MQL and SQL: definition and key differences in lead qualification
Among the web marketing terms lead generation the most important, the distinction between MQL And SQL is undoubtedly the most strategic. It conditions the transfer of a lead from marketing to sales, and therefore the fluidity of the entire sales chain.
🎯 MQL — Marketing Qualified Lead
A MQL (Marketing Qualified Lead) This is a lead that the marketing team considers sufficiently engaged to warrant further attention. For example, they may have downloaded a guide, visited several pages of the website, or opened multiple emails. However, they are not yet ready to receive a direct sales offer. The MQL is therefore in a phase of education and development.
🏆 SQL — Sales Qualified Lead
A SQL (Sales Qualified Lead) A qualified lead (MQL) is a lead validated by the sales team as ready to be contacted for a sale. They have expressed a specific need, have a budget, and a purchase timeline. In other words, a qualified lead (SQL) is the holy grail of any sales team. The transition from marketing qualified lead (MQL) to SQL is achieved through lead scoring and nurturing.
| Criteria | MQL | SQL |
|---|---|---|
| Responsible | Marketing Team | Sales Team |
| Level of interest | Committed, curious | Purchase intent confirmed |
| Action type | Download, repeated visit | Request for quote, incoming call |
| Next step | Nurturing, targeted content | Initial business contact |
| Average score | 40 to 69 points | 70 points and more |
For example, in the real estate sector, a lead who has viewed several listings and downloaded a buyer's guide will be qualified as an MQL. On the other hand, someone who fills out a form saying "I would like to be contacted within 24 hours" immediately becomes an SQL.
