Welcome to the Q&A Forum

Hello, On one of the sites that I manage - http://www.zalikihotel.gr/ , there was a significant decrease in keyword positions over the last 10-15 days. Sample screenshot is attached. Some of the keywords even dropped for 17-18 positions. From the end of April, organic traffic dropped by 30 percent. Website is mobile optimized, so that shouldn't be a problem. In the last 3-4 months, we had traffic increase. Domain authority went up by 3 points after the last index. On-site SEO was completed, and currently I'm focusing on link-building and working on bringing back to life forgotten social media. Does anybody knows what might be the case for this negative affects on our site? Do you think it's a temporary fluctuation or not? Thanks in advance. 8dSBELm.png?1

I have just read http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world and I would like to know which option is the best fit for my case. I have the website http://www.hotelelgreco.gr and every image in image library http://www.hotelelgreco.gr/image-library.aspx has a different url but is considered duplicate with others of the library. Please suggest me what should i do.

Can someone plz tell me why www.hotelelgreco.gr has only 2 internal links in OSE despite the fact that the text content has a plethora of them. Thanks in advance.
