In the first week, fix what stops your site being read, then what stops it being found, then what stops it being understood. After that, publish. Most new SaaS sites already pass the technical checks: 74.4% of the 313 we checked had all six basics. For most founders the week is better spent on pages than on settings.

Key facts

  • 233 of 313 new SaaS websites (74.4%) had all six technical basics in place when we checked on 28 September 20261.
  • 29 of 313 new SaaS home pages (9.3%) had fewer than 50 readable words without JavaScript1.
  • 26 of 313 new SaaS home pages (8.3%) had no H1 heading in the HTML1.
  • Google says a sitemap is most likely to be needed when a site "is new and has few external links to it"4.
  • Google's thresholds for a good page experience are LCP within 2.5 seconds, INP under 200 milliseconds, and CLS under 0.111.
  • Google stopped showing FAQ rich results on 7 May 202614.
  • Google says llms.txt files "will neither harm nor help" visibility in Google Search15.

The week at a glance

DayQuestionMain check
1Can the site be read?Your headline is in the page source
2Can the site be found?robots.txt, sitemap, canonical tags, no stray noindex
3Does the site say what the product is?Title, H1, description, pricing page
4Which AI crawlers are allowed in?A deliberate rule for each
5Is the site fast enough?Core Web Vitals on a phone
6What will a buyer compare you with?One comparison page
7What do you know that nobody else does?One article with your own numbers

If your site passes days 1 to 5 on the first look, move on to day 6.

Day 1: can the site be read?

Open your home page, view the page source, and search for your headline. If it is there, crawlers can read the page. If it is missing, the page is built in the browser and this is the first thing to fix.

In our check, 29 of 313 home pages (9.3%) had fewer than 50 readable words in the HTML. Among sites set up as Vite single page apps the share was 33.3%1.

This check comes first because the rest of the week depends on it. Vercel and MERJ reported in December 2024 that none of the major AI crawlers rendered JavaScript2. Google does render it, and still advises that server side rendering or pre-rendering "is still a great idea"3.

Run the same test on your pricing page and one other page. The tests and the fixes are in Can Google and AI assistants read a site built with AI tools?.

Day 2: can the site be found?

Day 2 has four checks.

robots.txt. Visit yoursite.com/robots.txt. You should see a short text file. 24 of the 313 sites we checked (7.7%) had no valid robots.txt file1.

Make sure the file does not block the whole site, which is a common leftover from development. Google notes that robots.txt controls crawling and "is not a mechanism for keeping a web page out of Google"5.

Sitemap. Visit yoursite.com/sitemap.xml. 28 of 313 sites (8.9%) had no sitemap1.

Google says a sitemap is most likely to be needed when a site "is new and has few external links to it", which describes every product in its launch week4. Submit it in Google Search Console.

Canonical tags. Each page should name its own address as the canonical one. 30 of 313 home pages (9.6%) had no canonical tag1. Google treats redirects and canonical tags as strong signals for which address to index6.

Stray noindex. Search the page source for "noindex". One of the 313 home pages we checked told search engines not to index it1. It is rare and it is fatal, so look.

Day 3: does the site say what the product is?

Read your home page as a stranger would, then check five things.

  1. Title. Every site in our check had one, and 9 had a title under 20 characters, which is usually just the product name1. Add what the product does. Google builds the title it shows from several sources, and your title tag is the one you control7.
  2. H1. One heading that says what the product is. 26 of 313 home pages (8.3%) had no H1 in the HTML, and 9 had more than one1.
  3. Meta description. 310 of 313 sites had one1. Google builds its snippets mainly from the page content and sometimes uses the description8. Write one that states what the product does and who it is for.
  4. A plain sentence. Near the top of the page, one sentence naming the product, what it does, and who it is for. Write it so that it still makes sense when quoted alone.
  5. A pricing page. 113 of 313 sites (36.1%) had no pricing page we could find1. If your prices are public, give them a page of their own with the numbers in the HTML.

Google states no character limit for titles or descriptions. It truncates what it shows to fit the screen78. Write for sense and keep the important words near the front.

Then structured data. Add Organization markup to the home page. Google says it helps identify an organisation, and it has no required properties9.

Add SoftwareApplication markup only if you can fill it in honestly. To be eligible for a rich result, Google requires the name, a price, and a rating or review10. If you have no real reviews yet, leave the rating out.

Day 4: which AI crawlers are allowed in?

Decide on purpose. The companies behind the main assistants run separate crawlers for separate jobs, and robots.txt controls most of them.

