<sub>& <sup>tags, any SEO issues?</sup></sub>
-
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 <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub>
Thanks.

Hi Jenny
jStrong is correct. Subscript (<sub>) and superscript (<sup>) tags are not going to have any effect (positive or negative) on SEO.</sup></sub>

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. __

# Tag - opacity and SEO impact
Hello,
Technical SEO | | Tiffany_Barn
I have a query animation 'fade-in-up' on my website: tiffanybarnard.com which moves the H1 tag slightly and fades it in from zero opacity to 1. Will this affect the SEO value of the H1 tag?
Thank you!0 -
Does having a sub-domain on a different server affect SEO?
I'm working with a company that has a hard-coded website on the root domain, and then a WordPress blog on a subdomain on a separate server. We're planning on implementing a hub and spoke model for their content, hosting the main hubs on the root domain and the linked articles on the blog. Is having the blog on a different server going to hinder our SEO efforts?

Setting title tag with javascript/jquery
Hi there, I'm looking for some advice. I've recently implemented a few jQuery functions which gets specific content from the page and then sets the title and description. See working example here. It seems to work fine but my question I have is whether Google bots can read it and whether it might actually hinder my SEO efforts? Any advice would be really appreciated! Peter

Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

Multilingual Website - Sub-domain VS Sub-directory
Hi Folks - Need your advice on the pros and cons of going with a sub-domain vs a sub-directory approach for a multi lingual website. The best would be a ccTLD but that is not possible now, so I would be more interested in knowing your take on these 2 options. Though, I have gone through http://www.stateofsearch.com/international-multilingual-sites-criteria-to-establish-seo-friendly-structure/ and this somewhat vouches for a sub-directory, but what would you say'?

How does Google find /feed/ at the end of all pages on my site?
Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?
