With Google you want to virify your site with the Google Webmaster Tools. There you can submit a sitemap.
Bing have a similar Webmaster Tools to do the same thing.
Then check all the data they report for issues or oportuinities.
The key starting point to SEO is content. If you provide original textual information about what you offer, no other work will convince search engines to send people to you, when they are looking for those things.
Your products seem to have good descriptions, but your home page and collections are void of original text.
Your're very image based, so make sure you set up alt attributes with good summaries of the images.
And check out the SEO section for products and collections. Make title tags and meta descriptions that will make people want to click.
Thank you.. I went through the tedious work of renaming and including alt text for each product image the past few days. I will do more work with meta descriptions for each product, home and collection page also.
Is it okay to have a some product pages with similar meta descriptions, words which are basically few lines of product description copy/pasted? Many of my products are similar with slight variations in material only so some of my descriptions are the same.
It's fine to have duplicate meta descriptions, especially if the same description makes sense for multiple pages.
You may see duplicate warnings in the search console about it. But they are just basic warnings to try and detect if you have true duplication issues.
Ideally you want the actual page descriptions to vary. Otherwise the pages are in direct competition with each other. It can be better to combine varaitions and options into the one product page instead of creating many near duplicates. So instead of competing, they are combining forces.
