How do you handle localized/country-specific sites? Do you use the URL? i18n

Best practices for localization (l10n) and internationalization (i18n) include: separate content in different folders for each language version, use translation tools and processes integrated with Word or Google Docs, and create separate, language-specific indices.

Is it somehow possible to get a list of pages/sites for a folder?

AEM can create an index (or multiple indices) of your site that are stored in an Excel or Google spreadsheet and served as JSON.

Does the indexing work the same on Google ?

Yes it does. The index will be stored in a Google spreadsheet then.

What is RUM?

A real user monitoring service that checks how fast your site is for visitors in the real world. This give you more accurate performance data than lab results like the Lighthouse score.

How can I integrate Assets from AEM Assets into a website? aem-assets

In AEM projects there are two ways on how you can use AEM Assets or other existing digital asset management solutions, (a) by referencing assets by URL into your AEM page, or (b) to directly copy/paste a high resolution asset into your document from the browsing experience of AEM Assets. The latter option is more common as it is intuitive for authors and has better delivery performance. You can conveniently browse and search AEM assets without leaving Microsoft Word Or Google Docs. For more details, please see https://www.aem.live/docs/aem-assets-sidekick-plugin. In highly controlled environments with complex asset compliance requirements, Option (a) may be more advisable. Please refer to the “External Images” snippet in block party collection. See https://www.aem.live/developer/block-collection#block-party

Do we have an official stance (legally, technically) on using cookies/localstorage to store app state between pages?

AEM does not process Cookies on the server-side. For most applications, it is sufficient (and best practice) to keep application state in the URL, for instance through URL parameters.

Do we currently have something in place to no-index a specific page

You can exclude individual pages from being crawled by search engines by setting the no-index property in the Metadata block. To exclude larger site sections, use the metadata.xlsx spreadsheet.

I’m trying to delete a page, but don’t see the button in the sidekick

To prevent accidential removal of important pages, the unpublish and delete buttons in the sidekick appear only if the corresponding source document has been removed in Word or Google Docs first.

Yes, third-party site search is common for large websites. The most common path for the integration is to use the built in sitemap feature. AEM out of the box indexing provides a built-in option for fast and simple searches for most websites.

Does AEM have an RSS Feed feature we could leverage for our site? If not, are there plans to implement it in the future?

AEM does not publish RSS or Atom feeds out of the box, but the sidekick is extensible, so that it can generate Atom feeds for RSS feed readers from a page index.

How are editors supposed to un-publish pages? I’m not seeing a feature for that in the sidekick, or maybe I’m overlooking something.

To prevent accidential removal of important pages, the unpublish and delete buttons in the sidekick appear only if the corresponding source document has been removed in Word or Google Docs first.

Is it possible to make the embed block you’ve created support embed codes?

Yes, the embed block can be extended to support arbitrary embed codes.

How does AEM handle multiple developers editing the same code at the same time, since the code is partially (?) deployed whenever we rebuild locally? Does it merge changes, or?

As long as you are developing locally, your code stays on the local machine, and only content will be shared. If you commit your code to a GitHub repository, then git will take care of merging changes from multiple developers.

Sometimes there is a significant delay between something showing up inside of the AEM side after being updated in the Word Doc. Any thoughts there?

The Sharepoint API sometimes has a delay of up to three minutes before changes made to your Word document become visible to AEM. If you save the document explicitly with CMD+S (or CTRL+S on Windows) the changes are visible immediately.

There are some concerns I have with all the pages being queried by one index. In some cases, such as in the case of a job post, we have other fields we may want to query and have available in the index. How do you recommend handling this?

AEM supports and suggests creating as many indexes as you need. Best practices include creating one index per language, and creating additional dedicated indexes for common queries.

How does AEM determine what gets published to the URL?

AEM is using the name of the document and folder in Sharepoint or Google Drive to create the page URL on the site. To keep URLs clean, only characters a-z, numbers and the dash are allowed in path names.

What’s the purpose of these three dashes in a document?

Three dashes in a AEM Document indicate a section break. Sections in AEM can be used to structure pages, for instance to change background colors or to trigger animations.

What is fstab.yaml

fstab.yaml tells AEM where the content for your site is coming from. The format is similar to an fstab file in UNIX, but it uses the Google Drive or Microsoft SharePoint sharing URL as the mountpoint.

