There are many different factors that affect a page's ranking in Google. Domain authority happens to be one of them. Google doesn't want to rank a website well if it doesn't appear to have the kind of quality that warrants it. This is why it's important to make sure you establish your website as an authority in your industry, with helpful, engaging content and informative blogs.
If you want to help your website increase and maintain good rankings, you need to establish domain authority over your competitors. There are several ways you can do this.
The easiest way to establish authority is to continue to write high-quality, fresh content that provides visitors with as much detail as possible compared to competitors. Naturally keyword-rich webpages and blog posts can largely influence search engines as they crawl your content, indicating to Google that you have more and better information than your competitors. This can result in higher rankings because your content is likely to engage readers while exercising white hat SEO techniques.
The more high-quality websites link back to your website, the more Google will detect that you have a superior presence compared to competitors. You can achieve this by purchasing high-quality links on websites that don't utilize black hat linkbuilding techniques, or by writing and submitting guest posts to blogs that cover industry topics. You can then link back to your website in guest posts, further drawing readers to your website while signifying to Google that you're worth ranking higher.
Another effective means of increasing domain authority is to make sure you have a solid social media presence. Google favors businesses that have well-established Facebook, Twitter, Instagram, and other social media pages linking back to those websites. The more traffic you draw from those sources and attention people give your website, the more Google will notice that you have an advantage over competitors. Subsequently, you can rank higher with better social media. Make sure you share blog posts from your website and interact regularly with your audience, which can significantly improve your efforts.
In addition to online optimization and exposure, there are indirect ways to improve your domain authority via offline branding methods. This includes utilizing offline marketing tactics to increase brand awareness, hosting industry events such as galas and charities, and rewarding frequent users or valued customers with physical prizes.
These are all simply some of the ways you can improve your domain authority to gain favor from Google. Contrary to what you might believe, Google doesn't simply care about basic SEO tactics to help your website rank.
