Welcome to the Q&A Forum

My website is relatively new, January. We climbed steadily to 6th for our search term then overnight rocketed to 1st. This only lasted a week and have been stuck at 9th ever since. When I use the SEO Moz tools our site should theoretically be top...I only joined today btw. Anyway in Google webmaster tools I noticed it said I had duplicate title tags, when I checked to see what the pages were- it was my home page! Google also seems to have cached two versions of our homepage, the root domain and the Default.aspx page. Now I have fixed this canonical linking issue today (using canonical link tag and 301s) so time will tell but has anyone got any first hand experience of this issue? Was it a big factor? Thanks!
