The technical side of SEO starts on the app level. Search engines look at your site as a collection of pages under an umbrella: your . The settings that you set on the app level are less about the identity of your app (with the exception of social media sharing, which we'll cover further down), and more about providing instructions to the search engines, such as:
Which pages to and not to crawl
URLs that have been moved and should be redirected to another URL ()

Some parts of your app's SEO settings can be fairly technical, but if you are not sure if you need them right now, then you most likely don't. We will still cover the basics of each part here.
Your app's SEO settings are found under Settings - SEO/Meta tags:
The first part of your app's SEO settings are the OpenGraph details. This lets you set an identity for your app that social media sites such as LinkedIn, X and Facebook will use when a link to your app is shared. OpenGraph metadata can also affect how your page ranks and is displayed in search engines.
In the example below from LinkedIn, you can see how as soon as a link is typed into a post, LinkedIn fetches the metadata.
This helps you convey a consistent brand identity across both social media and search.
The structure of your page plays a role in determining its ranking. A well-structured page involves organizing your text content into distinct sections, each separated by headers at various levels (such as "<h1> and "<h2>").
By default, the setting to add a tag to a text element is not available, but you can enable it by checking Expose the type of tags for text elements.
Imagine you have a well-researched article in your app, and for some reason, it exists in two different places with slightly different URLs. This situation can create confusion for search engines, as they struggle to determine which version should be displayed in search results.
Canonical URLs are the solution to this problem. They act as a signal to search engines, specifying which version of a webpage should be considered the "primary" or "preferred" one. By using a canonical URL, you help search engines avoid indexing multiple versions of the same content, thereby improving your website's search ranking and overall visibility.
The setting Point URLs to primary domain for better SEO enables a Bubble-defined canonical url tag.
Sometimes, you will want to instruct search engines to not crawl specific pages in your app. For example, if your app has a front-facing index page with other pages like about and privacypolicy you will want those indexed, but you may not want to index backend or admin pages.
Robots.txt (see example) is a small file that Bubble automatically places in the root directory of your app. It contains instructions to search engine crawlers, specifying which parts of the app they are allowed to access and which parts they should avoid.
By default the development version of your app isn't indexed.
Keep in mind that robots.txt is a request to search engines to avoid crawling certain pages. While most search engines will respect this, it doesn't actually stop them from crawling. So this is considered an SEO setting – not a security setting.
Let's say that you want to hide the two pages dashboard and admin from crawlers. You use the Disallow command in robots.txt along with the page name to do so:
Web crawlers work by following links. If they discover your app's domain and its front page, and this page links to a page called about, then the crawler will also index that page.
But what if a page isn't linked to? Or if a page contains dynamic content (such as www.myapp.com/products/running-shoes) – you may link to the product page, but not to every product in your inventory – which is probably the part you want to index.
Keep in mind that for pages with dynamic content, each thing counts as its own separate page, even if they are all loaded on the same page.
Sitemaps are like blueprints for your app that help search engines navigate and understand your app's structure more efficiently. They are essentially XML files that list all the pages within your app even if they are not linked to. Bubble can automatically generate a sitemap for all your pages, and for dynamic pages we will include the things in your database that matches the data type specified on the page.
You can select which pages you want to include in the sitemap. When you check the Expose a sitemap file box, a list of your pages is displayed. Check each page that you want to include.
All the script and meta tags placed in the header will be inserted between the <head> tags on every page of your app, while the scripts added to the body field will be positioned between the <body> tags across all pages.
Adding data to this field will add it to all pages – you can also add it to pages one-by-one in the settings for each page.
A 301 redirect is a permanent redirection method that helps maintain SEO performance when a page moves to a new location. It simply says:
The page used to be here
... and now it's here
... and it's permanent (301)
Bubble offers an easy way to add a before and after URL. The URLs should be the full URL (including the protocol such as https):
From an SEO perspective, this is important for a few reasons:
It helps the search engine find the new page when the old one is missing
It tells the search engine that the content on the new page is not duplicated – it has simply moved
It ensures that any referral traffic still reaches the right content
301 redirects is useful in any case where you need to instruct search engines that a page has moved.
Whenever you rename a page
Whenever you change the slug of a thing you are using as dynamic page content
If you are moving from a non-Bubble framework and your URL structure or domain changes
Wildcards in 301 redirects allow you to dynamically match parts of a URL and redirect them to a new URL structure. This functionality is especially useful when dealing with groups of URLs that follow a consistent pattern, reducing the need to create individual redirects for each URL.
Wildcards are represented by an asterisk (*), which acts as a placeholder for dynamic content in the URL. These placeholders can then be referenced in the destination URL to preserve or reorder the dynamic parts of the original URL.
For example:
From: https://www.example.com/page1/*
To: https://www.example.com/page2
A request to https://www.example.com/page1/anything will redirect to https://www.example.com/page2.
Wildcards can also represent multiple dynamic parts in the URL, which can be carried over to the destination using placeholders like %1, %2, etc., corresponding to the order of the wildcard matches.
To enable and use wildcards in 301 redirects, follow these steps:
Enable Wildcards
Check the box labeled Allow wildcards in redirects for more dynamic urls in your redirect settings.
Note: Exact matches for 301 redirects will work regardless of whether this checkbox is enabled.
Set up the redirect rule
Replace dynamic parts of the source URL with * to indicate wildcards. For example:
https://www.test.com/page1/* -> https://www.test.com/page2
Use placeholders to preserve data
Wildcard matches can be preserved in the destination URL by referencing them using %1, %2, etc.:
%1 corresponds to the first * in the source URL.
%2 corresponds to the second *, and so on.
For example:
https://www.test.com/page1/*/* -> https://www.test.com/page2/%1/%2
Ensure accuracy in the structure
While wildcards allow dynamic matching, the slashes (/) in the source and destination URLs must remain accurate and consistent.
For example:
https://www.test.com/page1/*/* -> https://www.test.com/page2/%2/%1
Query string behavior
URL parameters (the query string) are automatically copied over to the destination URL, regardless of the wildcard setup.
For example:
A request to https://www.test.com/page1/abc?user=123 will redirect to https://www.test.com/page2/abc?user=123.
Bubble lets you upload files to the root directory. There are many use cases for this, but from an SEO perspective the most common use is to upload a custom sitemap .xml file.
Chrome features an integrated SEO audit tool (found in Inspector > Audits). This tool highlights criteria that may impact your search results.
Below is an overview of each criterion and how Bubble apps fare:
Mobile-friendly
Use the responsive engine and set up pages that follow mobile best practices
<meta name="viewport"> tag
