Ranking Factors

There are a lot of ranking factors in SEO. Add up what the industry has documented over the years and you land somewhere north of 200 signals, and working on all of them is a full-time job for a team. So the useful question is not how many factors exist, but which ones decide whether a page can reach the top of the results at all. Below are the seven that carry the most weight in our own work, and what each one asks of you in practice.

1. Links

All else being equal, backlinks are still one of the strongest signals there is. A link is a recommendation: another site pointing at yours and saying, in effect, this one knows what it is doing. In a study of roughly 12 million search results, the average number one URL had 3.8 times more backlinks than the pages ranking second to tenth for the same query. That gap is not subtle.

A link is not just a link, though. If you run a restaurant, a link from a food critic is worth more than one from a book critic, even if the book critic is better known. Relevance, authority and trust have to hold together, and how to earn links that manage all three is the subject of link building. Note also that who you link to counts: citing strong sources shows you did the research and can back your claims.

The counterpart is worth stating once. Link schemes are named explicitly in the search engines' spam policies, the detection keeps improving, and cleaning up after a penalty is slow work that produces nothing new.

2. Search intent

There was a time when you could beat competitors by filling a page with the keyword. That produced keyword stuffing, and pages that read like a list of synonyms strung together. It looked ridiculous to a human being and worked anyway. It does not work now: with Hummingbird, RankBrain and everything built on top of them, search engines weigh meaning above individual words.

Search intent is what somebody is actually after when they type a query, and the fastest way to read it is to look at what already ranks. A single extra word changes everything. "Baby clothes" wants a shop, "which baby clothes" wants a guide. Two queries, two entirely different pages.

If your page misses the intent, it does not reach the top, no matter how many links you built or whether the exact phrase appears in the heading. Getting this right at scale is what keyword research is for.

3. Content that covers the subject

Depth is measurable, and the measurements are consistent. The average page ranking first carries well over 1,400 words, and long-form content earns around 77% more backlinks than short content covering the same ground. What correlates is not word count for its own sake, though. It is coverage: whether the page answers the question and the three questions that follow it.

Two things follow. First, content is never finished. Intent shifts, new information arrives, and a good post from three years ago quietly becomes a bad one. Keeping pages current is itself a positive signal, because it shows somebody is still responsible for the page. Second, credibility has to be visible on the page, which is the whole argument of E-E-A-T. A working rule for the maintenance half: update or delete content that gets no traffic.

4. Titles, headings and metadata

HTML is the building material of the web, and a handful of tags do most of the work.

The page title is used by browsers, by search engines and by anyone deciding whether to click. Optimize it for the primary term and for your brand, and note how consistent the pattern is: between 65% and 85% of top performers for a given keyword have that exact keyword in the title tag. Know where the limit sits, though. There is little correlation between the keyword in the title and climbing within page one. It helps you qualify for the first page, and from there the leverage moves elsewhere.

The meta description is not a direct ranking factor, and it decides your click-through rate, which is reason enough to write it deliberately. Both are covered in titles and meta descriptions.

Headings tell search engines which topics a page covers, and they let a skimming reader find the section they came for. Most people do not read to the bottom. Descriptive subheadings with the relevant terms in them serve the reader first and the crawler second, which is the correct order.

5. Core Web Vitals and page experience

Google's long arc has been from matching words to evaluating experience, and Core Web Vitals is the most concrete expression of it: LCP for how quickly the page shows something useful, INP for how quickly it responds when you act, CLS for whether it holds still while you read. The Core Web Vitals report in Search Console groups your URLs by problem rather than listing them page by page, which is what makes it actionable. Thresholds and the usual fixes are covered in Core Web Vitals.

The honest framing is that this is one signal among many, and a fast page with weak content does not outrank a strong one. It is still worth the work, because speed pays twice: better visibility, and measurably better conversion on the traffic you already have.

6. Structured data

Structured data is markup that states plainly what a page contains, and it is what qualifies you for the richer result formats: review stars, prices, availability, FAQs. For a shop, product markup is close to mandatory, because price and rating appearing directly in the results changes the click-through rate on your most commercial pages.

Most platforms handle a good deal of it through built-in functionality or plugins, and generating it at scale rather than by hand is the only sane approach. The formats and the common validation errors are covered in structured data.

7. Google Business Profile

If you have a physical location, a complete and current Google Business Profile is not optional. A very large share of searches carry local intent, and Google uses location when deciding what to show. The hungry parent with children in the car does not search for a burger in another city, and the same query in two towns returns two different sets of results. A well-maintained profile puts you in the local pack and in Maps, and it tells Google more about what your business does and who should see it. The full discipline sits in local SEO.

Ranking factors in AI search

The list above was written for classic search and holds up almost entirely for AI answers, because the systems selecting sources for a generated response are reading the same web. Authority through links, clear structure, unambiguous markup and visible credibility all carry over.

Two things behave differently. Position matters less than being quotable: a clearly stated conclusion near the top of the page is what ends up in an answer. And the crawlers that feed the models are stricter about rendering, so content that only appears after JavaScript runs may not be read at all. Where those differences come from is covered in AI search.

Takeaways

Do not be intimidated by the length of the list. There are more than 200 factors, more arrive every year, and their relative weight keeps shifting, which is why we spend real time testing rather than guessing. For your own work, the seven above cover most of the ground.
