Search engine optimization (SEO) has become a more complex topic as digital marketing continues to evolve. Some core best practices, such as writing high quality content, will always hold true, but the factors (and the tactics) that impact search rankings most continue to change. Publishers and agencies are constantly searching for new ways to promote their brands, gain visibility, and optimize their sites. To keep track of it all and measure your results, SEO tools are a must.
True SEO comes down to getting the fundamentals right while also making many seemingly small improvements that, when combined, help your content outrank the competition. It’s all about tying together your on-site SEO with your social media efforts, link-building strategy, content marketing, and more to find the right balance that gets results.
