As a blogger i visit many blogs daily and when ever i found an 
interesting blog i just subscribe to that blog via email for latest 
updates. But not all blogs i visit are in my good books. Some websites i
 visit will force me to leave the website as soon as possible. So what 
is going wrong with that website i mean definitely the webmaster of that
 website have put in a lot of efforts to make his or her site perform 
better but still there are some crucial things in every website which 
needs to be correct other wise you may lose precious visitor which may 
become customer in future.
1. Popups.
Some people think that its a cool idea to show some ads via popup 
when some one visits there blog but unfortunately 95% people hate 
popups. Its really a cheap idea to show ads to your visitor and not only
 it will hurt the image of your blog in the eyes of visitor but sear 
engines also don’t like popup and may penalize your blog. If you want to
 show the ads just put them in the sidebar or footer of your blog, don’t
 do silly thing like this.
2. Website Loading Time.
If your blog takes ages to load than people will not wait and move to
 another blog. I know internet speeds are grown over the years and now 
many people have access to the high speed internet but still you have to
 target the whole audience including the dial-up users as well. Some 
times slow speed can be because of your slow web-host servers so try to 
move your blog from slow to high speed web-host for better loading time.

3. No Fresh ideas.
I think if you are publishing same old ideas again and again this is 
the main reason why your blog visitors are not getting back. many 
bloggers reproduce same articles again with some new title to fool 
readers but now people are very knowledgeable and they can very easily 
and quickly guess which blog is producing original content and which is 
reproducing ideas from other blogs. So try to produce your own blend 
with some unique ideas and than see the magic.
4. Not replying to your blog Comments
Everyone in this world want to be appreciated by others and that why 
if you are not replying to your blog comments commentator will thought 
that you are not giving importance to him or her and next thing you can 
expect from them. Easily you can loose many visitors by such laziness. 
Manage some time for answering your blog comments every day and you will
 feel that visitors are coming back to your blog frequently.
5. Lots of Ads less Content.
I know everybody wants to earn as much money as they can but what if 
your blog visitor can only see ads specially above the fold. This will 
surly put negative impression in the minds of visitors and they might 
not read the article for which they come to your website.
6. Not updating your blog frequently.
Although its not necessary to update your blog daily but what if you 
post only 4 or 5 articles in whole month. This is not going to help you 
and your blog readers will rate your site as dead site and move on to 
another website. In my suggestion you should at least post 15 -30 
articles in one month so that your blog look more up to date.
7. Poor Blog Navigation.
If your blog has categories and archive than why are you hiding these
 pages. Its very important to present nice and easy navigation to your 
blog visitors so that they can easily find what they want. What if you 
have write an articles months ago than this article will surly be hidden
 some where in your blog pages. So one must show popular posts, most 
commented post and your most important post on the front page of your 
blog.
8. Funky theme colors.
What if you are using many colors in your blog theme and specially 
red color which is the represents only for danger. Yes you can use red 
color if you have a blog related to valentine or blood etc. Always try 
to make a combination of light colors like white with blue or green or 
any light color which you want. Also try to use less colors and one main
 color to represent your blog. Confuse which theme to choose here are

9. Rubbish Fonts and Size.
It doesn’t mean that if you like some thing than other are also like 
it. If you use rubbish fonts on your blog with size greater than 18px 
than its time for you to adjust your blog and use font which are more 
common and can easily be available on every one’s computer. Also avoid 
using too many flash files as these files require plugin to show up and 
if visitors has no flash plugin install than your blog will look 
horrible.
10. Sharing unrelated content on Facebook Fan page.
You Facebook fan page is the place where your blog readers can visit 
and remain update with your blog updates. If you post constantly 
unrelated content on you fan page than sooner or later people will start
 leaving your fan page and hence your blog too. Read article on how to customize your Facebook fan page.
