Special Characters in Title Tags & Meta Descriptions
- 
					
					
					
					
 Do special characters, such as the "&" symbol or a "," in title tags and meta descriptions negatively affect your ranking in search engines? Any feedback is much appreciated. Thank you!

 They will not negatively effect your SEO. In general the pipe character " | " is used to separate title segments. Further situations make sense as well like "&" is used to shorten "and" since "and" is generally of no value. Thus, "&" saves you 2 characters. For example the title of this page is: Special Characters in Title Tags & Meta Descriptions | Moz Q&A Hope this helps, Don

 The general thought is that they will take up valuable ranking landscape, since your title lengths are limited to begin with.

		Finding websites that don't have meta descriptions
 Hi everyone, as a way to find new business leads I thought about targeting websites that have poor meta descriptions or where they are simply missing. A quick look at SERPs shows this is still a major issue for many businesses. Is there any way I can quickly find pages for which meta description is lacking? Thank you!

		<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. Technical SEO | | Jenny10

		Page titles in browser not matching WP page title
 I have an issue with a few page titles not matching the title I have In WordPress. I have 2 pages, blog & creative gallery, that show the homepage title, which is causing duplicate title errors. This has been going on for 5 weeks, so its not an a crawl issue. Any ideas what could cause this? To clarify, I have the page title set in WP, and I checked "Disable PSP title format on this page/post:"...but this page is still showing the homepage title. Is there an additional title setting for a page in WP? Technical SEO | | Branden_S0

 This seems silly, but I have errors on blog URLs in our WordPress site that I don't know how to access because they are not in our Dashboard. We are using All in One SEO.

		Iframes & SEO
 I've got a client that wants a site with all content in iFrames. They saw another site they liked & asked if we could do it. Of course we can technically. How big a negative hit would they take with SEO? Is there anything we can do to mitigate it, such as redirects, etc? Thanks for the help!
