What is domain authority, and how can you increase it? It’s simply a search engine's ranking (scored on a scale of 1-100) of how trusted your site is compared to the rest of your market. Having a good domain authority comes down to three factors.

Let’s discuss these three factors, and how a having a blog can have positive effects across the board when looking at your site’s domain authority.

Factor 1: The Age of Your Site

Now, just starting a blog will not increase the age of your domain. Sorry. However, spending time or money on content for a blog is more likely to keep your site up to date, and an up to date site ranks better than a rarely updated one.

If you have a single page site built for conversion, you may want to consider adding a blog section to cover updates within your market and news about your own product. This will do a few positive things for your web presence.

Rank for more keywords: Since your blog will add more up-to-date content, you’ll end up ranking for more keywords than a single page or plain ECommerce site. If you’re in a crowded market, this can help you set the edge when it comes to attracting new customers.

By continuing to contribute to your blog, you’ll maximise the age of your site metric, as it will be loaded with content over the course of several years. The best time to write a blog post is yesterday. This is because you want to have a long list of older posts, along with a steady flow of new ones.

Factor 2: The Popularity of Your Site

I mentioned earlier that domain authority is measured on a scale of 1 to 100. The score you need to rank well for a keyword or set of keywords is determined by the competition. The biggest keywords like “how to make money online” are pretty crowded, so you’ll need a score. However, something like “how to make your own mushroom terrarium” is far less crowded.

How popularity affects domain authority: Search engines will look at how many times your site is linked to. The more people are sharing your site, the better. And, the better the authority of the linking source, the more impact it will have on your authority.

The takeaway here is that social media matters. Facebook, for example, has an authority of 100. That means staying active on your site’s social media accounts should be paramount.

How having a blog factors into this: You can’t always post your content across the web. Your social media pages will only reach your followers. However, having a steady flow of content from a blog for your followers to share to their audiences can really do wonders for your traffic.

If you’re more into numbers, take into account this scenario. Let’s say that on any given blog post, 0.05% of your traffic will share the post. On a post with 1350 views, you’ll get 6 or 7 links back to your site.

The traffic grain from that is negligible, but the number of places linking back to you increases your site’s popularity greatly, even if they are NoFollow links.

Now if you posted two articles a week, suddenly those links start adding up, and not only is the traffic from those links starting to accumulate, but you’ll have received over 725 backlinks over the course of a year.

Factor 3: The Size of Your Site

The last key factor is the overall size of your website. Ever wonder why forums always seem to rank pretty high on searches? It’s because they are keyword machines! And the content is generated by users, so there is less work to put in by the site owners.

Forums are great, and the next best thing for large amounts of content is a blog: When I say blog, I mean a steady flow of content, and not necessarily an online diary.

Any site that features scheduled long-form content would fall under this blog word in this case. Each article increases your domain’s size and increases the potential for popularity. Your domain age will, unsurprisingly, come with time.

If your new site is struggling to get attention, you may want to consider the blog style approach. When done correctly, it will help your site expand, and rank quicker than if it was left alone. Then continuing to post to your blog area will help your site get indexed more often.

The Downside of Adding a Blog to Your Site

As you can see, there are a lot of good reasons to add a blog section to your site. On the flip-side, this process does take a continued time investment. If you let your blog area go stagnant for too long, it will do more harm than good. So once you decide to go this route, your hands are tied to it.

It’s up to you to determine if the benefits of better Google ranking and domain authority from a blog page are appropriate for your situation.
