Kyle Hawk: Quality, unique content. Make sure all of your HTML validates so Google can actually read the content. Make sure the pages are accessible (robots.txt / sitemap.xml). HTTPS never hurts.
Andy Terry: Been about that since i last done any web design to be fair lol.
Whats the best way for the website to rank within google.
Roma Alloui: Choose keywords you want to target, then look at your competition to see what keywords they are targeting, then run your own keyword research campaign, select the right keyword for a page and offer quality content based on users intent and not just to rank (you want customers and not window shoppers). Make sure you site is SEO and Mobile Friendly. Having a fast website will boost your user experience (UX), so optimize your graphics for speed and SEO. Like Kyle Hawk said, HTTPS will not hurt and it`s worth it. Plus many many more.
Steve Gerencser: None? Google (and most search engines) hasn`t used those as a ranking factor for 15 years or more? If you want to use them for completeness for some reason, just make sure that they actually apply to the content of the page.
