A Guide to Migrating From Google Site Search

Last call for Google’s site search tools

Google announced in 2016 that the Google Search Appliance (GSA) would be sunset, and that it would no longer sell GSA hardware. Licenses and support for the remaining appliances ended in 2019, effectively ending the viability of this widely used search technology.

It wasn’t the last change. Google also retired Google Site Search in 2018 and shut down the Site Restricted JSON API in January 2025. Now Google Programmable Search is being narrowed too: engines that search more than 50 domains or the whole web, and anything built on the Custom Search JSON API, need a new home by January 1, 2027.

Migrating away from a Google search tool may be a scary proposition, but it’s also the perfect time to re-evaluate which features are important to your organization. It also creates an opportunity to identify new features and functionality you could be using and benefiting from, which weren’t available with Google’s tools. Overall, this can be an advantageous upgrade from your existing solution, if you take the proper steps to evaluate your organization’s needs and technology requirements.

The first step to taking advantage of this opportunity, and creating a smooth transition to a new search platform, is to create a clear migration plan for your organization. Here’s how.

How to migrate from Google site search

1. Needs assessment. Gain a clear understanding of what features and functionality your team is using (or not using) with your current Google search setup. Then take a closer look at what new functionality is available with today’s solutions. Are there opportunities to increase relevance, save time, or create more efficiency? Don’t restrict this to your IT team. Talk to your content owners, your marketing people and, if possible, your search users to understand how you can serve all of them better.
2. Evaluation. Once you have a clear idea of what you’re looking for, create a shortlist of replacement solutions. Test them and see how well they map to your unique needs. Evaluate how easy they will be to migrate to, how much time and expense the migration will involve, how much support they offer you, and what features and functionality are offered right out of the box.
3. Configuration. Once you’ve selected a replacement, it’s time to start configuring it to your needs. Especially with modern SaaS search solutions, you’ll receive a lot of functionality built right in, which should reduce the time you need to spend building from scratch. You should also be able to port over some of your existing configuration and settings, like your synonyms.
4. Launch. Now comes the fun part! Validate all your settings, run quality control tests to make sure your new search is working to spec and delivering relevant results, and check that your index is up to date. Then you’re ready to go live on your public-facing website and/or intranet. Congratulations, you’ve successfully migrated to a new site search platform!
5. Maintenance. For the next few weeks, keep a close eye on your search to catch any remaining bugs from the migration. Once you’re satisfied that everything is running smoothly, keep paying close attention to your search analytics. There’s a wealth of information to be gained from them! Ongoing support and maintenance are also important, though with a SaaS platform there isn’t much more for you to do, as security patches and updates are pushed through by your provider automatically.

Key considerations when selecting a replacement

The most critical functions of your search platform are, of course, giving website visitors or intranet users an easy way to search, find and navigate content, and giving your team the ability to learn from and optimize content based on site search data.

When replacing your Google search tool, look for solutions that can not only match your existing functionality, but surpass it by improving the experience in a meaningful way.

Effective content delivery

Going beyond efficient content indexing and the delivery of relevant results, make sure your new site search solution is aligned with your overall digital content strategy, and is equipped with enough assistive technology (intelligent autocomplete, synonyms, typo tolerance), automation (AI and machine learning) and business intelligence (behavioral insights and analytics).

Some key site search features to look out for:

Why this functionality matters

Let’s look at how this functionality would work in a real-world replacement scenario.

For example, for an educational institution, the search bar and search results pages (SERPs) should be integrated into the overall design of the website, and should allow configurations that let visitors search for:

A search within each of these categories can then be made more dynamic and efficient with machine learning that powers intelligent autocomplete, with synonyms that make searches within specialized academic vocabularies easier, and by letting visitors search across indexes.

When someone searches for a specific article in the physics department, for example, intelligent autocomplete would help them find the most relevant article, while engine controls (if properly set up) keep dated news articles on a similar topic from appearing at the top of the results page.

Personalization is also important. If your users are logged into an intranet or learning management portal, you should be able to personalize their search results. For example, a student studying molecular biology could see promoted content from their major when using the search function.

Search analytics and insights

An often overlooked function of a search platform is the ability to deliver critical information to marketing and content staff. Search analytics can be used to optimize both search performance and your overall content strategy.

Search analytics can create strategic insights that guide your marketing and content strategy. And because they can be predictive, search analytics can help you prepare for upcoming events in your market that might otherwise go unnoticed. For instance, by analyzing trending search terms, your team can begin to predict corresponding trends in customer behavior. By combining website analytics (such as Google Analytics) and site search analytics, content owners can identify how their audiences behave online, what their needs are, and what gaps exist in their content.

Launch and maintenance: setup and support considerations

Things have moved on since the Google Search Appliance was released in 2002, and you shouldn’t need a long development process to set up a customized, modern site search solution. Unlike hardware that is expensive, high-maintenance and quickly falls out of date, modern SaaS site search solutions are secure and configurable to your needs. The best part? Most of their functionality works right out of the box.

When selecting a search solution, the first consideration is making sure it’s compatible with your CMS, and can be integrated with other useful tools like Google Analytics or Siteimprove. You should also evaluate how difficult, expensive or time-consuming the setup is going to be. For example, building from scratch on a platform like Solr, Lucene, Azure or Elastic can be an extremely time-consuming and expensive proposition.

