8 secret mistakes bloggers

• Launching before there is a fixed template.
  Most blogging tools in a variety of services such as on Blogger blogs offer a default template. Typically a beginner, they still persist in the template for some time. But if it is really serious about wanting to create a blog with loyal readers, then it is appropriate that you make your own templates. It is true, matters once the technical templates. But at least, try to find a unique template. Perform modifications, although only perfunctory.Importantly, these modifications are sufficient to distinguish your blog from other blogs.

• Unregularly posting.
  When you decide to make a blog, means you are committed to filling it periodically. It is true that the discipline is an attitude that is rather difficult to sustain. Whether because of time constraints, forgetfulness, or other reasons that may emerge. In fact, 500 words or 2-3 links of interest alone is enough poured in a posting. Maintain the blog as well as maintaining domestic animals or plants. It's OK, when you forget to feed him once in a while. But, if it kept you do, do not you know the consequences ?
• Excessive obsession on comments, trackbacks, and statistics.
  Do not assume that a post has not yet given no meaning if in-comment or trackbackfrom your blog / website other. In the early days of blogging, beginners often check thecomments every one-two hours. But that's just useless. As long as you have written a good, readable format, and a clear vision or goals, visitors will come by itself. Believe me, the obsession over the comment, trackback, or statistical, will only producedepression in yourself.
• Excessive obsession on the features
  Beginner bloggers tend to be obsessive on features that actually has not really necessary. Call it, JavaClock, Amazon wishlist, flickr, del.icio.us, podcasting, GoogleAdsense, and many more. Though better prioritize features that standard. SyndicationAtom / RSS / RDF may have become a primary need at this time. But more than that, visitors may find information that is unique and original. Legitimate you add various kinds of features in your blog. But first, make sure that they really need it, or at least,they are not bothered with it.
• Which is important and what is not important
  Many novice bloggers, especially teenagers, who posts trivial things like how many times they look in the mirror in one day, how much opposite sex that they gebet everyday, how they are so annoying teacher that day, and other things not at all essential . It is true that blogs are similar to online diaries. But please distinguish between thingsthat should be written in the blog and the things that is quite personal diary written in it.
• Copy-paste the resignation.
  Blankspost not only happen in the case of telecommunications alone. Sometimes the head of a blogger feels so empty, so there is absolutely no inspiration to write.However, if forced to do copy-paste, remember always to include the original source, do not traced it raw like that, and it be great if at least one or two sentences that containunique comment or response from you.
• Excessive ambition.
  Some bloggers beginner, sometimes hope to be soon achieved fame in the blogging world in an instant. Obviously it is something that is impossible. Even the author of a book / novel best-seller just simply write one or two paragraphs per day, then leave todo other activities, and finish it in stages at a later time. In the world of blogging, fameis not obtained within one day. If you want the fame, just do it with patience. Determine the target is realistic and reasonable. Do not be selfish. Do blogwalking and leavecomments on other blogs sufficient quality. Reply with either email or the comments that go to your blog.
• URL address remains.
  Perhaps this is less relevant today. But earlier times, it is very difficult (and expensive)to get a domain and hosting are quite reliable. The solution, free hosting facility be the answer. At first glance, from the cost side is indeed a practical solution that is cost effective. However, be aware that there's no free lunch. One by one facility that began to fall free. They began to limit the bandwidth, the facility, remove FTP access and CGI, and some others began to impose even higher costs. As a result, have oftenmutually URL address. You also often get annoyed when your friend is not oftenchange the number so when you need it, it is very difficult for you to contact him ?
