Welcome to the Q&A Forum

I am trying to understand why my women fashion site has a very low conversion, basically zero apart from some occasional sales (last one a few months ago) There is a lack of organic traffic the to shop subdomain, but what worries me is that (email/social media) campaigns to existing clients who happily buy repeatedly from our brick and mortar store do not generate results, despite using promotion codes etc. Before investing heavily in PPC campaigns etc, I'd like to improve conversion.  Any advice on what can be improved ? PD: link can be found in my profile.

Currently we have a corporate website with general information about a women fashion brand: domain.ae.  This domain has general information about the brand, and links to a blog: domain.ae/blog and an online shop: shop.domain.ae There are much fewer links to the shop compared to the corporate site. In google, often the corporate domain ranks for keywords that would be more relevant to the online shop. I am therefore considering merging the two sites, by basically having the shop on the domain.ae, and adding some more general pages to it, and linking to the blog from there. Will this likely help me in the rankings ? Are there any drawbacks of merging? Any other advice ?
