The lead should adequately summarize the content of the article. (GA criteria)
There should not be anything in the lead not mentioned in the rest of the article. (GA criteria)
Wikilinks should only be made if they are relevant to the context. Common words do not need wikilinking.
A word only needs to be wikilinked once within each section.
Links within quotations should be avoided.
Logical quotation should be used, i.e. final punctuation belongs outside the quote marks, unless the punctuation is part of the quote and the quote is not a sentence fragment.
Only full dates or dates with a day and a month should be linked. The same applies to dates in the footnotes.
External links only belong in the External links section.
It is recommended not to specify the size of images. The sizes should be what readers have specified in their user preferences.
Text should not be sandwiched between two adjacent images. (GA criteria)
Left-aligned images should not be placed at the start of subsections.
All fair-use images need a fair use rationale. (GA criteria)
Images need succinct captions. (GA criteria)
An image caption should only end with a full-stop if it forms a complete sentence. (GA criteria)

Book references need the author, publishing date and page number. (GA criteria)
Book references preferably should include the publisher, city of publication and ISBN.
Web references need the author, publisher, publishing date and access date. (GA criteria)
Web references preferably should include the language (if not English) and format (if not HTTP).
References should be consistently formatted, eg. consistent author format, abbreviations for "page number", etc.
Blogs and personal websites are not reliable sources, unless written by the subject of the article or by an expert on the subject. (GA criteria)
Dead web references should not be removed, unless replaced.
Inline citations belong immediately after punctuation marks. (GA criteria)
Portal links belong in the "See also" section. (GA criteria)
"Further info" links belong at the top of sections. (GA criteria)
Lists should only be included if they can't be made into prose or their own article. (GA criteria)
Lists within prose should be avoided. (GA criteria)
Rather than hyphens, en dashes should be used for ranges, eg. 5–10 years, and unspaced em dashes or spaced en dashes should be used for punctuation, eg. The building—now disused—was built in 1820.
Page ranges in the footnotes, and sports scores should use en dashes.
" " (non-breaking space) should be typed between numbers and units, and other numerical/non-numerical components, e.g., "10 miles", "Boeing 747"
Imperial measurements should be accompanied by the metric equivalent in brackets, and vice versa. If possible, use a convertion template, eg. {{convert|5|mi|km|0}}.
Whole numbers under 10 should be spelled out as words, except when in lists, tables or infoboxes.
Sentences should not start with a numeral. The sentence should be recast or the number should be spelled out.
Only the first word in a section heading needs a capital letter (except in proper nouns).
Short sections and paragraphs are discouraged. (GA criteria)
Ampersands should not be used (except when in a name, eg., Marks & Spencer)
"Last few years" has ambiguous meaning; "past few years" is preferable in some contexts.
"Within" has a different meaning to "in". "Within" should only be used when emphasing that something is inside something, eg. "the town is in the county", "the town is within the county boundaries"
Periods and spaces are needed after initials in people's names, e.g., P. G. Wodehouse
Compound adjectives need hyphens.
A hyphen shouldn't be placed after an -ly word if it is an adverb, e,g., widely used word; except if the -ly word could be mistaken for an adjective, e.g., friendly-looking man.
"Century" doesn't need a capital, e.g., "15th century" rather than "15th Century"
"While" should only be used when emphasising that two events occur at the same time, or when emphasising contrast. It shouldn't be used as an additive link.
Using "with" as an additive link leads to wordy and awkward prose, e.g. "the town has ten councillors, with one being the district mayor" → "the town has ten councillors; one is the district mayor"
Beginning a sentence with "there", when "there" doesn't stand for anything, leads to wordy prose, e.g. There are ten houses in the village → The village has ten houses. The same applies to "it".
The words "current", "recent" & "to date" should be avoided as they become outdated. (GA criteria)
Avoid using "not" unnecessarily, eg. "songs previously not heard" → "songs previously unheard"
Avoid contractions, such as "can’t", "he's" or "they're".
Avoid weasel words, such as "it is believed that", "is widely regarded as", "some have claimed". (GA criteria)

Avoid informal words, such as "pub", "though", "tremendous" and "bigger".
Avoid vague words, such as "various", "many", "several", "long", "a number of", "just", "very" and "almost".

Avoid phrases with redundant words, such as "is located in", "the two are both", "they brought along", "they have plans to", "they were all part of", "the last ones to form", "both the towns", "outside of the town", "all of the towns", "received some donations", "still exists today", "it also includes others", "many different towns", "near to the town", "available records show", "to help limit the chance", "christian church", "in order to", "first began", "joined together", "future plans" and "in the year 2007".
