    Strong opportunities remain in the SEO & digital marketing industry.

    Continuous innovation makes the advertising industry a dynamic sector. Prior to recent memory, advertising was primarily concentrated in print and broadcast media. Significant shifts to internet marketing continue to occur, especially as more brands push toward direct-to-consumer (DTC) advertising options through online search, social media and other digital channels. Furthermore, the proliferation of mobile phones, tablet and desktop computers is expected to continue to see the rise in the digital marketing industry. These shifts are also creating shifts in consumer media consumption behavior. As a result, advertisers are expected to follow consumer demand of digital media.

    In fact, according to the Internet Advertising Bureau (IAB) internet advertising revenues increased nearly 54% from the years 2013 to 2018. Increased demand for industry services is expected to expand the industry further in 2020, created anticipated earnings before interest, taxes, depreciation and amortization (EBITDA) of nearly 7% of overall industry revenues. Even in spite of pandemic pressures, the industry is expected to continue to grow over the coming four years (through 2025), albeit less rapidly than in years past.
