8) Make sure names are spelled correctly

The single most important mistake is misspelling of names. Going to whatever length needed to see that names and titles are correct is important.

9) Look content from readers point of view:

Read story completely through first time, without marking or changing anything. Thats way reader is going to read story, and thats way copy editor should read it, too.

10) Look for answers:

When editing a story for first time, looking for answers to following questions is important:- Is this a complete story? Does it consist of important facts? Does it give all of necessary information to reader? Are quotes interesting? Any information or necessary quotations are missing? Does writer omit information on assumption that reader already knows it? Does story read smoothly? Does information flow from one paragraph to next? Do quotes add to and support previous information? Are facts and quotes in descending order of importance?

11) Make sure text is optimized for search engine rankings:

Check whether META tags (for description and keywords), Title tag and Image Alt tag have been used appropriately for website content. Your text should also contain main and related keywords/ phrases for your site. This will make audience find your site on Internet.

The basic processes, are much same for online documents and print media - checking for correctness (spelling, grammar, and punctuation), consistency of capitalization and other mechanics, accuracy of information, and completeness. Creating consistent text formatting, Checking consistency in visual design, Testing for proper working of website links, Knowledge of HTML and its application (when required) are additional responsibilities for an online editor.

Secondly, does person giving advice have an underlying motivation - or is it 'independent'? If they are recommending use of a particular widget on your web site, and they are actually selling that widget, even as an affiliate, how useful is that advice? This is where you need to look for supplementary advice from third parties, such as via testimonials.

Thirdly, ensure that it works for you. Something may have worked for someone for a whole myriad of reasons, such as time, place, coincidence, a particular type of business, a particular type of visitor, and so on; but, that doesn't mean it will work for you.

For example, use of banner graphics has completely different results on different web sites. On some sites, they improve sales. On other sites, it's been found that sales can be increased by removing banner. The same can be said for use of guarantees. In brief, something that works well on one web site may have opposite effect on another.

You always need to test it out for yourself, and make up your own mind based on your own results, before coming to a conclusion on whether a particular piece of advice helps you towards your own goals.
