you want rotating CTAs (homepage, landing page, or product page) Add the Blocks Randomizer block in the section where you want your CTA to appear Create your first CTA using Button blocks, Heading + Paragraph combinations, or custom CTA blocks from your theme or page builder Duplicate and modify – create variations with different: Headline text (“Start Your Free Trial” vs “Get Started Today”) Button colors and styles Supporting copy and benefits messaging Urgency elements (“Limited Time Offer” vs “No Credit Card Required”) Add each variation as a separate block group inside the randomizer Set to display one CTA at a time using the “Number of blocks” setting (set to 1) Monitor performance over time to see which messages drive more conversions Pro tip: Keep the overall design structure similar across variations so the page layout remains consistent, but vary the messaging and emphasis to test different value propositions. Pro tip 2: You can use different UTM values (specifically, utm_content) for your CTA buttons inside the randomizer, this way you can even track using any analytics solution (like Google Analytics, or Fathom Analytics, or Plausible Analytics) which CTA performs better. How to Display Random Products For e-commerce sites, rotating product showcases give equal visibility to your catalog: Navigate to your homepage or shop page in the Block Editor Add the Blocks Randomizer block where you want featured products to rotate Insert WooCommerce or Easy Digital Downloads product blocks inside the randomizer – you can use: Single Product blocks (for individual product showcases) Products by Category blocks (for category spotlights) Hand-picked Products blocks (for curated selections) Configure each product block with your desired layout, show/hide settings for price, ratings, “add to cart” button, etc. Add multiple product configurations – create different product spotlights, categories, or seasonal collections Adjust how many products to display using the randomizer settings Publish your page – products will rotate automatically, giving fair exposure to different items Pro tip: Group related products together or create themed product blocks (e.g., “Summer Collection,” “Best Sellers,” “New Arrivals”) for more cohesive random displays. How to Rotate Banner Advertisements If you display ads, partner logos, or promotional banners, the randomizer helps distribute visibility: Prepare your banner images – ensure they’re all the same dimensions for a consistent layout Add the Blocks Randomizer block to your sidebar, header, or content area where banners should appear Insert Image blocks inside the randomizer, uploading each banner or advertisement Add links to each image by selecting the image and clicking the link icon – set destinations for each ad Include alt text for accessibility and SEO on each image Add multiple banners – upload all your advertisement images or promotional graphics Set display quantity based on your layout (1 for single banner rotation, multiple for ad grids) Publish and monitor – banners will rotate fairly, ensuring all advertisers or promotions get equal exposure Pro tip: Use the same aspect ratio for all banners to prevent layout shifts. Consider adding a Text block below images for additional context or disclaimers if needed. How to Configure Block Display Settings Fine-tuning how many random blocks appear gives you precise control over your content: Select the Blocks Randomizer block by clicking on it in the editor Open the Settings sidebar on the right side of the screen (if not visible, click the gear icon in the top-right) Find the “Number of blocks” setting in the block settings panel Adjust the number using the input field or arrows: Set to 1 for single random block display (great for hero sections, testimonials) Set to 2-3 for multiple testimonials or product showcases Set to 0 to hide the entire block on the front-end (useful for temporarily disabling without deleting content) Preview changes by viewing the page on the front-end or using the editor preview Consider your layout – ensure multiple random blocks fit well within your design at different screen sizes Pro tip: The number you set is the maximum that will display. If you have fewer blocks inside the randomizer than the number specified, all available blocks will show. Using with WooCommerce or Easy Digital Downloads Perfect for e-commerce sites looking to rotate products, promotions, and calls-to-action: Product blocks – Add Single Product, Products by Category, or Hand-picked Products blocks inside the randomizer Product rotations – Showcase different products on your homepage or shop sidebar Promotional banners – Rotate sale announcements and special offers Category spotlights – Give equal visibility to different product categories Cross-sells and upsells – Randomize product recommendations on product pages Example use case: Add and configure a grid block on your homepage, then add a randomizer inside of it, then add 5-10 featured products to the randomizer, set it to display 3 at a time, and visitors will see a different product selection on each visit. Using with Caching Plugins Understanding how caching affects randomization is crucial: WP Rocket: – Random blocks work with WP Rocket’s page caching – Content randomizes when cache regenerates (based on cache lifespan) – For per-visit randomization, add pages to cache exclusions – Consider using shorter cache lifespans for dynamic pages W3 Total Cache: – Compatible with page and object caching – Random selection happens during cache generation – Configure cache expiration based on how often you want new random