I understand that you started your online business fairly recently. I have run my own clothing brand for five years, and I have also learned from my mistakes. We needed to optimize the site’s speed, so we turned to Hey Reliable. You can check out their website at https://heyreliable.com/technical-seo/ . They also perform technical SEO audits. They did everything necessary: minimized the code, compressed the images (as it turned out, this greatly affects the loading speed of the site) and so on. We recently asked them to optimize the site for mobile devices, it’s important to always monitor your site so that new problems don’t arise, because you could lose a lot of customers because of them.
