If you meant formulas, digital marketing doesn't typically rely on strict mathematical formulas in the same way that physics or chemistry does. However, there are key metrics and calculations that digital marketers use to measure performance and make data-driven decisions. These could be considered "formulas" in a broader sense.

Here are some important digital marketing metrics and how they're calculated:

• Click-Through Rate (CTR): $$\text{CTR}=\frac{\text{Total Clicks}}{\text{Total Impressions}}\times 100\%$$ This shows how often people who see your ad or link actually click on it.

• Conversion Rate (CR): $$\text{CR}=\frac{\text{Total Conversions}}{\text{Total Clicks}}\times 100\%$$ This measures the percentage of people who completed a desired action (e.g., purchase, sign-up) after clicking on your link.

• Cost Per Acquisition (CPA): $$\text{CPA}=\frac{\text{Total Advertising Spend}}{\text{Total Conversions}}$$ This tells you how much it costs to acquire one customer or lead.

• Return on Investment (ROI): $$\text{ROI}=\frac{(\text{Revenue}-\text{Cost of Investment})}{\text{Cost of Investment}}\times 100\%$$ This measures the profitability of your digital marketing efforts.

• Customer Lifetime Value (CLTV): This is a more complex calculation that estimates the total revenue a single customer is expected to generate over their entire relationship with your business. There isn't one simple formula, as it depends on factors like average purchase value, purchase frequency, and customer lifespan.  

If you meant "fundamentals," then these are the core principles and strategies of effective digital marketing. These include:

• Search Engine Optimization (SEO): Optimizing your website to rank higher in search engine results pages (SERPs).  
• Search Engine Marketing (SEM) / Pay-Per-Click (PPC): Running paid advertising campaigns on search engines like Google.
• Social Media Marketing (SMM): Using social media platforms to build brand awareness, engage with your audience, and drive traffic and conversions.
• Content Marketing: Creating and distributing valuable, relevant, and consistent content to attract and retain a clearly defined audience.  
• Email Marketing: Building relationships with leads and customers through targeted email campaigns.  
• Analytics and Data Tracking: Using tools to measure the performance of your digital marketing efforts and make data-driven decisions.