content – Use fragment caching to cache everything except the randomizer WP Super Cache: – Works with WP Super Cache out of the box – Each cache refresh will select new random blocks – Set appropriate cache timeout for your content rotation needs LiteSpeed Cache: – Fully compatible with LiteSpeed caching – Random blocks cached until cache expires – Use ESI (Edge Side Includes) for more dynamic behavior if needed Cloudflare / CDN: – CDN caching will serve the same version to all users until cache expires – Configure page rules for pages with randomized content – Consider shorter TTL (Time To Live) for dynamic pages Key principle: The Blocks Randomizer performs server-side randomization. Whatever is selected gets cached. New random selection happens when cache regenerates. Using with SEO Plugins The Blocks Randomizer is SEO-friendly since randomization happens server-side. SEO best practices: – Don’t place critical, unchanging SEO content in the randomizer – Use the randomizer for supplementary elements (testimonials, CTAs, featured items) – All variations should be topically relevant to the page’s main purpose – Consider that search engines may index different random variations on different crawls Using with Form Plugins Randomize different contact forms or lead capture forms to determine which one performs better – collects more contacts or leads. WPForms: – Insert WPForms blocks inside the randomizer – A/B test different form designs – Rotate forms for different services or products Contact Form 7: – Add Contact Form 7 blocks to the randomizer – Test different form layouts and field combinations – Rotate forms for different audiences or purposes Gravity Forms: – Add Gravity Forms blocks to random rotation – Test form conversion rates with different layouts – Display appropriate forms based on random selection Formidable Forms: – Compatible with Formidable Forms blocks – Randomize contact forms, surveys, or calculators Using with Membership & LMS Plugins Display dynamic content for members or students: LearnDash: – Randomize course highlights or lesson previews – Rotate student testimonials – Display random course modules or topics MemberPress: – Rotate membership benefits or pricing tables – Randomize member testimonials – Display different membership tier highlights LifterLMS: – Randomize course showcases – Rotate instructor spotlights – Display random learning paths

Normally, if a web page is served by the cache, its content will be always the same until the cache is deleted. By adding the content with the shortcode provided by Content No Cache, you will be able to show dynamic content even on pages served by cache. You don’t need this plugin to exclude the entire page from the cache. This plugin is to exclude a part of the page from the cache. It’s useful if you need to cache a page, but part of that page should not be cached. Imagine you have a page that has this content: Hello this is some text. Another line of text Another line of text Current day: Monday if that page is served by cache, the user will always see: Hello this is some text. Another line of text Another line of text Current day: Monday If you need that the last line of text is always updated, this plugin will help you. The entire page will be served by the cache, but the plugin will get the updated content that you need. How to show dynamic content with full page cache Install Content No Cache Create a new element “Content No Cache” Add to that element all the content that you want to exclude from the cache Copy the shortcode that you will see in the section “Shortcode”. It will look like [content_no_cache id=”3328″]. The parameter “id” is the ID of the content element (in this example 3328). Add the shortcode to the page where you want to display that content. Compatible caching plugins tested with Content No Cache W3 Total Cache WP Fastest Cache WP Optimize Comet Cache Cache Enabler Hyper Cache WP Super Cache LiteSpeed Cache Speed Optmizer WPRocket All of those caching plugins are compatible with Content No Cache. If your favorite caching plugin is not compatible for any reason, let us know it Compatible CDNs Cloudflare BunnyCDN StackPath KeyCDN Fastly CloudFront Main features Ultralightweight plugin. The few lines of code will run only where you add the shortcode. No jQuery, no JS libraries, only a couple of lines of pure JavaScript No database queries, no extra HTTP requests for external assets, no bloat With a few line of ultralight code you can fully cache the page even if you need dynamic content on that page It provides a shortcode, so you can add it everywhere, no matter the builder Tips to speed up the process to get the content Install Freesoul Deactivate Plugins Go to Freesoul Deactivate Plugins => Actions => Content No Cache Disable all the plugins that you don’t need to output the content Example You can see Content No Cache in action visiting the blog post Exclude specific content from being cached. You will see a number that is always different when you refresh the page. But the page is served by full page cache. In the example it’s just a number, but you can output whatever content you want. Possible conflicts Some plugins don’t load the shortcodes during ajax requests. Because Content No Cache retrieves the content through ajax, in those cases the content will not be displayed properly. If you have this kind of issue set the parameter request=”remote”. In this case the shortcode will look like [content_no_cache id=”3328″ request=”remote”] The plugin will retrieve the content in a different way that will be a little slower, but this will solve this kind of conflict.
