A little background on our case.
Our website, ex: http://ourwebsite.com was officially live in December 2015 but it wasn't On-Site optimized and we haven't done any Off-site SEO to it.
In April we decided to do a small redesign and we did it an online development server. Unfortunately, the developers didn't disallow crawlers and the website got indexed while we were developing it on the development server. The development version that got indexed in Google was http://dev.web.com/ourwebsite
We learned that it got indexed when we migrated the new redesigned website to the initial domain. When we did the migration we decided to add www and now it looks like: http://www.ourwebsite.com
Meanwhile, we deleted the development version from the development server and submitted "Remove outdated content" from the development server's Search Console. This was back in early May.
It took about 15-20 days for the development version to get de-indexed and around 30 days for the original website (http://www.ourwebsite.com) to get indexed.
Since then we have started our SEO campaign with Press Releases, Outreach to bloggers for Guest and Sponsored Posts etc.
The website currently has 55 Backlinks from 44 Referring domains (ahrefs: UR25, DR37) moz DA:6 PA:1 with various anchor text.
We are tracking our main keywords and our brand keyword in the SERPs and for our brand keyword we are position #10 in Google, but for the rest of the main (money) keywords we are not in the Top 100 results in Google.
It is very frustrating to see no movement in the rankings for the past couple of months and our bosses are demanding rankings and traffic.
We are currently exploring the option of using another similar domain of ours and doing a complete 301 Redirect from the original http://www.ourwebsite.com to http://www.ournewebsite.com
Does this sound like a good option to you?
If we do the 301 Redirect, will the link-juice be passed from the backlinks that we already have from the referring domains to the new domain? Or because the site seems "stuck," would it not pass any power to the new domain?
Also, please share any other suggestions that we might use to at least break into the Top 100 results in Google?
Thanks.
