Search engine optimization (SEO) is the soul of any successful website. But it’s also a lot of work.
Between optimizing keywords, tracking rankings, and analyzing backlinks, it’s easy to get overwhelmed.
Thankfully, there are several SEO extensions for Chrome that can help ease this process. Below, we compare these tools to help you find an SEO extension for your SEO requirements.
What Is an SEO Extension?
An SEO extension is a tool that integrates with your Chrome browser to provide a range of features, such as:
- On-page optimization suggestions
- Keyword research and analysis
- Competitor analysis
- Rank tracking
- Backlink analysis
- SERP Preview
SEO comprises several data points. An SEO extension acts as a central hub to access this data in one place.
Since it works within the browser, you don’t have to switch between multiple tools. Also, most SEO extensions are either free or come at a minimal cost.
So, they’re a cost-effective approach to SEO in real time.
