It is incredibly important to update your blog consistently. There are way too many people who get started blogging and let their blogs die a slow death. Some people simply do not update on a regular basis and the readers lose interest. Other people stop posting altogether! Keep it in your mind that you are running this blog as a real business. You need to have a regular schedule of posting so that your readers stay interested and your rankings stay strong in the search engines.
Note that the search engines love fresh content. They know that people are looking for the latest and greatest information. That means that if your blog is updated consistently, the search engine spiders will visit more often! This can help to improve your search engine rankings. Not only that, but you will also have more content out on the web just waiting to be ranked and found by people in your niche. The more content you have, the more keywords your blog will tend to show up for in the search engines. All of this can lead to improved rankings and more people finding you through the organic listings.
In addition to SEO, you should update your blog with fresh content for your readers. People love to visit blogs where they know they will always get new information from the bloggers they love best. It can be frustrating to visit a favorite blog, only to find that it has not been updated for quite some time. No matter how strongly your blog started off, the second you stop updating regularly you'll probably find that your readership and earnings drop off.
Unfortunately, it's not always easy to find time to blog every day. That's why many people choose to schedule blog posts for future release. You don't need a post for every single day, but you should attempt to have them at least a few times a way. That way, people will know when to expect the content and they know that it will always be there when they visit. There is nothing quite like knowing that you are fulfilling your reader's needs by always having something new and interesting for them to read!
You also need to stay up-to-date with the latest information related to your niche so you stay inspired to write these posts. Read industry magazines, visit other top blogs in your niche, read the news, take stock of the latest products, and so on. Doing this will always give you good ideas of things to blog about and it will help your readers -- your blog will be seen as highly relevant and up to date.
Take the importance of having fresh content into consideration -- the chances are good that your blog will be much more successful as a result with both your readers and search engines.
