I am using all these three utilities/tools everyday and they help me a lot. 1- Semrush - 14 day free agency account trial. IMHO, semrush is one the the best tools to find keywords and to spy on your competitors. http://www.shoutmeloud.com/semrush-coupon-free-trial-account-code.html 2- MOZ free trial for namecheap members - According to your membership status you may get up to 4 months free moz account. And there are other freebies you may use. https://www.namecheap.com/deals.aspx 3- If you have many wordpress sites, you surely know how hard it is to manage them all. There are many great paid services out there like managewp. But what about a neglected one which is totally free and maybe better than all? It is mainwp from sicksubmitter. At first it was a one time paid script then they let it be free. (PS: It has lotsof useful extensions which will take it to another level but you have to pay for them.) http://wordpress.org/plugins/mainwp/. I think mainwp deserves to be mentioned in more detail. I hope to do that in another thread. If you add more, this thread may be a nice help for the community. PS: not affiliated with any of them.
