SEO Technical Checklist: Crawl, Render, Speed, Logs

Most SEO technical problems show up as crawl and rendering issues rather than keyword choices. When rankings stall, the cause is often page speed, link structure or how content is rendered. This checklist helps marketing and engineering agree on ownership.

1. Crawl and Index

Start with coverage: how many pages are indexed versus how many exist. A large gap points to link structure or crawl budget, not content quality.

Then check entry points: important pages should sit within three clicks of the home page. Pages reachable only through site search are crawled less often.

2. Rendering

Rendering matters most. Crawlers execute scripts but with limited budget, so script-rendered body text may be captured incompletely. Server-render the main copy.

3. Structured Data and Snippets

Structured data decides whether a page can earn richer presentation such as FAQs, breadcrumbs and organisation details. Two rules: markup must match visible content, and never mark up content the page does not show.

Titles and descriptions belong to the same layer. Keep titles under about thirty characters in Chinese and descriptions within the recommended range; duplicated or empty descriptions get rewritten by the engine.

4. Site Structure

Three practices hold up: every section has a stable list page and URL; tag pages are only linked when they hold enough content; in-body links point to related sections instead of piling up in a footer block.

Tag pages deserve attention. A tag page with one item is a thin page that drags on overall quality assessment.

5. Logs and Iteration

Without logs, technical work is guesswork. Sample the access log weekly: crawl frequency, status code distribution, which directories get crawled. The ratio of 404 to 301 often reveals structural problems directly.

Start with a monthly check of crawl, render and speed rather than a one-off rebuild. When evaluating an agency, ask for this sheet; teams that can produce it are doing engineering work.

6. FAQ

How long until technical changes show?

Structural fixes surface in crawl and indexing within two to eight weeks. Rankings move more slowly.

Do we need a separate mobile site?

Responsive design covers most cases. A separate mobile site creates two URL sets and duplicate content.

Indexed but not ranking — why?

Usually intent mismatch or too many similar pages competing. Consolidate duplicates first.

Does SEO conflict with paid media?

No. They compete for different placements. Paid stops when spend stops; organic accumulates.
