Domain authority is a percentage score on your domain name that rates its authority as a trusted and useful source of information and therefore a candidate to rank higher in search engine responses.
Domain authority is a quality that is built over time. It can be improved quickly by dubious methods such as buying backlinks and so on. However the benefits are short-lived and can result in stronger penalties for spamming. It’s not worth the risk. Providing good, solid information in a variety of formats, regularly and at a sensible cost is a good strategy to build domain authority naturally.
List here are the most important factors in building domain authority.
- Domain age – an older domain name (since first registration) is better.
- Domain history – past spamming history lowers authority significantly and for a long time.
- Backlinks – high quality dofollow backlinks (inbound links to your website) are best – important cators include quality, relevancy, genuine, number of nofollow/dofollow links.
- Pagerank – Page Authority, Pagerank and Domain Authority are all related. Helping any one will help all the others and the methods for improvement are similar for all.
- Original content is best – duplicate content may be penalised.
- Quality content – easy to understand, descriptive, variety of formats (text, images, video).
- Add content frequently – frequencydepends on subject matter and budget and you need to strike a balance.
- Interlink articles – use relevant keywords as link anchors.
- No adult or offensive content.
- Bounce rate – lower it by providing links on pages that are irresistible.
- Returning vistors – more returning visitors is better so provide reasons and reminders to return.
- Number of pageviews – (stickiness) visitors viewing more pages is helpful so provide relevant onpage links.
- Traffic sources – the more ways visitors find your sites and greater variety of sources is helpful.
- Time spent – the more time people spend on your site the better.
- Speed – fast response is helpful. Very fast servers are disproportionaly more expensive but there are ways of improving response at low or no cost.
- Crawlability – Reduce crawl errors using information from Google Webmasters.
- Uptime – maximize your website uptime (which implies knowing when and why it’s down).
- Malware – malware found at any time deceases domain authority dramatically for a long while after.
- Redirection – avoid redirections. A few is OK but not too many.
- +1 from Google Plus – work like backlinks. More is best. Don’t buy or spam backlinks as gains are short-lived and may backfire – Google knows if backlinks are genuine or not.
- Authorship – authority of author is helpful.
- Social traffic & user behaviour – tracked for trust/usefulness
- Robots,txt – ENsure robots.txt behaviour has no errors and allows more searching than blocking (Google Webmasters will help here).
- Sitemap – Frequently generated and providing well structured data directly to Google helps a lot.
- Special or unique content will always reign supreme. Content is king.
