What’s the most important thing you can do to make sure your site can show up in search results?
A bot-friendly website makes it easy for search engines to discover its content and make it available to users.
Crawling, or a visit from a bot to collect information, is the first step in the (long) process that ends with your site listed first in the search engine results pages. This step is so important that Google representative Gary Illyes believes it needs all caps:
We [Google] don’t do a good enough job getting people to focus on the important things. Like CREATING A DAMN CRAWLABLE SITE

A crawlable site lets search engine bots carry out their basic tasks:
The steps you can take to make your website crawlable must address all of these aspects.
Googlebots follow website instructions to bots. These instructions can appear in different locations:
Pages or site sections that are forbidden to bots are not crawlable because they are not accessible to Google.
When providing instructions for bots, keep in mind that Google regularly crawls with the following bots:
You can see how your site’s robots.txt file targets these bots by using an SEO crawler that respects directives to bots and running a crawl with “Googlebot” as the bot user agent name.
Auditing your site for each page’s meta robots instructions is also straightforward: pages should appear on Google must allow Googlebots to crawl them.
Sites with page and server errors are effectively unavailable to bots (and users!) while the error is present. Recurring or systematic errors can also have a negative effect on SEO in general.
You can monitor your website’s errors through regular crawls and by correcting the pages with an HTTP status of in the 400s and 500s.
Site architecture designates the way a visitor, whether a user or a bot, can move from page to page using links on a website. This includes not only the links in your navigational menu, but also the links in the content of the page and all of the links in the footer.
Good site architecture design considers the following standards:
These three standards are based on how search engine crawlers behave:
Links from other pages on the same website help search engines establish the relative importance of a page on the website. This helps establish content as good content. In short, a page with more links pointing to it is often more important than a page with very few links pointing to it.
At the extreme end of the scale of unimportance is the orphan page, or a page with no links to it. Unless there are outside links to orphan pages, these pages are invisible to search engines. The key to making them crawlable is adding links to them from page that are already part of your site’s architecture.
Because of the gaps between when a page is discovered, when it is crawled and when links on the new page are crawled, pages that are far from key site entry points (notably: the home page) can take a long time to be crawled by search engines. The distance from the home page is referred to as page depth and can be reduced by adding links to deep pages from category pages and other pages that are close to the home.
There’s a gap between what modern browsers do and what Google does right now.

The technology used by web crawlers to access page content is currently based on Chrome 41 (M41). If you’re using an up-to-date version of Chrome in March 2019, you’re probably on a version of Chrome 72 or Chrome 73. While that’s a big gap, Google says they’re working on closing it.
This doesn’t mean that you can’t include rich media content such as Flash, Silverlight, or videos on your site; it just means that any content you embed in these files should also be available in text format or it might not be accessible to all search engines.

Dynamic rendering requires your web server to detect crawlers (for example, by checking the user agent). Requests from crawlers are routed to a renderer, requests from users are served normally. Where needed, the dynamic renderer serves a version of the content that’s suitable to the crawler, for example, it may serve a static HTML version. You can choose to enable the dynamic renderer for all pages or on a per-page basis.

There has been some discussion as to whether this amounts to cloaking, which is subject to penalties: it’s a way of providing non-identical content to users and to bots.
The objective is to ensure that your content can be viewed and interpreted by all visitors, whether users or bots. Some SEOs, such as Jan-Willem Bobink, argue instead for full SSR for SEO purposes.
You can verify how Google sees your page using the Inspect URL tool, available since January 2019 in the new Google Search Console:

If your website is crawl-friendly, you’ve won the first battle in SEO. Crawlable sites can be indexed, and indexed sites can be ranked. And ranked sites bring in leads.
A crawlable site considers bots’ nature and their limitations from its design through its monitoring. It addresses issues such as:
If you’re interested in attracting visitors, gaining leads through digital marketing, or promoting products and services online, a crawlable site is the first step to success.
