Whether you are new to social media or have been in the game for a long time now, you should always be redefining your social bookmark submitting strategy. The world of the Internet moves very fast, of course, if you stick to the same technique for a year or more, you'll probably be making some mistakes.
Just what exactly should you be changing in your strategy? For starters, it's always a good idea to investigate new and old social bookmarking sites in order to know where your niche is moving to. Several just four or five users that start using a site and are interested in your market can really shift the center of focus to a new site, and you have to be on your toes to discover if this has happened. It's normal to fret that this might take a lot of time, but there are options to going into the sites and spending too much time there every day. Get Google Alerts for many keywords related to your small business, and as soon while you notice movement online that aren't your usual stomping grounds, investigate them.
Something I remind my clients of is that social bookmarking is not a a proven way street. If you approach it with just one objective in mind, you will likely be losing a fantastic chance to boost your business spending little more time a day on a bookmarking site or two. Ignore only using these sorts of sites to spam with the content and hope to get some extra traffic. This could give you a small boost in the short run, but in the long run your reputation will be ruined and you will generally find yourself banned from your most relevant sites. With all the proper social bookmarking strategy, you won't miss out on the great things these websites have to offer.
Whatever the site you might be using at the moment, always stay active, commenting on other people's links, placing useful links along with other websites and engaging in a conversation with the community. The one thing you have to take into account is that people are looking for information, not for publicity. So if you include phrases like 'buy my product' and even 'check out my site for nice discounts on...' you may automatically alienate 95% of the potential users. You will get a small boost in traffic, but again, this is a strategy for short term, not the long term. If, however, you place informative content and share your wisdom, you will probably not see immediate results, but little by little other users will trust you and have you as a referent inside your field, and that means good and regular business from loyal customers.
