Proofreading is a very important part of the writing process as it involves English experts to check the document so that the grammar, punctuation, and spelling and vocabulary errors can be identified and rectified. Good writing always involves modification and revision, and proofreading is the fundamental part of the process. Proofreading is the final quality check performing with the intention of detecting and eliminating errors such as typographical and grammatical inaccuracies. English proofreading has a process through which it is done strategically. 

Before starting the process, the revision of the larger aspects of the texts is a must. Corrections should not be made at the sentence and word level if still one needs to work on the focus, organisation, and development of the whole paper of the sections, or of paragraphs. Set the text aside for a while (15 minutes, a day, a week) between writing and proofing. Some distance from the text will help to see mistakes more easily. The unnecessary words are to be eliminated before looking for mistakes. From the comments of the professors or a writing centre instructor on past papers, make a list of mistakes need to watch for. Soon after these necessary steps, the process of proofreading starts. It will be more convenient to work from a print out rather than computer screen. Reading out the document loud, this especially helps spotting run-on sentences. More problems can also be heard if not read silently. 
Proofread for one error at a time, because if one attempts to identify and correct all errors at one sitting there is a risk of losing focus. Reading each word slowly forces one to voice every single word and involves the auditory senses in the process. Breaking the texts into manageable chunks provides with more manageable tasks. One of the most effective methods is the circling punctuation marks for spotting punctuation mistakes. 
The proofreading method is helpful for identification of the spelling mistakes as it forces to concentrate on each and every word on isolation.  Many proofreaders recommend reading sentence by sentence, paper backwards. On a regular basis, proofreading writing helps in the identification of own strengths and weaknesses. Using the search function of the computer to find mistakes likely to make is preferable. If one tends to make many mistakes, check separately for each kind of error, moving from the least to the most important. Ends with a spelling check by using a computer spelling checker or reading backwards word by word. Proofreading services provides a piece of work that’s grammatically correct, accurate and makes sense. 
Proofreading is the very last step in the writing process. However, just because it comes last, doesn’t mean that it is the least important. Proofreading ensures that the document is completely free of errors and polished to a high standard. Professional proofreaders take the roles they have pretty seriously and many of them will be completing various ‘’passes’’ through a paper so as to ensure that all the typographical errors, spelling mistakes, incorrect punctuation, and inaccurate words are found and corrected.
