Table of Contents

A comprehensive list of what the best CMS for SEO needs. Use it to choose the best CMS for your website, improve your website, or instruct your web builder.

Need to (re)build a website? Or make the most of SEO? Then use this checklist to choose, order or design the best CMS for SEO.

Great SEO results start with an SEO-friendly CMS (content management system). Many out-of-the -box or even custom CMS’s are not SEO-friendly. Proper configuration and changes are often needed to optimize SEO performance. Unfortunately SEO-professionals are often hired after a new website has gone live, after which it will cost a lot of additional time, money and effort to make the necessary changes.

The best CMS for SEO:

  • Helps search engines to properly read your website (part 1)
  • Helps you to find and optimize content for the right keywords (part 2)
  • Facilitates the sharing of content and social media (part 3)
  • Helps to provide and improve a great user experience (part 4)
  • Provides tracking and optimization opportunities (part 5)

So before building a new website, check if your CMS complies with this checklist of SEO requirements:

1. The best CMS for SEO: technical optimization

1.1 SEO meta tags are supported

SEO uses meta tags to describe the content on the website and make the website more accessible for search engines. Ensure that you can set or modify the following meta tags:

  • Meta descriptions (used to show an excerpt in the search results, max. 156 characters)
  • Meta robots index/noindex (to allow pages to be included or removed from search results)
  • Meta robots follow/nofollow (to direct search engines to the right pages)
  • Meta robots noodp and noydir (to block the DMOZ or Yahoo! Directory to override your meta description)
  • Meta robots noarchive (prevents search engines to cache pages)
  • Meta robots nosnippet (prevents search engines to cache pages and show snippets)
  • Meta robots none (prevents any activity from  search engine)

Note: make sure that the tag for meta keywords is NOT included. This function has been obsolete for nearly three years and will have a negative effect on SEO.

1.2 Content, style and technique are separated

A website is like a house: HTML provides the framework, scripts offer functionalities (like a bathroom), and CSS can be compared to the paint and the wallpaper. These have to be strictly separated in order to have a manageable, smooth running, and crawlable website.

  • JS and (external) CSS are used to separate form and function
  • No use of tables in the design
  • No unnecessary use of code or tags
  • HTML5 is used (instead of Adobe Flash)

1.3 Page loading speed is optimized

A website’s loading speed is important for SEO and a good user experience. Google Speed offers tools and services to measure and improve loading time.

  • Content and style are separated
  • Graphics are preformatted with the right format, compression, and size
  • Pages do not contain unnecessary or hidden content
  • HTTP-requests are minimal
  • The CMS uses a CSS sprite sheet (or tile set)
  • CSS and Javascripts are combined
  • CSS and Javascript are loaded externally
  • CSS scripts are on the top of the page
  • Javascripts are at the bottom of the page
  • Use of asynchronous scripts
  • Proper use of compression
  • Proper use of full page caching
  • Use of a Content Delivery Network (CDN)
  • No Flash or iFrames

1.4 The robots.txt-file is editable

The robots.txt file is a text file that is located in the root of the domain folder. It tells search engines which pages and folders should not be indexed, such as login pages.

  • The robots.txt file should be editable through the CMS

1.5 Duplicate content is avoided

Duplicate content occurs when the the same content is accessible via multiple URLs. This happens often with syndicated content, affiliate websites, or websites with AND without the “www.”-prefix.

  • The CMS does not publish identical content on multiple pages
  • The pages contain a canonical tag

1.6 The CMS generates a dynamic XML sitemap

As the CMS contains the information of all the pages on the website, it’s usually also able to create a sitemap. Sitemaps are used by search engines to find all the pages on a website. Especially websites with a lot of pages (e.g. e-commerce websites, forums, newspapers, etc.) benefit from this feature. An ideal sitemap is made available in XML and is updated automatically.

  • The CMS creates separate sitemaps for different kinds of content (pages, images, videos, mobile data, news, geografical data (KML), etc.)
  • The CMS automatically generates and updates XML sitemap(s)
  • The XML sitemap(s) comply with the protocol.

