Should you correct the grammar of the comments on your blog as Google may penalize a page for poor grammar and spelling? Matt Cutts said nothing to worry.
SEO folks: we recently launched a refresh of this algorithm: goo.gl/3yk0Xo Visible to outside world on ~Feb. 6th.
The question was – ‘Should I correct the grammar on comments to my WordPress blog? Should I not approve comments with poor grammar? Will approving comments with grammar issues affect my page's quality ratings?’
Matt explicitly stated that one need not worry about the grammar in comments and just needs to make sure that the grammar on the own page is fine. There are people around who will just write anything, not making any sense. YouTube videos and several other properties may have all sorts of comments, which doesn’t mean they won’t rank.
However, Matt advised people to watch out for spam comments. You can make out the difference between a comment left by a spam bot and a real person. If the comment has been left by a real person, but the grammar is not perfect, it is fine to accept the comment as it is.
Matt pointed out that bad grammar in a comment reflected more about the writer and not the site, so one need not stress about it.
This means less work for the SEO’s, who would have spent a lot of time correct the time otherwise!Matt Cutts Says No Need to Correct the Grammar of Blog Comments!,
