I have been doing few reviews for few blogs and contests for the last 1 month, and from there, I get few ideas which I can use as a guideline when giving a review. Plus, doing some researches on internet has giving me clearer idea about it

Follow the rules
When you’re reviewing blog, you will need to follow the reviewed blog rules. Normally, the most common rules are anchor text, link back to the blog or post, minimum word and etc. In order to follow this, please plan your review before start writing to match their anchor text and the link URL

Content
The first place that I will look at is their RSS reader. I’ll subscribe to RSS feed and from there I’ll go through from 1 articles to another. I feel more comfortable reading from RSS reader since it will pull all articles into 1 page (your reader). But, not all blogger provide full feed. The problem with partial feed is, you have to go to their blog reading the full story before come back to RSS reader looking for another articles.

Few area that you can look at.

• Best content - highlight few best contents and recommend it to your readers
• Topic covered - 1 or multi topic
• Why you should or shouldn’t read this blog

Blog’s physical looks
This would be the second part that I will look at. Although is not as important as content, but it does play it own roles in attracting visitors especially new one.

There are few parts that you can review

• page loading time - How fast web page loaded
• Graphical user interface (blog’s template)
• plugin - eg: too many unnecessary plug-in, or missing crucial plug-in
• advertisement - eg: too many ads or too early the blog
• RSS - eg: Location, full or partial feed

Suggestion
If you’re think that there are few areas that might need some improvement, suggest it to them

Honest
Whenever you follow the above guides, do it honestly but does not means we critics the author personally. Being honest will credit you back later on.

After all, this is few guides that I will try to use when giving review in future. If you have better source or ideas, do not hesitate to leave your comment below
