Welcome to the Q&A Forum

I am working on a team (my part is the SEO) where the developer added the .html extension to the permalinks. I don't understand why, on Wordpress, you would do this. Is there any benefit, or penalty for it as an SEO standpoint? I usually just set mine up %postname% as the permalink structure, but I am not the web design lead on this project. I asked the designer why, but he seems to be reluctant to answer any of my emails about his work, (like he is above that or something). Not wanting to make things worse, I dropped it and thought I would ask here since I saw a few posts in reference to it today in the forum. Is there an advantage or disadvantage (either way) to using the .html extension on a Wordpress site?

Seeing a recent comment about promoting infographs here in the forum, I thought I might ask if anyone has any resources on getting them made, obviously they are a great way to promote and are extremely shareable becoming a link building source. I am not a graphic artist so am wondering if any of you have used someone to build them with any luck?

My client has 2 WP folders (one is the main site, and one was for an added blog, don't ask me why they did it that way). They sent me the login for Google Analytics, and the first thing I see is 2 profiles, one for the main site, and one for the blog. Doesn't the code in the head of the main page cover ALL the subdirectories too? I could see this if it were a subdomain, but not in a subdirectory. Thanks in advance.

Should you ask your dealers for links back to you? For example, if you are a laminate flooring manufacturer, should you ask all your retailers to link to you? If so, how do you go about it? Emails? A form letter? Should I create a page on the site for banners and let them grab the code? Any creative ideas would help.
