Maintaining your website's SEO
If your site is on Google and you're familiar with the fundamentals of SEO, there are more things you can do to improve how your site appears on Google. As you manage and maintain your website, you may come across more unique scenarios that affect Google Search. This guide covers more in-depth SEO tasks, such as preparing for a site move or managing a multi-lingual site.
Control how Google crawls and indexes your site
Read our guide to understand how Google Search works; if you don't understand the crawl/index/serving pipeline well, it will be difficult to debug issues or anticipate Search behavior on your site.
Be sure that you understand what canonical pages are, and how they affect crawling and indexing of your site.
Be sure that any resources (images, CSS files, and so on) or pages that Google is meant to crawl are accessible to Google; that is, they are not blocked by any robots.txt rules and are accessible to an anonymous user. Inaccessible pages will not appear in the Index Coverage report, and the URL Inspection tool will show them as not crawled. Blocked resources are shown only at the individual URL level, in the URL Inspection tool. If important resources on a page are blocked, this can prevent Google from crawling your page properly. Use the URL Inspection tool to render the live page to verify whether Google sees the page as you expect.
Use robots.txt rules to prevent crawling, and sitemaps to encourage crawling. Block crawling
of duplicate content on your site, or unimportant resources (such as small, frequently used
graphics such as icons or logos) that might overload your server with requests. Don't use
robots.txt as a mechanism to prevent indexing; use the
noindex tag or login
requirements for that. Read more about blocking access to your content.
Sitemaps are a very important way to tell Google which pages are important to your site, and also provide additional information (such as update frequency), and are very important for crawling non-textual content (such as images or video). Although Google won't limit crawling to pages listed in your sitemaps, it will prioritize crawling these pages. This is especially important for sites with rapidly changing content, or with pages that might not be discovered through links. Using sitemaps helps Google discover and prioritize which pages to crawl on your site. Read all about sitemaps here.
Internationalized or multi-lingual sites
If your site includes multiple languages, or is targeted at users in specific locales:
- Read about multi-regional and multi-lingual sites for high-level advice on how to manage sites that have localized content for different languages or regions.
- Use hreflang to tell Google about different language variations of pages on your site.
- If your site adapts the content of its pages based on the locale of the request, read how this can affect Google's crawl of your site.
Migrating a page or a site
On the occasion that you might need to move a single URL or even a whole site, follow these guidelines:
Migrating a single URL
If you move a page permanently to another location, don't forget
301 redirects for your
page. If the move is only temporary for some reason, return
302 instead to tell
Google to continue to crawl your page.
When a user requests a page that has been removed, you can create a custom
404 page to
provide a better experience. Just be sure that when a user requests a page that is no longer
there, you return a true
404 error, not a
Migrating a site
If you're migrating an entire site, implement all the
301 and sitemap changes you need, then
tell Google about the move so that we can start crawling the new site and forwarding your
signals to the new site. Learn how
to migrate your site.
Follow crawling and indexing best practices
- Make your links
crawlable. Google can follow links only if they are an
<a>tag with an
hrefattribute. Links that use other formats won't be followed by Google's crawlers. Google cannot follow
<a>links without an
hreftag or other tags that perform as links because of scripted click events.
rel=nofollowfor paid links, links that require login, or untrusted content (such as user-submitted content) to avoid passing your quality signals on to them, or having their bad quality reflect on you.
- Managing your crawl budget: If your site is particularly large (hundreds of millions of pages that change periodically, or perhaps tens of millions of pages that change frequently), Google might not be able to crawl your entire site as often as you'd like, so you might need to point Google to the most important pages on your site. The best mechanism for doing so at present is to list your most recently updated or most important pages in your sitemaps, and hiding your less important pages using robots.txt rules.
- Multi-page articles: If you have an article broken into several pages, be sure that there are prominent next and previous links for users to click (and that these are crawlable links). That's all you need for the page set to be crawled by Google.
- Infinite scroll pages: Google can have trouble scrolling through infinite scroll pages; provide a paginated version if you want the page to be crawled. Learn more about search-friendly infinite scroll pages.
