First off, Domain Authority(DA) is a score out of 100 that was developed by Moz and it predicts how well a website will rank on search engines. The higher the DA is, the harder it is to achieve that score. You can use DA when comparing your site to others, or use it to measure your website "strength" over time. If you're just starting out, here's some tips to help you get started. Remove toxic backlinks Don’t wait until you get a penalty, aim to clean up your link profile once a month. Not only will it become more manageable it may give you an advantage over your competitors. Optimise your site speed This will only help a little in terms of SEO, but will make a huge impact on your user experience. All the little points add up to bigger gains, so don’t forget about the little tweaks as well. A common technique is to use a content delivery network (CDN) like cloudflare which will immediately improve your load times. Make shareable content The more your content is ‘shareable’ the more people will share it and the more links you get - simple. Look into creating cool info-graphics and interesting articles. Always include buttons allowing users to share your content easily. …But keep it quality content No need to remind you about this one – but good quality content is king. Write your articles with the reader at front of mind, and the search engine at the back of your mind. Polish your internal linking structure When publishing articles or posts, make the most of on-page SEO and link to other articles throughout your post. Use a variety of anchor texts and try not to use the same one twice in the same post, also avoid making words such as ‘more info’ or ‘here’ clickable. Get your social media in order Having a good social media set up will allow you to get your content in front of people who are interested in what you’re talking about. This goes back to point 3. Share things on social media that others will want to share too, giving you more links and in turn increasing your DA. Have a blog that people want to read This goes back to quality content, but a blog on your site allows you to regularly update your site with fresh and relevant content. Again, if people want to read, they will share it. Work on your User Experience Your site is nothing without your visitors. By making lots of small improvements the results will pay off. So don’t forget about the user when you’re building your site. There is a variety of tools available online to help you with this. Think about off page SEO Once you’ve got the on-page SEO down, its time to start thinking about off-site. Things like guest postings, and commenting on other people’s sites will help. Visit some other sites/forums – join in and leave relevant comments with a link to your site. Be patient – it takes time This isn’t going to change over night, be patient and keep on top of things and you’ll see your DA growing over time.
