The Job Alerts Email Template is configured in the E-Mail Notification Templates Settings. This is where you can customize the content and appearance of the email that candidates receive when they subscribe to job alerts on the career site1. You can also specify the sender name, sender email address, subject line, and footer for the job alerts email2.
The other options are not correct places to configure the Job Alerts Email Template:
Command Center: This is where you can manage the career site builder projects, sites, and settings, but not the email templates3.
Recruiting Email Triggers: This is where you can configure the email notifications that are sent to candidates, recruiters, and hiring managers based on certain events or actions in the recruiting process, but not the job alerts email4.
Career Site Builder: This is where you can design and build the career site pages, components, and styles, but not the email templates5.

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 leading practices regarding the timing of the Advanced Analytics implementation are:
Even if Advanced Analytics is configured much later, Advanced Analytics reports contain data beginning when the Career Site Builder career site went live. This means that you do not lose any historical data if you delay the Advanced Analytics configuration1.
Implement Advanced Analytics immediately following the Career Site Builder site go-live. This helps you to monitor the performance and effectiveness of your career site and optimize it based on the insights from the reports2.
The fields the customer wishes to report on do NOT need to be considered until the Advanced Analytics implementation has begun. This is because the Advanced Analytics reports are based on the applicant status set, which is already defined in the Recruiting Management module. You do not need to create any custom fields or mappings for the Advanced Analytics reports3.

To consolidate qualified candidates who were not hired for critical positions in a central location, you can use the following features:
Talent pools: These are groups of candidates that share common characteristics, such as skills, interests, or qualifications. You can create talent pools and add qualified candidates who were not hired to the appropriate talent pools, to maintain a relationship with them and engage them for future opportunities. You can also use the Candidate Relationship Management feature to send targeted email campaigns, invitations, or surveys to the candidates in your talent pools.
Talent Pipeline: This is a feature that allows you to track the progress of candidates through different stages of the recruiting process, such as sourced, contacted, screened, interviewed, or offered. You can create a specific applicant status on the Talent Pipeline, such as "Silver Medalist" or "Backup", and move qualified candidates who were not hired there, to keep them visible and accessible for the recruiters. You can also use the Talent Pipeline to view the candidate profile, history, and notes, and to perform actions such as sending emails, scheduling interviews, or changing statuses.
Creating a Content page on the career site or a field on the application view of the Candidate Workbench are not recommended ways to consolidate qualified candidates who were not hired. A Content page on the career site is a page that displays custom content, such as company culture, benefits, testimonials, or events. It is not a suitable place to store or manage candidate data, as it is public and not integrated with the Recruiting Management module. A field on the application view of the Candidate Workbench is a field that displays additional information about the candidate, such as resume, cover letter, or ratings. It is not a convenient way to group or filter candidates, as it is not searchable or sortable, and it does not allow bulk actions or communications. Reference:

For sites with multiple brands, you can configure different content and category pages, and colors and images, to differentiate them on a Career Site Builder site. Content and category pages are pages that display custom content or job requisitions based on predefined criteria. You can create different content and category pages for each brand, and assign them to different domains or subdomains, to showcase the unique value proposition and opportunities of each brand. Colors and images are visual elements that affect the look and feel of your career site. You can customize the colors and images for each brand, and apply them to different themes or styles, to create a consistent and distinctive brand identity.
Data capture forms and locales are not elements that you can configure to differentiate brands on a Career Site Builder site. Data capture forms are forms that collect candidate information, such as name, email, resume, or consent. You can create different data capture forms for different purposes, such as applying for a job, joining a talent community, or registering for an event, but not for different brands. Locales are settings that determine the language, currency, date format, and other regional preferences of your career site. You can configure different locales for different countries or regions, but not for different brands. Reference:
