Is your website and blog ‘mobile’ friendly? This means, are they set up so that they can be viewed on mobile phones, tablets etc.
Google has decided that your websites and blog will be given a lower ranking if they do not comply to mobile requirements.
You therefore have to make a decision….is it important for your website to be found when being searched for by potential clients and do you want your website or blog to be looked at by folk using mobile phones etc.? It the answer is ‘yes’ to either of these, then you need to get your existing sites changed over.
