Welcome to the Q&A Forum

Excuse the basic question. I host my domain and website on Squarespace. I use a specific theme and after doing a site crawl of my site Moz picked up that Pages and Blog posts 'Missing or Invalid H1' tags (450 issues!). I discovered that my Squarespace theme only using H2 tags. Is this a serious issue that affects my search visibility? What would you recommend that I do to fix this, if anything? I'm starting some SEO and lnikbuilding, but wanted to see if this is an issue that I need to consider. Thanks!!!!

Help: I have a website with a country-specific TLD. Google Console sees the target country as the same for the TLD, but tells me that I can  'select Unlisted' if I "want to ensure that your site is not associated with any country or region." The question is, how? I cannot see how to edit the country in the new console? Any ideas/help?

Excuse for the novice questions, but looking for help! 🙂 I have an established .co.uk website/blog for which I have established a good solid following in the UK over a good number of years. That said I have recently relocated to Dubai and so I am looking to target my English blog content to English speakers here and Singapore? While the language setting of my site is "en" is there anyway that I can change this to "en-ae" and "en-sg" for example to build a following in these markets? Or is my .co.uk TLD an issue that is going to hold me back from building following in these locations? I ask as I have just read the hreflang announcement from Google, but noticed in my Webmaster Tools that I get the following message: "Your site has no hreflang tags". Thanks in advance!

I am an SEO newbie, but learning fast. 🙂 I am based in London, UK and have a website: www.twofourseven.co.uk.  I noticed that the language attribute was set to 'en-US'.  I work in London as well in international locations in the Middle East and Asia. Thinking of this I wanted to ask the experts if given that I am based in the UK, would changing the language attribute make a difference to search results?  If so, would 'en' be better than 'en-GB', which might be too specific? Thanks in advance!
