A form handler is a feature that allows you to use your own forms to post your data to Marketing Cloud Account Engagement. A form handler is similar to a form, but instead of displaying the form on your website, you point your form to Marketing Cloud Account Engagement. This allows you to submit data to Marketing Cloud Account Engagement as well as your own database3. Form handlers are useful when you want to keep the look and feel of your existing forms, or when you want to capture data from multiple forms using one form handler

A good default sales ready lead score is 100, as this indicates a high level of interest and engagement from the prospect. Lead scoring is a way of assigning a numerical value to each prospect based on their behavior and profile, such as visiting your website, opening your emails, filling out forms, etc. The higher the score, the more likely the prospect is to buy from you. A lead score of 100 means that the prospect has met all the criteria you have set for a sales ready lead, such as viewing a specific page, requesting a demo, or downloading a white paper. You can customize your lead scoring criteria and thresholds according to your business needs and goals. For more details -> 12

The best way to track the number of visitors who access a file on a web page that the company does not own on the company website is to use custom redirects . Custom redirects are used to track links such as banner ad clicks, links to third-party sites, links on social media, and access to files hosted outside of Account Engagement. Link clicks appear as activity on a prospect's record. Page actions (A) are not a valid option, as they are used to track and automate actions based on a prospect's page views, not link clicks. Account Engagement form (B) is not a valid option, as it is used to capture and update prospect information, not track link clicks. Account Engagement tracking code (D) is not a valid option, as it is used to track and cookie visitors on the company website, not on a third-party site. Reference: Custom Redirects

According to the Salesforce documentation, when a visitor clicks on a custom redirect with an action of adding a tag, and then fills out a form and becomes a prospect, the following three things will happen to the prospect: A) The prospect activities will show that the form was successfully completed, B) The prospect will be added to the list, and D) The prospect will be tagged. A custom redirect is a trackable URL that can be used to measure and report on the clicks of any online content, such as banner ads, social media posts, or third-party websites. A custom redirect can also have completion actions, such as adding a tag, which are performed when a visitor clicks on the custom redirect. A tag is a label that can be used to categorize and segment prospects. A form is a web form that can be used to collect information from prospects and store it in Marketing Cloud Account Engagement. A form can also have completion actions, such as adding to a list, which are performed when a prospect successfully submits the form. A list is a collection of prospects that can be used for segmentation and email sending. When a visitor clicks on a custom redirect and then fills out a form, the visitor becomes a prospect, and the completion actions of both the custom redirect and the form are applied to the prospect. The prospect activities will show both the custom redirect click and the form submission, the prospect will be added to the list specified in the form completion action, and the prospect will be tagged with the tag specified in the custom redirect completion action. The newly converted prospect will be affected by both the custom redirect and the form completion actions, as they are not dependent on the prospect's previous submissions or activities.
