Welcome to the Q&A Forum

Agree with Lynn and KempRuge. Hard to give feedback without more info.

Also, someone who I follow for this type of stuff is Gary Vaynerchuk - follow him on FB/twitter and check out his website. http://www.garyvaynerchuk.com/

He is unbelievable.

His mindset and advice will surely help you figure out your social media strategy.

It will depend on your industry and what type of customers you are looking to target. If making the site responsive will cause a strong influx of traffic to the website (i.e. if many of your users are from a mobile device), it may be worth the move. It is important to remember that SEO is a marathon and not a sprint. The long term results of changing your website may be worth the sacrifice of a short lived top ranking.

Whenever the topic of possibly sacrificing current position for future growth potential arises, you must first evaluate how beneficial can a move like this be? Will it attract a market that has been neglected up until now? and if it does drop in rankings how will that affect revenue and are you in the right position to regain your spot on top?

Two important things to remember in preparation of a change like this is:

1. Make backups of your site as insurance.
2. Try to gain as many quality links and boost your social media presence as much as possible before the change. This will help regain the top spot if it does hurt the ranking.

Hope this helped!

I have not heard of one - but if you find one please share with us!  I would love to take a look

One method I've found successful is to leverage what is being discussed on different social media platforms. Through using Google Plus and what is trending on twitter (as well as others), you can discover relevant topics relating to your industry and utilize those topics to create content that is more likely to be shared or visited. See what other companies within your industry are having success posting as an idea.

The Yoast SEO plugin is the way to go, as jStrong and Vadim have mentioned.

First of all, when I search for "fur elise violin and piano sheet music" your pages come up TWICE on page one - results number 6, and 7.

The Viola page comes in at #6, and the Violin at #7.

I would rather have two results rather than one - so consider yourself lucky. (I'm not sure if this is coming up like this on your SERP page, but regardless - your results are personalized for you - I would check www.startpage.com - and I'll bet you see the "real" results (#7 & #8)

One thing that stands out to me about your Viola page which may be why it is beating you Volin page:

It includes "Scorch" files, which the other page does not

Hope this helps

I would add text based content to give your readers, and google, more info about the landing page.

I think the time frame will be different for every site - I believe mostly dependent on how often google crawls your site.  The more authority you have (and the faster google crawls), the quicker they will update.
