Our FAQ’s

What is digital marketing?

What does a digital marketer do?

Digital marketing has evolved to the point where an immense array of specialists consult with brands to develop effective strategies or implement programs. If you’re new to digital marketing, or lack experience or resources, you should consider engaging an experienced and versatile digital marketing consultant.

Would my business benefit from digital marketing?

Definitely. Though companies in many business categories continue to approach digital marketing with skepticism, avoiding digital marketing denies your business access to the media the majority of consumers turn to first and at all hours of the day.

What’s the biggest mistake digital marketers make?

Blowing their own horn. Yes, of course, the primary goal of marketing is to create leads. However, in the age of digital media a brand-centric, salesy approach deflects interest in your company. Make your marketing customer-centric. Second biggest mistake: Far too often, digital marketers start and stop. You need to contribute a steady flow of content to the channels you use.

How often should I update my website?

Websites that go for long periods with no updates and new content are unlikely to perform well or support any useful digital marketing objectives. Though a static website technically qualifies as a website it’s bound to be more than a digital brochure that produces little or no leads.

What do I need to know about mobile?

Mobile phones are the most used technology in the world. Most of your prospects spend the majority of their media time—and hours—using a smartphone. Mobile marketing focuses on mobile strategies like messaging, mobile applications, and mobile websites. A brand that ignores mobile marketing is doomed.

What is content marketing?

Content marketing is the creation and distribution of educational and/or entertaining information assets for the purpose of generating brand awareness, traffic, leads and sales. Marketing content is generally free and does not explicitly promote your brand as an ad would.

What’s involved in creating a content marketing strategy?

A content marketing strategy is a plan for building an audience. Elements of content marketing strategy include establishing objectives, audience personas, a value proposition, content marketing mission statement, a buyer journey map, and plans for creating, promoting and analyzing how content marketing assets and programs perform.

Do I need a blog?

Email, social media, search and other elements of your digital marketing mix will depend on delivering useful content. Though video outlets, podcasts, and media galleries present other options, a blog is by far the most used tactic for distributing marketing content on a channel over which you have complete control.

What content should we create?

There can be no all-encompassing answer to this question except to say you should create content buyers will find relevant and useful. Leading candidates include blog posts, articles, ebooks, infographics, microsites, videos, courses, case studies, newsletters, visuals and various forms of interactive content.

What is SEO?

Why is SEO important?

The majority of web traffic is generated by search and those that come by way of search have a greater degree of commercial intent than most other channels.

What is local SEO?

Local SEO is the process of optimizing your online properties to generate traffic from location-based searches. It helps businesses promote products and services to local customers when they need them.

What are keywords?

Keywords are the words and phrases searchers use—usually with search engines—to find relevant pages, images, videos, or any kind of information when looking for answers, knowledge, products, or services. SEO professionals consider keywords and the topics they suggest when optimizing content for search.

What determines search engine rankings?

This question is the source of endless speculation and debate because search engine companies such as Google will not answer it. Experts generally agree rankings are based on relevance and authority, but the factors that determine them are many—and inconsistent. The best way to achieve a high search engine ranking is to create one of the most thorough web pages possible for a specific keyword or topic.

What is PPC?

PPC stands for pay-per-click. Essentially, it’s a way of buying web traffic. Advertisers pay a fee each time one of their ads is clicked. Search engine advertising is the most popular form of PPC, however numerous channels including Facebook now offer PPC ad models.

Why is social media important?

Chances are your audience is active on one or more of the major social networks where billions of people spend time daily. Brands that understand the power of social media marketing and commit resources to it can boost awareness, drive traffic, interact with customers, drive sales, build loyalty, and win advocates.

What is a lead magnet?

A lead magnet is a free offer you make in exchange for an email address (and possibly additional information). The purpose is to inspire prospects to join your email list by offering something of value. Examples include an ebook, guide, report, assessment, cheat sheet, tool, template, webinar, course, or a coupon.

What is a call to action?

A call to action (CTA) is a prompt that instructs the viewer to take a specific action. A call to action is typically written as a command, such as “Buy Now.” In digital marketing a CTA generally takes the form of a button or link.

How long does it take to see results?

Paid digital marketing programs should create results immediately. On the other hand, programs such as content marketing, email list building, and search engine optimization require persistence and patience. You might see some results in a matter of months; however, it’s likely to be six months to a year before you realize some of your traffic and conversion objectives.