Support and training for your new solution are also critical. Lock down a commitment on the support you’ll receive from your new search provider, both for setting up your search platform and for ongoing support and maintenance. Google offered little in the way of human support for its search products, and some providers charge extra even for minor support or maintenance requests.

Selecting the right platform: why Cludo is a strong Google site search replacement

Cludo is AI-powered site search, built for content-heavy websites, that puts you in control of your search and helps your organization get more value out of its content. Cludo goes far beyond what Google’s site search tools offered, with more control over your entire search experience, actionable dashboards and analytics, and better customer support.

Easy to configure and use

Cludo is powerful for developers, yet very much built for marketing and communications teams. There are no specific skills needed to set up or maintain the product, unless you use our API to build a custom search, in which case experience working with an API is needed.

While search has traditionally been managed by web development teams, Cludo is built to be easily managed by marketing teams with little to no developer involvement. For example, content and website owners can work directly from Cludo’s analytics dashboard to optimize search, boost results and add synonyms, with no technical training needed. It includes all the features you’d want in a search solution: full control over relevance, banners, content boosting, AI ranking, actionable analytics, an intuitive dashboard and much more, in an easy-to-use package.

Cludo’s implementation and customer success teams provide training to get you started, and we’ll work with your team to implement a search experience that fits seamlessly with your website’s design and overall digital experience.

Smarter relevance, with you in control

Cludo works beautifully out of the box, and it’s also entirely customizable. Cludo AI Search combines keyword and vector search, so it understands what visitors mean, not just the exact words they type. On top of that, you can apply boosting settings to a range of criteria engine-wide, or more precisely with page rankings.

You can boost based on almost anything: path, title, category, domain, ID, description, or field value comparison. You can also add custom fields if there’s additional metadata you want to boost by. And with AI ranking, Cludo automatically improves the order of results based on how visitors actually use your search, on top of the boosts and page rankings you set yourself.

In addition, Cludo’s intelligent autocomplete is one of the most effective assistance tools available to site search users. It uses visitor behavior to predict what someone is searching for, delivering suggestions faster and creating a more efficient search experience. Other site search solutions base their autocomplete suggestions purely on content and tags, simply pulling from the indexed content on the site and guessing at what the user is typing. Cludo’s autocomplete is based on actual visitor behavior, which makes its suggestions more dynamic and accurate, because they’re based on what has actually worked for other visitors.

Illustrative example: suggestions based on what other visitors searched for and clicked.

Answers and insights, not just search

Cludo goes beyond site search. Unlike platforms that only focus on delivering content, Cludo covers the full cycle: delivering relevant content and direct AI answers, analyzing how your visitors interact with that content, and giving you the insights you need to keep improving.

Cludo helps you get more value out of your content, with insight into what content visitors want, whether it currently exists on your site or not, and how well your content is performing. This helps you create more valuable content and improve how it’s delivered.

It also saves your team time. Instead of digging through mountains of data, Cludo’s actionable analytics tell you exactly where your content gaps are, and what content matters most. Plus, if your content is solid and your search is optimized, it will also save your staff time answering requests for information.

Scalable and secure

Cludo is fully scalable in terms of the number of data sources, records, engines, indexing intervals, search volume and more. Our team partners with every client to establish their requirements, so we can right-size a package for them. The platform can also grow with your organization, adding more pages, searches or engines to any package if needed.

Cludo continuously monitors search performance and conducts regular penetration testing, and our customer success team will help make sure noticeable spam traffic isn’t counted against your yearly search volume.

Single sign-on (SSO) is also available within the platform. Security can be set per engine. For public-facing websites, a public engine will usually be enough, while internal (intranet) search requires an API key to access the content. If needed for an intranet, you can filter what each user can search via the API, creating role-based search. Audit logs are also available on request.

Quick setup and easy migration

When migrating from Google’s site search to Cludo, you don’t need to go through a long and complicated transition. There’s no hardware or software to install. You simply provide the domains to be crawled, and our crawlers will index all the pages and files on your website. If you choose to, you can bring over the synonyms you’ve already set up, and let our crawlers do the rest. Your current search keeps running while we set up.

Keeping the index up to date can be done in a few ways. If you have a sitemap, we can watch it for changes, which is much faster than recrawling thousands of pages, especially since much of that content doesn’t change often. We can also schedule crawlers to recrawl your sites at regular intervals, and our APIs let you push content updates to the index when you need to.

Cludo also has REST APIs for developers who want to build custom integrations or a fully custom search experience. Beyond requesting help from our support team as needed, we also suggest scheduling an API-specific training, so you’re comfortable using these resources.

What are my next steps?

With the January 1, 2027 Programmable Search deadline approaching, time is of the essence. If you don’t have a migration path plotted out yet, a great first step is to start researching alternatives. As we said before, this is the perfect opportunity to include input from your content and marketing teams, so your next site search platform is fully integrated into your overall digital and website strategy.

If you’re looking for help or guidance on moving off Google’s site search, or would like to future-proof your investment with a better view of where site search is headed, Cludo’s search experts are happy to give you the information and tools you need to make an informed decision.
