      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? 🙂

            SEO audit on a beta site

            HI there, Is there much point conducting an SEO site audit on a site that has not yet launched and is protected behind a login? Presumably none of the usual SEO tools (Moz, Screaming Frog etc) can crawl this site becuase it is all locked behind a login. Would it be better to launch it and then do a site audit? Thanks

            Less Tags better for SEO?

            I am currently reviewing my strategy when it comes to categories and tags on my site.  Having been no-indexed for some time, and having many tags with just one entry I am thinking that this is not optimal for SEO purposes. This is what I am planning: Categories - Change these to Index, but only after adding a hundred words or so by way of introduction (see this example - https://www.besthostnews.com/news/hosting/a-small-orange-news/).  With the categories I am thinking of highlighting key articles as well to improve link juice distribution to older articles that are important. Tags - About half my tags have only 1 entry, with a few more just having 2 entries.  I am thinking of deleting all tags with just one entry, and trying to merge those with just two or 3 entries where it makes sense to do so.  I will keep these as no-index, but I think this will mean more optimal distribution of link juice within the site. I would appreciate your thoughts \ suggestions on the best practices here.

            Does Bolding Text Have Any Impact on SEO?

            Someone told me it does but I thought that was old school way of thinking.  Any thoughts?

            SEO for Japan

            Google and Yahoo are the two major search engines in Japan. You can search using Western characters, and you often see English language results with Japanese (Chinese) characters next to them. As I don't speak Japanese, how do I approach SEO for my Japanese-language site? would appreciate any experiences and educational sources on the topic.
