I want to know how to indicate a particular word or work is not spelt incorrectly. Spelling does affect SEO but the common spellcheckers usually come up with around 10-20 errors per page, but these words just aren't in the dictionary being used, most of these may not be in the dictionary google normal uses for
define phrases. Some are headings, others are just rare words but essential to the content.
How I can semantically (or in some other way) markup the fact that these words are correctly spelt? Will having tooltips over them help (several have tooltips to explain the words).
These problem words cannot be substitued for alternatives. Some words also are very similar to dictionary words but with the last 3-5 letters altered so they really do look to spellcheckers like they are wrong.
Both google and moz.com including spelling in ranking quality of pages.
Any possible solutions?
