This is a common question, and keeping things current really depends on what type of site you have. As SME sites tend to be static (in terms of information), the question about "fresh content" is pertinent. Recently, Google Webmaster Matt Cutts, speaking in India to an SEO forum, confirmed that Google does not use freshness of content as its sole ranking measure, and many sites do not require freshness at all. SBWD's developer Chris discusses below:
In a nutshell, Google looks what people search for, and ranks the results accordingly based on a variety of factors. There are three main types of searches people do,informational (looking for product/service information), transactional (looking to buy online and/or contact a service provider etc), and beyond that, fresh seeking searches(i.e. news reports on rubgy matches or world events). Not every search query needs freshness, so it is irrelevant to be fresh for searches that do not require freshness. Chatting with Matt Cutts, SME sites do not require you to be vigilant or focus creating on fresh content. Google uses over 200 signals for search engine ranking, with "freshness" being one; randomly changing words or inserting lower value content is not helpful for your ranking and popularity.
Where this leaves your site?
1. There is no need to look or be "fresh" to stay relevant. The searches for small businesses are informational and/or transactional - your SBWD-designed site ensures all the relevant information is presented and what a user would expect to see on your site is easily located.
2. The web pages our team designed are as good today as they were yesterday and will be tomorrow!
3. SBWD's team writes high impact content, which is designed to be found fast as well as being engaging for the reader. We only emphasis that your contact details should always be up to date and any new services/products included too.
