Link building and brand building: what Google says and how to measure it
Google uses links as a signal and warns against building them to manipulate rankings. This lesson sets out what the documentation actually says, how to earn links, how to mark paid ones and how to measure links and brand demand in Search Console.

What Google says about links
Google states that it uses links as a signal when judging the relevance of pages and to find new pages to crawl (link best practices). Its ranking systems guide adds that PageRank, one of its core ranking systems from the start, has evolved and still forms part of them (ranking systems guide). Nothing in either page gives a number of links that is “enough”, and nothing makes any single link or score a guarantee.
The same documentation is blunt about the other side: links created mainly to manipulate rankings are link spam (spam policies).
Earn links, do not manufacture them
Google’s starter guide says that other sites linking to you happens naturally over time, and that word of mouth is among the most effective and lasting ways to promote a site (SEO starter guide). Practical routes that follow from this:
- Publish something worth citing: original data, a calculation, a tool or a clear explanation that other writers would rather link than rewrite.
- Be easy to find and credit: a stable URL, a named author and the method behind your numbers.
- Tell the people who care: a newsletter to subscribers who asked for it, a community where the topic belongs, a partner whose users benefit. The guide warns that overdoing promotion can harm a site.
What counts as link spam
The spam policies list, among other things: buying or selling links for ranking, excessive link exchanges, links with optimised anchor text in guest posts or press releases distributed on other sites, and links created by automated programs (spam policies). A paid or sponsored link is acceptable when it carries rel="nofollow" or rel="sponsored". Use sponsored for ads and paid placements, ugc for links users add and nofollow when neither fits; Google treats these values as hints (qualify outbound links).
Brand building is a different job
Google’s helpful-content guidance asks whether your site is well trusted or widely recognised on its topic, and whether people would bookmark, share or recommend a page (creating helpful content). It does not describe brand mentions as a ranking input, so treat brand work as demand you can measure, not as a switch. The measurable part is people searching for you by name.
How to measure it in Search Console
- See who links to you. The Links report lists top linked pages, top linking sites and top linking text, but it is a sample: tables are capped at 1,000 rows, data can be stale, it does not show whether a link is nofollow, and sites are grouped by root domain (Links report help).
- Track brand demand. In the Performance report, filter queries containing your brand name and compare equal periods. Rising brand clicks mean more people look for you by name.
- Judge a linked page against the site. Compare the page’s clicks with what the site trend alone would predict.
Illustrative example (invented numbers): a page had 1,200 clicks in the previous 28 days and 1,500 in the latest 28, while the whole site grew 5%. The site trend alone predicts 1,200 × 1.05 = 1,260, so the page gained 1,500 − 1,260 = 240 clicks beyond the trend. That is a signal to investigate, not proof that one link caused it.
Link building and brand, answered
How many links do I need?
Google gives no number. Documentation describes links as one signal, and quality and relevance matter more than count.
Are paid links allowed?
Yes, if they are qualified with rel="sponsored" or rel="nofollow"; unqualified paid links for ranking are link spam.
Does the Links report show every backlink?
No. It is a sample capped at 1,000 rows per table.
