As an AI language model, I am not aware of any specific "Keyword Suggestion Tool v2" since there are many keyword suggestion tools available in the market, and their versions may vary based on the tool provider. However, in general, a keyword suggestion tool is a software application that helps users to identify relevant keywords or search terms related to their topic or industry.

The main purpose of such tools is to assist businesses or individuals in their digital marketing efforts, particularly in search engine optimization (SEO) and search engine marketing (SEM). By using a keyword suggestion tool, marketers can discover new keywords, analyze their search volume, competition, and cost-per-click (CPC) data to optimize their web content, and improve their visibility in search engine results pages (SERPs).

Keyword suggestion tools may offer different features, such as:

1. Keyword research and analysis: The tool provides a list of relevant keywords or phrases that people use to search for a specific topic or product.

2. Search volume data: The tool shows how many times a keyword is searched for in a given period.

3. Keyword competition analysis: The tool assesses the level of competition for a keyword in a specific niche or industry.

4. CPC analysis: The tool displays the average cost-per-click for a particular keyword, which is useful for SEM campaigns.

5. Keyword grouping and categorization: The tool can group keywords based on their relevance, intent, or user behavior, which helps in organizing and optimizing website content.

Overall, a keyword suggestion tool is a valuable asset for businesses and digital marketers, as it helps to optimize their online presence and generate more traffic, leads, and sales.