- Block access to URLs that change state, such as posting comments, creating accounts, adding items to a cart, and so on. Use robots.txt to block these URLs.
- Review the list of which file types are indexable by Google.
- In the unlikely situation that Google seems to be crawling your site too much, you can turn down the crawl rate for your site. However, this should be a rare occurrence.
- If your site is still HTTP, we recommend migrating to HTTPS, for your users' security, as well as your own.
Help Google understand your site
Put key information in text, not graphics, on the site. Although Google can parse and index many file types, text is still the safest bet to help us understand the content of the page. If you use non-text content, or if you want to provide additional guidance about the content of the site, add structured data to your pages to help us understand your content (and in some cases, provide special search features such as rich results).
If you feel comfortable with HTML and basic coding, you can add structured data by hand following the developer guidelines. If you want a little help, you can use the WYSIWYG Structured Data Markup helper to help you generate basic structured data for you.
If you don't have the ability to add structured data to your pages, you might use the Data Highlighter tool, which lets you highlight portions of a page and tell Google what each section represents (an event, a date, a price, and so on). This is simple, but it can break if you change the layout of your page.
Follow our guidelines
If you have specific types of content on your site, here are some recommendations for getting them on Google in the best way:
- Video: Be sure to follow our video best practices to enable Google to find, crawl, and show results for videos hosted on your site.
- Podcasting: You can expose podcasts to Google by following these guidelines.
- Images: Follow our image best practices
to get your images to appear in Search. You can show additional information
about your image in Google Images by providing image rights metadata
on the image host page. To block an image from being indexed,
use a robots.txt
- For children: If your content is specifically for children, tag your pages or site as child-directed in order to comply with the Children's Online Privacy Protection Act (COPPA).
- Adult sites: If your site (or specific pages) contain adult-only content, you might consider tagging it as adult content, which will filter it in SafeSearch results.
- News: If you run a news site, here are some important considerations:
- If you have news content, be sure to read the Google Publisher Center help documentation.
- In addition, create a News sitemap to help Google discover content more quickly.
- Be sure to prevent abuse on your site.
- If you want to provide a limited number of views to visitors without a subscription or login, read about flexible sampling to learn some best practices about providing limited access to your content.
- See how to indicate subscription and paywalled content on your site to Google while still enabling crawling.
- See how to use meta tags to limit text or image use when generating search result snippets.
- Consider using AMP or Web Stories for fast-loading content.
- Other sites (for example, sites about businesses, books, apps, scholarly works): See other Google services where you can post your information.
- See if Google supports a Search feature specific for your content type. Google supports specialized Search features for recipes, events, job posting sites, and more.
Manage the user experience
Providing a good user experience should be your site's top goal, and a good user experience is a ranking factor. There are many elements to providing a good user experience; here are a few of them.
Google recommends that websites use HTTPS, rather than HTTP, to improve user and site security. Sites that use HTTP can be marked as "not secure" in the Chrome browser. Learn how to secure your site with HTTPS.
A fast page usually beats a slow page in user satisfaction. You can use the Core Web Vitals report to see your site-wide performance numbers, or PageSpeed Insights to test performance for individual pages. You can learn more about building fast pages on the web.dev site. Also consider using AMP for fast pages.
With mobile searches now exceeding desktop searches, it's important that your site be mobile-friendly. Google now uses a mobile crawler as the default crawler for websites. Read about how to make your site mobile friendly.
Read these additional pages about mobile usage on Google, including behavior on feature phones, how Google Discover works on mobile devices, and also guidelines about announcing any mobile billing charges clearly on your site to prevent warnings in Google Chrome.
Control your search appearance
Google provides many kinds of search result features and experiences in Google Search, including review stars, embedded site search boxes, and special result types for specific types of information such as events or recipes. See which ones are appropriate for your site and consider implementing them. You can provide a favicon to show in search results for your site. You can also provide an article date to appear in search results.
Be sure to read the articles on how to help Google provide good titles links and snippets. You can also restrict the snippet length, or omit it entirely if you wish. See how to use meta tags to limit text or image use when generating search result snippets.
If you are a European press publisher, tell Search Console.