1.7 Meta tags for languages can be set

Separate content in multiple languages as much as possible. For national websites with multiple languages (e.g. a .ca-domain with English and French content) it’s usually best to separate content in separate folders (e.g. Companies with multiple local websites benefit from publishing to multiple websites at once.

  • Languages should be organised in separate folders
  • ccTLD support, publishing translated content on separate websites with a country-specific domain
  • Pages contain the meta tag rel=”alternate” hreflang=”language

1.8 Templates are used to facilitate creation and optimization

Templates facilitate and speed up the creating and performance of websites.

  • The CMS uses a set of templates to define the look-and-feel pages
  • Templates are optimized for SEO and caching

1.9 The CMS generates SEO-friendly 404 pages

An 404-error occurs when a search engine tries to load a page that does not exist. The website should return a 404-error, signifying that the crawler should try to load the next page. In addition, the website needs to show a 404-page that contains links to relevant pages. This will help search engines as well as visitors to stay on your website.

  • The website returns a 404-error upon loading a non-existant URL
  • A 404-page is shown with every 404-error
  • The 404-page can be customized

1.10 W3C Validation

  • All of the website’s code (HTML, Javascript and CSS) is validated according to the W3C web standards.

2. The best CMS for SEO: content and Copywriting

2.1 Meta titles can be customized

Every page should be able to have their own, unique title. This can be done manually for small websites. For bigger websites with lots of articles or products, the CMS needs generate SEO-friendly titles automatically, using tags. For example, the dynamic title:

  • %class% %holidaytype% to %city%, %country% with %operator% | Travel Bookers

Would generate the titles:

  • Luxury citytrip to New York, United States with Thomas Cook | Travel Bookers
  • Low budget beach holiday to Bahia, Brazil with Star Travel | Travel Bookers
  • Et cetera

What your CMS has to be able to do is:

  • Set an unique <title>-tag on each individual page
  • Control the structure of automatically generated titles per page (for bigger websites)

2.2 Static categories and tags can be used

An SEO-friendly CMS uses a customizable tagging system for websites with many pages. Categories and tags offer the opportunity to automatically create pages with a strong focus on relevant search terms. These topic pages are also good showcases to show your products or authority on a topic.

  • Customize static (sub)categories and tag pages
  • Add an introduction (or SEO copy) at the top and/or bottom of the page
  • Give categories and tags an unique, static URL (e.g.
  • Add pagination with rel=”next” and rel=”prev”-tags
  • Avoid competition between tags and categories with the same keyword focus

2.3 The URLs are SEO-friendly

The CMS needs to create search engine friendly URLs. The URLs need to be able to contain relevant keywords.

  • Generate readable URLs
  • Set unique URLs on a page level
  • Create URLs automatically, based on tags or categories (for bigger websites)
  • URLs need to be static
  • Spaces between words in the URL need to be separated by a hyphen (-)
  • Create URLs without capitals, nor special characters

Note: different page types need a different makeup for their URLs. A vacancy listing should show different information than a product page. If you want to use automatically generated URLs, make sure that you can set them per page template.

Examples of templates that often have multiple pages are:

  • Product page
  • Accessory page (for cross- and upselling)
  • Blogpost
  • Category page
  • Tag past
  • Glossary page

2.8 The website shows breadcrumbs

Breadcrumbs are useful to stress important keywords and emphasize the website structure. Mark breadcrumb-data in the website’s source code, as it will allow search engines to better understand your website and show more information in the search results.

  • The CMS enables the use of breadcrumbs
  • Breadcrumbs are marked with microdata or RDFa
  • The page titles in the bread crumbs can be edited individually

  • Canonical tags can be changed on page level

3. The best CMS for SEO: link building and social media

3.1 Automatic 301 redirects

When the URL is changed, the old URL should automatically be redirected to the new URL. This prevents 404-errors, loss of authority, and improves user experience.
