Your customer requires additional Home pages when enabling brands and locales on their Career Site Builder site. Brands are different identities or subdomains that your customer may have for their career site, such as different divisions, regions, or products. Locales are different languages or regional settings that your customer may have for their career site, such as English, French, or German. When enabling brands and locales, you need to create additional Home pages for each combination of brand and locale, to ensure that the content and layout are consistent and appropriate for each audience. For example, if your customer has two brands, Brand A and Brand B, and two locales, English and French, then you need to create four Home pages:
Home - English - Brand A
Home - English - Brand B
Home - French - Brand A
Home - French - Brand B
Maps and site kits are not elements that require additional Home pages when enabling them on a Career Site Builder site. Maps are components that display the location of your customer's offices or job requisitions on a map. Site kits are templates that provide predefined styles, components, and pages for your career site. You can use maps and site kits on any Home page, regardless of the brand or locale, without creating additional Home pages. Reference:

A content page is a type of page that can be created and edited in Career Site Builder, and it is used to display static or dynamic content, such as text, images, videos, or forms. A content page can be linked to other pages or external sites, and it can be customized with different styles, components, and layouts. Some customers may choose to host some of their content pages externally, and link them with their CSB site, for various reasons, such as:
They have existing content pages on their corporate website or intranet that they want to reuse or integrate with their CSB site, without duplicating or migrating them.
They have complex or interactive content pages that require advanced coding or functionality that is not supported by CSB, such as animations, games, quizzes, or surveys.
They have content pages that need to comply with specific legal or security requirements that are not met by CSB, such as data privacy, encryption, or authentication.
Some examples of content pages that are often hosted externally and linked with CSB sites are:
About Us: This page provides information about the company's history, vision, mission, values, and culture. It may also include testimonials, awards, or achievements of the company or its employees.
Diversity and Inclusion: This page showcases the company's commitment and efforts to foster a diverse and inclusive workplace, and to support various groups and initiatives, such as women, veterans, LGBTQ+, or sustainability.
Benefits: This page details the benefits and perks that the company offers to its employees, such as health insurance, retirement plan, wellness program, or employee discounts.
Learning and Development: This page highlights the learning and development opportunities and resources that the company provides to its employees, such as training courses, certifications, mentoring, or career coaching.
Events: This page lists the upcoming events that the company is hosting or participating in, such as webinars, career fairs, or networking sessions. It may also allow candidates to register or RSVP for the events. Reference

Some of the search engine optimization (SEO) leading practices achieved by creating a career site with Career Site Builder (CSB) are:
A new site map is created and delivered to Google and Bing weekly. This will help the search engines index the career site and its pages and jobs more efficiently and accurately1.
CSB supports creating Category pages to host jobs, which helps build SEO value more than specific job postings. This will help the career site rank higher for relevant keywords and attract more candidates2.
CSB uses metadata to help ensure that jobs and pages are search engine-friendly. This will help the career site provide relevant and descriptive information to the search engines and the candidates3.
The other options are not valid SEO leading practices achieved by CSB:
The jobs posted to CSB sites are accessible to website crawlers. This is not a leading practice, but a basic requirement for any career site to be visible to search engines. CSB does not provide any special feature or advantage for this4.
CSB automatically populates hidden text on every page with the keywords provided in the metadata. This is not a leading practice, but a black hat SEO technique that can harm the career site's ranking and reputation. CSB does not support or recommend this5.

Some leading practices when using a link on a career site are:
Populate the title text for each link. This will provide additional information about the link when the user hovers over it, and also improve the accessibility for screen readers and search engines1.
If blue text is used on the site, ensure that it's always used to represent links. This will create a consistent visual cue for the users to identify the links and avoid confusion2.
When a user clicks on the link, immediately display what the user expects to see. This will enhance the user experience and satisfaction by reducing the loading time and providing relevant content3.
The other options are not leading practices when using a link on a career site:
Include multiple links to the customer's corporate site. This will distract the user from the main purpose of the career site, which is to apply for jobs, and also create a cluttered and confusing layout4.
All external links from the career site should open in the same browser window. This will interrupt the user's browsing flow and make it harder for them to return to the career site. It is better to open external links in a new browser tab or window5.
