The biggest difference by far is that it is data-driven. In digital marketing, we measure everything to make the most informed decisions possible. We offer several advantages, such as cost-effectiveness, measurability, flexibility, audience targeting and interactivity. 

Email marketing is a form of direct marketing where businesses send emails to a list of subscribers to promote products or services, build relationships and engage customers. It can include newsletters, promotions, transactional emails and automated email series. Email marketing is highly effective in driving conversions, increasing customer loyalty and improving brand awareness.

Content marketing is a strategic marketing approach that focuses on creating, publishing and distributing valuable, relevant and consistent content to attract and engage a clearly defined target audience. The goal is to drive profitable customer action. Examples of content marketing include blog posts, videos, infographics, e-books and podcasts.

To create an effective digital marketing strategy, you should follow these steps:

1. Define your business goals and marketing objectives.
2. Identify your target audience and their needs.
3. Analyze competitors and marketing trends.
4. Choose the most appropriate digital marketing channels and tactics.
5. Create high-quality and relevant content that engages your audience.
6. Implement, monitor and optimize your campaigns continuously.
7. Measure and evaluate the success of your strategy using relevant KPIs.

The most common types of digital ads include:

1. Display ads: Graphic ads that appear on websites, apps or social media platforms. They can be in the form of images, animations or videos.
2. Search engine ads: Text-based ads that appear in search engine results, often above or below organic results. They are usually paid per click (PPC).
3. Social media ads: Ads that appear on social media platforms, such as Facebook, Instagram, Twitter and LinkedIn. They can be organic or paid and can include images, videos, carousels and sponsored posts.
4. Video advertising: advertisements in the form of short video clips that appear before, during or after videos on platforms such as YouTube, Vimeo and Facebook.
5. Native ads: Ads designed to resemble the surrounding content on a website or in an app. They are often labeled as "sponsored" or "advertising" to distinguish them from editorial content.
6. Email Ads: Ads placed in emails or newsletters, either as banners, sponsored posts or dedicated emails.

Each ad format has its advantages and disadvantages, so it's important to choose the one that best suits your marketing objectives and budget.

The costs of different elements of digital marketing can vary greatly depending on your strategy, objectives and budget. Here is an overview of some common costs for different digital marketing areas:

Search engine optimization (SEO): The cost of SEO can vary depending on whether you handle it in-house or hire an external agency. External agencies can charge monthly fees ranging from a few thousand dollars up to tens of thousands of dollars depending on the scope of services.

Search engine marketing (SEM): The cost of SEM is based on pay-per-click (PPC) or cost-per-thousand impressions (CPM) models. The cost per click varies depending on the competition for the keyword, from a few pennies up to several hundred dollars.

Social media marketing: Organic social media marketing is essentially free, but paid ads can vary in price depending on the platform, target audience and duration of the campaign. The cost per click or per thousand impressions varies, but it is common to budget from a few hundred up to several thousand dollars per month.

Email marketing: The cost of email marketing depends on the platform and the number of subscribers. Many platforms offer free plans for small businesses and then grow in price based on the number of subscribers and advanced features. Prices range from a few hundred dollars per month up to several thousand dollars.

Content marketing: The cost of producing and marketing content varies depending on the format (e.g. blog posts, videos, infographics) and whether you create it in-house or hire freelancers or an agency. Costs can range from a few hundred dollars for a simple blog post up to tens of thousands of dollars
