As I suspected, Your NAP (NAME ADDRESS PHONE) lacks consistency which in turn will display incorrect information and can actually work negatively towards your national and local rankings on Google.
Over the last few years Google has adapted its algorithm to return more favourable results for local and national customers across the country. Google's new algorithm is an extension and looks for external sources to establish NAP and reputation through reviews.
To ensure that your rankings are achieving full potential your going to have to fix your citations, telling people your business is here, and then on other websites a completely different address will lose you brownie points with Google.
Your going to have to pay someone or spend a lot of time amending 'EXTERNAL' sources with correct and current data. You should also use this opportunity to add value to those citations with unique text and pictures, this will make the pages more valuable, and may increase leads.
Good practice when correcting or making citations is:
- Ensure that you use your full company name, i.e bits and bobs LTD, not bits & bobs. Use whatever name is used on gov uk, and company check.
- Ensure that you use an addressed registered with royal mail, do not add department names to added as these are internal addresses and likely confuse Google.
- Use one telephone number if possible.
- MOST IMPORTANT make sure every citation is exactly the same as the others in regards of NAP.
You should first start by amending your Google Plus page, as this is the most important factor.
You should then start to fix others, this is only an example as time is money and I don't have the time to list every site your business is mentioned on,
You should also amend problems with the NAPW (Name Address Phone Website), some citations are pointing to .co.uk and some the .com (choose one, and stick with it).
