Links are naturally do follow in nature but if you want Google ont to pass the link juice to some links then you add rel='no follow'

hope this helps!

There are 100s of areas that search engines look in to before ranking any website against any key phrase.  Meta keyword tag is one of the areas which are considered as less important.

Google have clearly recommended not to use it and they do not use this as a ranking factor but as far as the Bing is concern they do use it as a ranking signal but still this does not land in important ranking factors.

There are no significant reasons why I do not use it because there are tools which can indicate competitors that what keywords i am focusing, so saying that I am not using so that my competitors didn’t get to know what I am up to is silly!

I think Meta keyword tag is like good for nothing... Use it or don’t use it... it does not matter much i think you should invest your time looking in to other important areas and i believe that will be the better use of the time!

I have personally used Hootesuite and Sprout Social also seems a promising tool to me!

If you are asking for normal Social Media management tool which does not required any advance feature then my idea is to take a trial version of both tools and see what fits your need and if both tools can get your work done, just check the prices and make the decision (No Rocket Science).

Links coming from PRWeb and other Press Release websites should be no-follow and Google is quite finicky about this and do not allow anyone to build links through this press release related sites.

Hope this helps!

At the moment you are in Google but not really following the Google guidelines as far as the thin content is concern... once you will apply the rule you will be more nearer to Google guidlines which simply means Google will love you more...so no big problems!

You might see a lil ups and downs in traffic but it will be ok within days of time!
