      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!

            Can I replace categories with a static page

            Hello there. I want to replace all of WordPress categories with static pages so that users see a well designed and constructed presentation of all the articles within each topic instead of just a long list of excerpts. I've already done this with 2 categories and although it is hard work I can't help feeling it is a much better thing for my users. However, I'm concerned that I am embarking on this project without being totally sure that it makes sense from an Seo point of view, or whether there are any downsides I haven't thought of? My idea is that the  WordPress categories are set to noindex and nofollow. Search engines should find all of my static category pages and all of the content within each category will be spidered from there instead. Just to be sure you know what I mean here is a link to a normal category - https://www.whitegoodshelp.co.uk/category/consumer/ and here is my static page replacement for it - https://www.whitegoodshelp.co.uk/consumer-rights-appliances/ Both pages contain links to all articles within the category except the one generated by WordPress is just a long paginated list, and my replacement is a proper category page, which is hopefully far more useful . Can someone please confirm that there are no downsides to this strategy? 🙂

            Affect of ™ and ® in title for SEO

            I am looking at adding the trademark and rights reserved symbols to some of my titles. I think this might help with click through rate. From what I have found, this shouldn't have an affect on SEO unless it makes the title too long. Is this correct? Stephen

            Do Blog Tags affect SEO at all anymore?

            We're trying to standardize the use of tags on our site amongst writers/editors, and I'm trying to come up a list of tags they can choose from to tag posts with - and telling them to use no more than 10 (absolute maximum) per post. We are also in the process of migrating to a new CMS, and have 8 defined categories that will all have their own landing page within our "News" section. TLDR: Do blog tags have any impact on SEO anymore? Are they solely meant to help users find articles related on popular topics, or does creating a tag for a popular topic help to improve organic visibility? Full Question: With the tag standardization, I want to make sure we're creating the most useful and effective tags; and the UX/SEO sides of my brain are conflicted. To my understanding, creating a tag about a high volume topic in an industry helps establish the website's relevance to Google/other search engines about that topic and improves overall relevance; but the tag feed page (ex: http://freshome.com/tag/home-protection/) isn't really meant for organic search visibility. So my other question is, is it worth it to noindex the tag pages in the robots.txt? Will that affect any benefit to increased relevance for Google (if there is any)? I'm interested to hear others' thoughts and suggestions. Thanks in advance!

            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..

            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
