Name the number that looks wrong
Marketers usually spot a symptom in a report: low conversion, a high bounce on mobile, double-counted visits or fewer leads than clicks. Each points at a different cause. Heavy pages show up as slow loading on phones. A duplicate tag shows up as inflated page views. A form that does not deliver shows up as a gap between submissions in the builder and leads in the inbox.
Write down the page address, the number, the report it comes from and the date it changed.
- Slow on mobile: weight and scripts.
- Doubled views or mismatched conversions: tags.
- Fewer leads than clicks: form delivery.
Separate the three causes
Page weight is mostly images, fonts, video and third-party scripts, and a builder lets you change only what is on the page. A tag problem is usually two routes for one tag, such as the builder's integration and a pasted copy. A form problem is a stage failing between the page, storage and the mailbox. They can all be present on one page, so each gets its own check rather than a single score.
No one can promise a ranking or a conversion lift from any of these. What can be shown is measured weight, a count of tag requests and a delivered test submission.
- Measure weight, tag requests and form delivery separately.
- Change one cause at a time.
- Record the date of each change next to your reports.
One-off or every month
A one-off job fixes one page once. Campaign pages change often, though, so the weight and tags tend to drift back. A monthly weight and speed check covers up to three named pages against an agreed budget, and a monthly forms and embeds check covers up to three forms and three tags. Both are standing services with a written monthly summary and can be ended at the end of any month.
- One page, one problem: the one-off job.
- Pages that change every campaign: the monthly service.
- Both can start from a written scope, with no access asked first.
Starting the conversation
Send the page address, the builder and the symptom. Prices are untested proposals, for example £345 to bring one page within an agreed weight and speed budget and £125 to fix one tag or widget, and payment follows the agreed checks and your sign-off. This is a new service with no client history to point to, and the first enquiry never needs logins or customer data.
