You can treat migration wordpress as a checkbox, or as a design decision. The first path is fast and ineffective; the second takes an hour of thought and lasts for years.
What the engine actually sees
Before optimising anything, look at the page as the crawler receives it, not as the browser displays it. The gap between the two often explains months of unexplained stagnation.
Simply comparing the rendered source with the initial source reveals in minutes whether essential content depends on execution the engine does not guarantee.
What it changes for the reader
It is tempting to treat this as a purely technical constraint. In practice, each of these optimisations translates into a clearer, faster or more predictable experience for the person reading.
That is precisely why engines care about these criteria: they approximate, imperfectly, genuine user satisfaction.
The role of HTTP headers
Status codes, cache headers, canonicals sent as headers: a significant share of technical signals lives not in the HTML but in the server response.
It is also where errors stay unnoticed longest, since they have no visible effect on screen.
Verify after every deployment
A correct configuration does not stay correct. A deployment, a hosting change or one new extension is enough to reintroduce a problem solved six months earlier.
An automated check at deploy time takes minutes to set up and prevents weeks of lost visibility.
Check before moving on
- Automate every repetitive check
- Document the decision, not just the action
- Schedule a review in six months
- Assign each point to a named person
- Measure before, not after
- Handle what affects the most pages first
Prioritise before fixing
An audit always produces more recommendations than it is reasonable to act on. Sorting happens on two axes: how many pages are affected, and how deep the problem sits in the chain.
An error blocking crawling comes before an improvable tag. Fixing the order costs more than fixing the content.

Key takeaways
None of these measures produces a spectacular effect on its own. It is their accumulation, sustained over months, that durably moves rankings. Start with whichever point is closest to your current situation, measure, then move on.
