I have a Telephone Services related website (telesystemscorp[dot]com) and doing seo work on this website from last 1 year. In starting having some keywords on Google first page for a limited time. It goes more worse from last year Oct 2013 due to Google's Panguin update.
I'm doing Business Directories, Social Bookmarking, Forums, Article Posting, Business Listings on regular basis. Is it sufficient ? But ranking of website is not back again. Someone suggested me to add an additional blog (blog.telesystemscorp[dot]com) and write for us page ( recently added) for this website and saying if you do article posting on your blog and interlinking the keywords then it will rank back on google. Is it right ??.
I want know that is there any mistake in my on page SEO (Meta Tags) if i change meta tags then is it in correct way ?? or ranking will worst to worst ?? If anybody required my keywords on which i'm doing work will be provided on demand.
Please suggest what's wrong with my website ?? Your advice will be highly appreciated.