Links within a project eg. .page and .live URLs are automatically turned into relative links. For authoring purposes it is more intuitive to use absolute links copy/pasted from your browser.

How does AEM handle inheritance and rollouts between multiple sites, both for content and code. Is AEM a good fit for sites with dozens or hundreds of local markets, languages or sub brands. msm

AEM is used in production by global enterprises active in many markets. There is a broad range of facilities to manage code and content centrally and inheriting through multiple tiers into the various websites, locale and brands while still allowing for local adjustments. Content rollout and localization can be tied into existing translation memories that are already integrated into the existing countent source (eg. Sharepoint and GDrive)

It appears that AEM doesn’t really support nested blocks. Is that correct?

AEM blocks cannot be nested to keep things simple and manageable for authors, however there are multiple author friendly ways to created nested structures. One way is to use nested fragements for more complex structures.

Is there a way to reuse content similar to AEM’s content and experience fragments? fragments

Yes, a fragment reference block allows you to embed content from another page in the current page, offering reuse of centrally managed content. The concept of a fragment is used out of the box on most web pages, as the header (navigation) and footers are loaded as fragments.

To better prepare for the importing Workfront/Magento/Marketo blog articles, we need to understand how the import script works and what it is looking for.

The AEM importer is able to import from any existing site and has imported content from Wordpress, Unsplash, Contentful, other AEM instances, and others before. The AEM teams assists you in importing your content from any CMS into Word or Google Docs.

How do I create a staging environment for my site?

AEM is 100% serverless, so you don’t need dedicated environments. If you want to try a new functionality, just create a branch in your GitHub repository.

Does AEM support Workflows? workflows

AEM supports access controls for publishing and delegates the workflows to the content sources used. For Sharepoint (Word and Excel) we recommend Adobe Workfront for document review and approval needs. https://business.adobe.com/products/workfront/main.html

What’s AEM access control model for Authoring? access-control

AEM largely operates on the Access Control model established by the content sources, in Sharepoint and Google Drive there are very robust controls in place covering any imaginable enterprise scenario. Most importantly, both users and system administrators are familiar with those well established controls. It is definitely possible to limit access to certain blocks to users (via the content library) or preventing blocks from being rendered in certain sections of a site. If there is a need to limit access for only parts of a page, it is recommended to go the fragments route and isolate the content with different access control into different documents.

What’s the process for adding the non-indexing code to the AEM pages?

You can specify a metadata property “robots” with value “no-index” in the metadata block of your document.

Can I use AEM with private GitHub repositories?

Yes, AEM has support for private GitHub repositories, but it is important to install the GitHub bot in the repository.

Can XD translate into designs in AEM?

AEM has an experimental integration with Adobe XD that allows using Adobe XD to author content for AEM.

Is there provision in AEM for any sort of “dynamic rendering” (with SSI/ESI “not cached” fragments) – or is the thinking to always rely on pregenerated markup + client code shall some level of PZN be needed for a page?

AEM does not perform any custom server-side rendering. It creates opinionated and optimized markup by default that can then be adjusted for looks, functionality, and personalization on the client. This combination offers the best combination of page performance and ease of development.

What is a good Lighthouse score for an AEM page?

Every AEM site can and should achieve a Lighthouse score of 100. The AEM RUM monitoring helps you understand how fast your site is for your visitors.

We usually see taxonomies being managed spreadsheets or documents representing hierarchical structures and tags being added to the metadata of pages or fragments. External taxonomy systems / APIs can be embedded into the authoring experience as a sidekick plugin. AI based tagging can be implemented both as authoring plugin or directly in the delivery tier, depending on the use case.

Does AEM have something like components?

Yes, they are called blocks in AEM. A block is a reusable part of a page that is rendered differently than standard content.

Do we need to protect AEM against DOS attacks with a WAF on our CDN? waf

The AEM origins are built to withstand regular attacks that occur frequently on the public internet. There is no need to protect the AEM origin from typical scripted or DOS attacks and the AEM security and operations team is continously refining counter measures. Given that the CDN that fronts your website may connect to many other origins, you may still consider WAF services for those origins.

Can we mix content from various AEM sources and other CMSs on the same site? multi-origin

Yes, it is very common for large, mature sites to have a large number of different origins that are tied together on a CDN tier. This allows you to use different AEM projects for different parts/sections of the site and even have that extend to origins that are powered by a different CMS.

Can I have more than one mountpoint in my project’s fstab.yaml? multi-mountpoint
