Frequently asked questions

There is no fixed page count. You pick a scope instead, and the same service covers everything from a one-page landing to a multi-page site or web app. Once we list the screens you actually need, the scope settles and you get a fixed quote rather than a range.

Yes. The domain stays, and where addresses change we set permanent redirects from the old URLs to the new ones so the accumulated search signals carry over. Skip that step and the existing search traffic disappears the day you switch.

If you have materials we use them. If you don't, we work out together what the site needs to say, though writing the copy and shooting the photos are not included in the quote. We can arrange those separately.

Yes, if we build an admin screen for it. That is an add-on and shows up in the quote. If little changes often, it is cheaper to skip it and handle edits through maintenance instead. We will tell you which fits once we know how often things change.

Not right away. It takes days to weeks for search engines to crawl and index a new site, and longer for rankings to settle. What we do is make the site indexable; we do not guarantee a position for any given query. If someone guarantees one, that is a reason to doubt them.
