      Can ID and class be used in my H1 tag. I realize best case would be to change it, but it's going to require a change order from the ecommerce company to fix their sloppy code. Will this hurt seo?

      Example:

        Absolutely agree with Dana here. Stylizing H1 elements is very common, both classes and ids can be used to achieve this.

          Hi Keith,

          This it totally fine. Using class within the

          is very common. The ID isn't a problem. Googlebot still understands that this is an

          . I think as time goes forward, some of these technical SEO elements will become less important. Search engines are going to understand, particularly as HTML5 becomes more widely adopted, that <h>tags are used as much to define stylistic elements as structural elements. Hope that helps!

            Tags vs. Categories? What should I use?

            I'm starting with a blog (self-hosted wordpress) and I'm thinking of the following content structure so that the readers are easily able to locate relevant content: Background: It's a blog which gives people relevant info about government jobs. To start with we will just be publishing information about these jobs but over a period of time also intend to post content that helps readers prepare for these jobs. In other words, right now it's just about detailed job notifications but in the coming months, we shall also post about preparation-related information. Typically, each of the job notifications can be bifurcated like: Jobs basis industry Banking Railways Clinical, etc. Jobs basis company ABC co. DEF co. XYZ co. etc. Jobs basis State / City City 1 City 2, etc. Jobs basis educational qualification Graduation Post-Graduation, etc. Now, I'm seriously confused how should I structure this data from the perspective of Categories & Tags such that it's reader as well as SEO-friendly. Do note that each of the government jobs post ideally falls in a couple of above mentioned categories. Thanks..

            ECommerce Filtering Affect on SEO

            I'm building an eCommerce website which has an advanced filter on the left hand side of the category pages. It allows users to tick boxes for colours, sizes, materials, and so on. When they've made their choices they submit (this will likely be an AJAX thing in a future release, but isn't at time of writing). The new filtered page has a new URL, which is made up of the IDs of the filter's they've ticked - it's a bit like /department/2/17-7-4/10/ My concern is that the filtered pages are, on the most part, going to be the same as the parent. Which may lead to duplicate content. My other concern is that these two URLs would lead to the exact same page (although the system would never generate the 'wrong' URL) /department/2/17-7-4/10/ /department/2/**10/**17-7-4/ But I can't think of a way of canonicalising that automatically. Tricky. So the meat of the question is this: should I worry about this causing issues with the SEO - or can I have trust in Google to work it out?

            Do you think using accordion text can hurt SEO?

            I have a lot of text for my home page. My plan is to a J Query Plugin for accordion text. Does anyone think that this can hurt SEO efforts?

            Missing meta descriptions on indexed pages, portfolio, tags, author and archive pages. I am using SEO all in one, any advice?

            I am having a few problems that I can't seem to work out.....I am fairly new to this and can't seem to work out the following: Any help would be greatly appreciated 🙂 1. I am missing alot of meta description tags. I have installed "All in One SEO" but there seems to be no options to add meta descriptions in portfolio posts. I have also written meta descriptions for 'tags' and whilst I can see them in WP they don't seem to be activated. 2. The blog has pages indexed by WP- called Part 2 (/page/2), Part 3 (/page/3) etc. How do I solve this issue of meta descriptions and indexed pages? 3. There is also a page for myself, the author, that has multiple indexes for all the blog posts I have written, and I can't edit these archives to add meta descriptions. This also applies to the month archives for the blog. 4. Also, SEOmoz tells me that I have too many links on my blog page (also indexed) and their consequent tags. This also applies to the author pages (myself ). How do I fix this? Thanks for your help 🙂 Regards Nadia

            H1 tag in the footer?

            Quick question: I have been scouring SEOMoz.org along with webmaster forums looking for an answer, but we have a person who insists that the H1 tag be located in the Footer. I feel that is is fundamentally wrong because it is not the intent of the H1 tag, and I do not believe it is a best practice. That being said would we see what little value the H1 tag has disappear if we put it in the footer, would we be penalized, or am I being too vanilla by wanting to keep it in the Title position?
