Define the role of the page
For the service, choose materials that reveal the typical questions of the client. For the article, there is one main service, several related explanations and a relevant case study. Do not attribute results to a case that it does not support. Put the link to the price where the reader already understands the scope of work and wants to estimate the budget.

Make the anchor meaningful
The link text should describe the purpose: "check for repeated API requests" is clearer than "here". Use plain HTML links with an accessible address. For language versions, direct the reader to the appropriate language and canonical URL, without unnecessary redirects.

Check the route in two directions
The new article should receive links from the blog and the relevant page, and not just exist in the sitemap. After changes, check for broken links, unreachable targets, and pages with no inbound links. Evaluate multiple real-world routes from problem to explanation, work example, cost, and contact. Determine the number of links by benefit, not by a fixed quota.
Is it necessary to link from each article to all others?
No. Choose materials that help in the current scenario. An excessively identical list makes it difficult for the reader to choose.
