Welcome to the Q&A Forum

We are in the business of selling home and commercial light fixtures for about 10 years now. Our website is a very large ecommerce website with more than 40K pages including category, sub-category and product pages. We have been getting decent organic traffic mostly from highly competitive keywords and also from product/solution specific long tail keywords. Recently when Google changed the EMD algo we have seen a dip in the traffic (say about 60%). I can't be so sure that this is because of EMD update, but it started happening only after this update. There has been a rank drop from 1st page to 2nd page, decrease in no. of keywords driving traffic, decrease in no. of pages driving traffic, all these things have an negative impact on our organic revenue. I know that our back link portfolio is bad and the reason behind this is the SEO companies that we previously worked with, Thanks to them for this sloppy work. Other than back links, Is there anything fundamentally wrong on our website. Here is the URL http://bit.ly/QVFHgr
