SEO Guide for Practitioners: Technical, Content and AI Search

Pick the goal that matches your next decision, then read its order from the top. Each order sends you to the page that answers the next question, so you do not need to read the whole section at once.

Set traffic targets from the click loss on your own queries, not from one industry figure. Read each figure below as a separate study with its own design.

SparkToro, using Similarweb's desktop and mobile web panel, found that 68.01% of Google searches in the US ended without a click from January to April 2026. The same report gives 60.45% for 2024 from a different panel (Datos), and SparkToro's 2024 study put the 2024 figure at 58.5% on Datos data, so treat the rise as a direction, not a precise change.

Pew Research Center measured clicks in a browsing panel of 900 US adults. Users who saw a Google AI summary clicked a traditional result in 8% of visits, against 15% of visits without one. Pew counted 68,879 unique Google searches in March 2025, and 12,593 of them produced an AI summary.

Ahrefs found that for position 1, AI Overviews correlate with a 58% lower average click-through rate. The study compared 150,000 keywords with an AI Overview and 150,000 informational keywords without one, using Search Console data from December 2023 and December 2025.

Google counts clicks from AI features in normal Search Console traffic, under the Web search type. Search Console does not report those clicks on their own, so you cannot read them from a separate line.

Use these figures as a range, not a forecast. The Pew design, the Ahrefs design and the SparkToro panel measure different things, so do not blend them into one percentage. Use one study's pair of figures when you quote a comparison, and name its panel.

Group your queries by intent, track each group's click trend over time, and set targets for each group rather than for the whole site. A site-wide average hides the groups that lost the most clicks.

The SEO fundamentals page covers zero-click and AI Overview impact, search intent and time to rank in depth. Read it before you set a traffic goal for a new section.

Fix eligibility before you start content work. A page that Google cannot crawl, index or load well gains little from better copy. Check the items below in order: links, indexing scale, mobile parity, then speed.

Google's Core Web Vitals thresholds for a good page are a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint of 200 milliseconds or less, and a Cumulative Layout Shift of 0.1 or less.

Google assesses these at the 75th percentile of page loads, segmented across mobile and desktop devices. A fast test on one device does not show whether the field data passes, so test the templates that get the most mobile traffic first.

Google can only follow a link when it is an anchor element with an href attribute. Menus, filters and pagination built only from buttons or scripts give Google no link to follow, so the pages behind them can stay hidden.

Check the rendered links on your main templates. Compare what a crawler sees with what a visitor sees, and fix any control that does not produce a real link.

Google indexes and ranks from the mobile version of a site, crawled with the smartphone agent. Mobile and desktop must carry the same content and the same structured data.

Audit mobile pages for text, links and schema that the desktop page has but the mobile page drops. Google indexes the mobile version, so a block that appears only on desktop does not count toward the indexed page.

Crawl budget work matters at scale. Google's guidance is aimed at sites with 1 million+ unique pages that change about weekly, and at medium or larger sites with 10,000+ unique pages that change daily.

Google also lists many URLs reported as Discovered - currently not indexed as a sign that crawl capacity needs attention. Google describes these figures as rough estimates, so treat them as a prompt to look, not as a rule.

Below that scale, Google points you to a current sitemap and the Page Indexing report instead of crawl budget work. Sitemaps are not required, and some changes take effect within hours while others can take months.

The image SEO page covers largest contentful paint images and layout shift in depth. The complete technical SEO checklist lists the audit steps for each check in this section.

Decide which pages should exist before you write them. Google judges each page by its value to a reader, and it judges many pages together by why they were made.

Expect a long build. Ahrefs found that only 1.74% of newly published pages reach the top 10 within a year, in a sample of 1 million random URLs its crawler found in September 2023.

Ahrefs also reports that the #1 ranking page in Google is on average 5 years old. Its sample covered about 1.3 million US keywords with the top 10 URLs for each, and it measured age from the first time its crawler saw each URL.

Google says its ranking systems prioritize helpful, reliable information created to benefit people. Of the E-E-A-T aspects, Google says trust is the most important.

Google suggests disclosing AI or automation where a reader might ask how the content was created. Put the disclosure where the question comes up, not in a footer.

Scaled content abuse is when many pages are generated mainly to manipulate rankings, however they are made. Google's spam policy gives generating many pages with generative AI tools, without adding value for users, as an example.

The same spam policy covers third-party content published on a host site mainly because of that host's already-established ranking signals.

Google's guide on optimizing for generative AI features names unique, compelling and useful content as its most important recommendation.

For each cluster, write down the one question that only this page answers. If you cannot write that question, merge the page into a stronger page on the same topic.

Plan clusters on the SEO content strategy page. For template sets, read the programmatic SEO page, then run the programmatic pre-launch checklist before you publish.

Check your link plan against Google's spam definitions before you pay for, trade or place any link. The test is purpose: a link built primarily to manipulate rankings is link spam.

Google's spam policy defines link spam as links created to or from a site primarily to manipulate search rankings. Buying or selling links for ranking purposes is link spam, and so are excessive link exchanges.

Optimized anchor text in articles, guest posts or press releases distributed on other sites also counts as link spam. Review every guest post and press release for the anchor text you asked for, not only for the placement.

Paid links are acceptable when they carry a nofollow or sponsored attribute on the link. Mark every paid placement and sponsorship that way before it goes live.

Measure link work by the pages it helps rank and the referral traffic it brings, not by link count alone.

The off-page SEO guide covers outreach, prospecting and when a disavow file is justified. Part of that guide sits behind a Pro plan.

Do the classic SEO work first. Google says optimizing for generative AI search is still SEO, so the same eligibility and content rules apply to AI features.

Google's guide on optimizing for generative AI features, last updated July 10, 2026, says optimizing for generative AI search is optimizing for the search experience, and thus still SEO.

Google says you do not need to create new machine readable files, AI text files, markup or Markdown to appear in Google Search.

Google also says that creating llms.txt will neither harm nor help your visibility or rankings in Google Search, because Google Search ignores those files.

Structured data is not required for generative AI search, and you do not need to add any special schema.org markup for it.

Google's AI features page says there are no additional requirements to appear in AI Overviews or AI Mode, and no other special optimizations are necessary. The page must be indexed and eligible to be shown with a snippet.

Put the effort into content that is unique, compelling and useful, on pages that Google can crawl and index.

For assistants other than Google, such as ChatGPT and Perplexity, do not assume Google's rules carry over. Read the search ecosystem optimization page for those platforms.

The GEO vs SEO guide covers how optimizing for AI answers differs from classic SEO and how to earn citations. Read it after the eligibility checks above, so the AI work starts from pages that already pass them.
