Storefronts that stay fast when the traffic arrives

Only if you have a reason. Headless buys you front-end freedom and a higher speed ceiling, and costs you platform features you now maintain yourself. If your theme is the bottleneck and your team is small, fixing the theme is usually the better trade. We will tell you which situation you are actually in.

Not automatically. Magento is heavy but capable, and a lot of "Magento is slow" turns out to be extensions, uncached blocks and an unindexed catalogue. We have worked on it for years, so we can tell you whether you have a platform problem or a configuration problem before you spend a migration budget.

It can, badly, which is why it is the first risk we plan around: URL mapping, redirects, structured data, and a crawl comparison before and after. Rankings usually wobble for a few weeks even when everything is done correctly. Anyone promising otherwise is guessing.

Load testing against your own historical peak, a caching and queueing strategy for whatever fails first, autoscaling with headroom, and a code freeze window agreed in advance. Then someone on call who knows the system rather than a generic support line.

Three places reliably today: search relevance, product content at catalogue scale with a review step before publishing, and support deflection on order and returns questions. Personalisation helps once you have enough behaviour data to learn from. We would rather fix your search than sell you a recommendation engine you cannot yet feed.
