      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

          . 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!

            Homepage SEO optimization

            Hello, I’m almost ready to lunch my new website https://thetravelhoop.com , I just need to create the content of the product page and put all the images. I would like to know what you think in terms of SEO of the home page (is the content that I want to rank the most). My doubt is that since it is a landing page, there is not a lot of text but mostly <h>. It’s not a styling decision of course (I know is bad practice) but mostly because they are supposed to be title/headings.</h> Do you think I’m doing something wrong, or do you have any suggestions? Thank you, Daniele

            SEO Implications of using Images for Article Titles

            Hi guys! New to Moz Pro. I just recently completed an online course with Moz... I have a client who is writing some new content for their site, and we are approaching it with SEO in mind. I was wondering about using an image with text on it as the article title, instead of an actual "text on the page" title. Wondering if that's going to "cost" us anything, SEO wise. I guess we could use alt-text/title/description fields to make sure the keywords are crawlable for our article title but do they have less "weight" than a standard title? How does that work? Hope my question makes sense. Article header attached mB0PXsA.jpg

            Tags - Good or bad for SEO

            We are getting Moz errors for duplicate content because tag pages share the same blog posts. Is there any way to fix this? Are these errors bad for SEO, or can I simply disregard these and ignore them? We are also getting Moz errors for missing descriptions on tag pages. I am unsure how to fix these errors, as we do not actually have pages for these on our WordPress site where we are able to put in a description. I have heard that having tags can be good for SEO? (We don't mind having several links that show up when searching for us on google...) As far as the SEO goes, I am not sure what to do. Does anyone know the best strategy?

            SEO Optimization for Sales Page

            Hi, I am new to eCommerce. Traditionally I have run a couple of semi-successful websites relying largely on Adsense revenue and affiliate income. So I have a bit of experience with on page and off page SEO. This time around I am creating a membership site and also sell eBooks as bundles that non members can buy. My question is, should I SEO optimize the sales page for my eBook or use another content page that links to the sales page. For example, if I am selling an ebook on Dog Training and targeting the main KW "Dog Training Tips", should my sales page be optimized for "Dog Training Tips"? The reason I ask is because typically Sales pages do not provide a lot of useful information but are more geared around selling the product. The other option would be to create a helpful information page targeted for "Dog Training Tips" and lead users to my sales page through contextual links, banners, popups (I hate popups), etc. This would be the approach for the other LSI keywords anyways. Any thought would be appreciated.

            SEO for Online Auto Parts Store

            I'm currently doing an audit for an online auto parts store and am having a hard time wrapping my head around their duplicate content issue. The current set up is this: The catalogue starts with the user selecting their year of vehicle They then choose their brand (so each of the year pages have listed every single brand of car, creating duplicate content) They then choose their model of car and then the engine And then this takes them to a page listing every type/category of product they sell (so each and every model type/engine size has the exact same content!) This is amounting to literally thousands of pages being seen as duplicates It's a giant mess. Is using rel=canonical the best thing to do? I'm having a hard time seeing a logical way of structuring the site to avoid this issue. Anyone have any ideas?

            Can I use Same Keyword for Multi pages Title Tags?

            Hello All, I am working on client website and currently they are targeting One Keywords for multi pages. As I have search with Allintitle: Search query and Google display around 37 pages of website which carry same keyword in "Title Tags". I have told to client to change the "Title Tags" but they want that keyword for all relevant pages. So I want to know is that harm in Search Engine Ranking? Note: They have not done the link building activities for multi pages with same Keyword, they are using only in "Title Tags" only
