_{& ^{tags, any SEO issues?}}

[Jenny1]

Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a _{on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO₂.}

Thanks.

Hi Jenny

jStrong is correct. Subscript (_{) and superscript (^{) tags are not going to have any effect (positive or negative) on SEO.}}

Hi Jenny,

I don't think these tags would have any affect on the SEO. They are formatting tags the same as _or _that only affect the styling of the text they surround and it is unlikely that when crawled they are treated as anything but that. __
