  • App Manifest - An App Manifest is a file associated with Native Apps or Progressive Web Apps (PWAs) that outlines the most important aspects of the app, including the app title and the location of critical app files on the server.
  • App Pack - An App Pack is a type of result that Google shows in mobile search results - often at the top. It includes a colorful grid of app logos, with star ratings and names.
  • App Promo Text - Promo Test is an iOS-only piece of app meta data that is meant to highlight time-sensitive information or attractions in the app. It can be updated at any time, so if there are sales, specials or other incentives that are time sensitive, they can be described here. While this can have a secondary impact on ASO by driving more downloads and improving download velocity, the text itself will not help with ranking for particular ASO keywords.
  • App Ranking - App Rankings can reference how an app ranks in a search from the store or it can reference the over-all app rankings from the store, or from a particular category in the store, based on downloads and revenue. These rankings are country and store specific, so they will be different from iOS to Android, and different from one country to another within the same store.

  • Bi-directional Annotation - A system for linking a mobile and desktop version of a page, for use when the page has similar or the same formatting, but mobile-specific design and URL for one page, and a desktop-specific design and URL for the other. The tagging uses a rel=alternate tag from the code of the desktop version of the page, pointing to the URL for the mobile version of the page, and a rel=canonical tag pointing to the desktop URL in the code of the mobile version of the page.


  • Caching - The ability to store and re-use assets in local storage files for a phone, browser or proxy. This allows web pages to re-use certain assets that appear on multiple pages or are accessed on a regular basis, to help the page load more quickly. When locally stored versions of an asset can be used, there is no server-latency associated with the asset.
  • Caching Lifetime/Freshness Lifetime - Describes how long a proxy, phone or browser can keep a particular asset from a web page, before they need to fetch a fresh version of the asset from the server. The longer the freshness lifetime is, the better, because it means that assets that have already been downloaded can be re-used, rather than fetched from the server, cutting down on load time.
  • Canonical Tag - Canonical tags express to Google, the preferred version of a URL when duplication of the page, the page content or the URL are available to crawl. Self-referencing canonical tags can be included in page code to prevent Google over-indexing multiple versions of the same page because parapeters or tracking codes are passed into the URL. Cross-domain canonical tags can reference a page on an entirely different domain that hosts the same content as another page on a different domain. These are often used when a news network publishes a story to multiple websites for local news outlets that are part of a larger conglomerate. In general, it is considered a Best Practice in SEO for all pages to at least have a self-referencing canonical tag, unless the page is canonical to an entirely different page. Canonical tags should be consistent, and should not conflict with other signals, such as server enforced URL rules, sitemaps and internal links. They should also not chained or inconsistent with other canonical tags on the site.
  • Capitalization Normalization - Using server rules to enforce all lower-case rendering of a URL, to ensure that even when links include capital versions of a URL, the URL in the address bar is corrected to lower-case without a redirect. This helps consolidate link signals to a single version of the URL, even when internal or external links to the page are inconsistent.
  • Carrier Data / Carrier Connection / Carrier Network - 'Carrier Data' or a 'Carrier Network' references access internet using a data plan with a mobile carrier, rather than using local Wi-Fi or a cabled connection to the internet.
  • CDN / Content Distribution Network - CDN stands for Content Delivery Network. It is a service that websites can use to create mirror copies of their website assets around the world to remove latency, and make it faster for people from anywhere to access the site.
  • Client-Side Rendering - This is a reference to JavaScript that executes in the browser, rather than on the server. The browser is considered the 'client'.

  • HTML Header & Head Tag - The HTML Header, often just referred to as the head tag is included at the top of the HTML, before the body tag. The head tag contains information that is not displayed directly on the page, but may be displayed in different places in association with the page, including most SEO meta data.
  • HTTP Header - The HTTP Header is a piece of code that is passed before webisite code is passed, in order to share information about the browser, the page and the server, to make sure that things are parsed correctly.