CrawlerRun byWhat it is forControlled by robots.txt?
GPTBotOpenAICollecting content to train modelsYes16
OAI-SearchBotOpenAIChatGPT search resultsYes16
ChatGPT-UserOpenAIFetching a page when a user asksRules may not apply16
ClaudeBotAnthropicCollecting content to train modelsYes17
Claude-SearchBotAnthropicSearch qualityYes17
Claude-UserAnthropicFetching a page when a user asksYes17
PerplexityBotPerplexityPerplexity search resultsYes18
Perplexity-UserPerplexityFetching a page when a user asksGenerally ignores the rules18
Google-ExtendedGoogleA control for Gemini training and groundingYes19

Two details are easy to miss. Google-Extended is a control token and not a crawler, and Google says it "does not impact a site's inclusion in Google Search"19. And a site that opts out of OAI-SearchBot will not be shown in ChatGPT search answers, according to OpenAI16.

For a new product that wants to be found, the sensible default is to allow the search and user crawlers. Whether to allow the training crawlers is your decision.

Allowing the search and user crawlers is what most new products do already. In our check, 8 of 313 sites (2.6%) blocked any AI crawler from the whole site1.

Any crawler you haven't named is allowed by default. You only need a rule to keep one out.

Day 5: is the site fast enough?

Test your home page on a phone connection with PageSpeed Insights and look at three numbers.

MeasureWhat it measuresGood
LCPHow quickly the main content loadsWithin 2.5 seconds
INPHow quickly the page responds to a tapUnder 200 milliseconds
CLSHow much the layout jumps aroundUnder 0.1

Those are Google's thresholds11. Google confirms that "Core Web Vitals are used by our ranking systems" and gives no weighting, so nobody can tell you what a faster page is worth in rankings12.

Most of the web falls short. The 2025 Web Almanac found that 48% of mobile pages passed all three in June 202513.

On a new SaaS site the usual causes are large images, fonts that load late, and scripts that run before the page appears. Fix the largest image first.

Day 6: what will a buyer compare you with?

Write one comparison page. 146 of the 313 sites we checked (46.6%) had no comparison or alternatives page at all1.

Pick the competitor your buyers mention most. Build a table of facts from their own pricing page, date it, and write an honest verdict on who should choose which. The comparison and alternatives pages every SaaS needs has the structure.

Day 7: what do you know that nobody else does?

Write one article around something of your own. It could be a number from your product, a test you ran, or a problem you solved and how you solved it.

127 of 313 new sites (40.6%) showed no blog or articles section1. Google's guidance for AI search asks site owners to focus on unique content20. The evidence on what assistants recommend points the same way, and we set it out in How AI assistants choose which products to recommend.

Pick a subject no other product in your category could have written about.

What can you skip?

Four things that take time and have no measured benefit.

SkipWhy
Adding an llms.txt fileGoogle says it will "neither harm nor help" in Google Search15. 167 of the 313 sites we checked already had one1
Adding FAQ markup for rich resultsGoogle stopped showing FAQ rich results on 7 May 202614
Trimming titles to 60 characters and descriptions to 155Google states no limit for either78
Dynamic renderingGoogle calls it "a workaround and not a recommended solution"21

If you already have an llms.txt file or FAQ markup, leave them. They do no harm. A visible questions section is still useful to readers.

What comes after the first week?

A routine. After the first week, visibility is built by steady work: a new page most weeks, facts kept current, and the product described in more places.

The full check that these figures come from is in We checked 313 new SaaS websites.

Questions

What is the first thing to check on a new SaaS website?

Whether the page content is in the HTML. View the page source and search for your headline. 9.3% of the new SaaS home pages we checked had fewer than 50 readable words without JavaScript.

Does a new website need a sitemap?

Yes. Google says a sitemap is most likely to be needed when a site is new and has few external links.

Should a new SaaS website block AI crawlers?

Not if you want assistants to find you. OpenAI says a site that opts out of OAI-SearchBot will not be shown in ChatGPT search answers. Blocking training crawlers such as GPTBot is a separate choice.

Is there a character limit for title tags?

Google states none. It truncates titles and snippets to fit the device. Put the important words first.

Should I add an llms.txt file?

There is no measured benefit. Google says the file does not affect Google Search, and Ahrefs found that 97% of llms.txt files received no requests in May 2026.

Does FAQ schema still work?

Google stopped showing FAQ rich results on 7 May 2026. A visible questions section is still useful for readers.
