Search Engine Optimization (SEO)¶
Search Engine Optimization, often abbreviated as SEO, is a digital marketing strategy to improve a website's visibility and ranking in search engine results (e.g., in Google). It involves optimizing various elements on your website, including its content, social sharing, URLs, images, and page speed.

Content optimization¶
To optimize a webpage's SEO, access the page, then go to .
Ghi chú
If you change the title of a blog post or the name of a product, the link to the related webpage is automatically updated. The old link still functions as Odoo creates a 301 redirect, maintaining the SEO.
In-text keywords¶
In-text keywords appear naturally throughout a page’s visible content (titles, headings, and body text) and help search engines determine the topic and relevance of the page. These keywords have a real impact on ranking. They cannot be edited in the optimize SEO pop-up.
Quan trọng
It is strongly recommended to only use one H1 title per page for SEO.
Hình ảnh¶
The size of images has a significant impact on page speed, which is an essential criterion for search engines to optimize SEO ranking.
Mẹo
Compare how your website ranks using Google Page Speed or Pingdom Website Speed Test.
Odoo tự động nén các hình ảnh được tải lên và chuyển đổi chúng sang định dạng Webp. Với định dạng tệp này, ảnh có kích thước nhỏ hơn, giúp tăng tốc độ tải trang và do đó cải thiện thứ hạng SEO. Tất cả hình ảnh được sử dụng trong giao diện chính thức của Odoo cũng được nén theo mặc định. Nếu bạn đang sử dụng một giao diện từ bên thứ ba, có thể giao diện đó cung cấp hình ảnh không được nén hiệu quả.
To modify an image from your website, select the image, click Edit, then go to the Customize tab, and adapt the Format in the Image section.
Quan trọng
Thẻ alt được sử dụng để cung cấp ngữ cảnh cho nội dung mà hình ảnh hiển thị, giúp các trình thu thập dữ liệu của công cụ tìm kiếm hiểu và lập chỉ mục hình ảnh một cách chính xác. Từ góc độ SEO, việc thêm từ khóa thẻ alt vào trường Mô tả là rất quan trọng. Mô tả này sẽ được thêm vào mã HTML của hình ảnh và sẽ hiển thị khi hình ảnh không thể được hiển thị.
Indexation¶
Website indexation is the process by which search engines, such as Google, discover, analyze, and store information about a website's content in their database. Search engine bots, known as crawlers or spiders, visit web pages and follow links to collect data, including text, images, and other media. The purpose of indexation is to make a website's content searchable and discoverable to users. Without being indexed, a website or a specific page on that site will not appear in search engine results, regardless of how relevant or well-designed it is. Indexation is a fundamental step in SEO, serving as the foundation for a website's visibility and organic traffic.
Ghi chú
When you first create your website on Odoo, it will not appear directly in search engine results. Search engines need time to crawl and index it, which can take anywhere from a few days to several weeks. For Google, you can use the Search Console and request indexing for specific URLs, though this does not guarantee faster results. If you have an existing website and are migrating, your previous website may still appear instead of the new one during that timeframe.
SEO impact when migrating your existing website to Odoo¶
In most cases, migrating to Odoo will not negatively impact your SEO. While no platform can guarantee that rankings will remain unchanged, follow these best practices to significantly reduce the risk.
Keep your existing content.
Implement redirects from old URLs to their new counterparts.
Monitor traffic and indexation to make sure that everything is going well, using Google Search Console.
By doing this, you help search engines reindex your site and maintain your visibility in search results.
Ghi chú
It is normal to experience a traffic decrease in the first days.
Prevent a page from being indexed¶
To effectively prevent a page from appearing in search engine results, use one of the following methods:
noindex tag: Access the page's properties and toggle the Indexed switch off.
Ghi chú
This option is not yet available for dynamic pages.
404 or 403: Configure the page to return a 404 (Not Found) or 403 (Forbidden) HTTP status code. These codes signal to search engines that the page does not exist or is inaccessible, leading to its eventual removal from the index.
403: Access the page's properties and toggle the Visibility switch off or unpublish the page.
Google Search Console: Use Google Search Console to request the removal of specific URLs from Google's index.

Prevent a website from being indexed¶
To prevent a website from appearing in search engine results, go to , then in the Website Info section, add a random value in the Domain field. Doing so automatically inserts the following tag into the page source:
<meta name="robots" content="noindex"/>
This tag instructs search engines not to index the site. After applying the change, it may take several days or weeks for search engines to update their results and remove the website.
Example
This can be used to prevent websites from test databases from appearing in search results.
Sơ đồ trang web¶
The sitemap points out website pages and their relation to each other to search engine crawlers.
Odoo generates a /sitemap.xml file, including all URLs. For performance reasons, this file is
cached and updated every 12 hours.
Ghi chú
If your website has a lot of pages, Odoo automatically creates a Sitemap Index file, respecting the sitemaps.org protocol, grouping sitemap URLs in 45000 chunks per file.
Every sitemap entry has three attributes that are computed automatically:
<loc>: the URL of a page.<lastmod>: last modification date of the resource, computed automatically based on the related object. For a page related to a product, this could be the last modification date of the product or the page.<priority>: modules may implement their priority algorithm based on their content (for example, a forum might assign a priority based on the number of votes on a specific post). The priority of a static page is defined by its priority field, which is normalized (16 is the default).
Mẹo
To prevent pages from appearing in a sitemap, go to , and toggle off the Indexed feature.
robots.txt¶
A robots.txt file instructs search engine crawlers which parts of a website they are permitted to
access. Its primary purpose is to:
Prevent overloading the website: By guiding crawlers away from certain sections, robots.txt helps manage server load.
Control access to resources and detailed descriptions: It can prevent crawlers from accessing media files (images, videos), CSS stylesheets, and JavaScript files, and from reading the content (text) of specific pages.
When indexing your website, search engines first look at the robots.txt file. Odoo automatically
creates one robot.txt file available on mydatabase.odoo.com/robots.txt.
Ghi chú
Reputable bots adhere to robots.txt; others may require blocking via Cloudflare on your custom domain.
Edit robots.txt¶
By editing a robots.txt file, you can control which site pages are accessible to search engine crawlers. To add custom instructions to the file, go to , scroll down to the SEO section, and click Edit robots.txt.
Example
If you do not want robots to crawl the /about-us page of your site, you can edit the
robots.txt file to add Disallow: /about-us.
Quan trọng
While robots.txt prevents content from being crawled, it does not guarantee that a page
will not be indexed. A page can still appear in search results if it is linked to from other
crawled pages (indexed by "reference"). Google generally does not recommend using robots.txt to
block webpages that you wish to keep out of search results entirely.
Advanced features¶
Structured data markup¶
Structured data markup is used to generate rich snippets in search engine results. It is a way for websites to send structured data to search engine crawlers, helping them understand your content and create well-presented search results.
By default, Google supports many rich snippets for content types, including Reviews, People, Products, Businesses, Events, and Organizations.
Microdata là một tập hợp thẻ, xuất hiện cùng HTML5, giúp công cụ tìm kiếm hiểu rõ hơn nội dung của bạn và hiển thị nó một cách phù hợp. Odoo triển khai microdata theo đặc tả của schema.org cho sự kiện, sản phẩm thương mại điện tử, bài đăng diễn đàn và địa chỉ liên hệ. Điều này cho phép trang sản phẩm của bạn hiển thị trên Google với các thông tin bổ sung như giá cả và đánh giá sản phẩm:
