What can harm your SEO?
Using AI, updating your website or adding pages does not automatically cause a penalty. But misleading content, attempts to manipulate search results and technical mistakes can put visibility at risk. Here is how to tell the problems apart and what to check before you make more changes.
Is it really a penalty?
Search engine optimisation (SEO) helps people find and understand your website through search. If you have changed your site and fewer people seem to be finding you, that is worth investigating. It does not tell you the cause.
- Manual action
- Google's human reviewers have identified a policy violation. Check the Manual actions report in Search Console for the issue and affected scope.
- Technical problem
- A page may be unavailable, blocked from indexing or incorrectly redirected. This is not the same as a spam penalty.
- Ranking or demand change
- Search performance can change with ranking systems, competition or seasonal demand. Compare the affected pages and dates before deciding what to fix.
Google explains the first category in its Manual actions report guidance. Its traffic-drop guide covers other possible causes. An empty Manual actions report rules out a reported manual action, not every possible search problem.
SEO practices to be careful with
The following examples summarise practices covered by Google's spam policies. Violations can reduce visibility or remove pages from results.
Producing lots of pages without useful content
Scaled content abuse means producing pages primarily to manipulate rankings rather than help readers. The method, including AI, is not the deciding factor.
Buying links to manipulate rankings
Links arranged primarily for ranking manipulation are link spam. Paid advertising links are different when appropriately marked, for example with rel="sponsored".
Repeating keywords unnaturally
Keyword stuffing fills pages with words or numbers to influence rankings. Naming your service naturally is not the same thing.
Creating pages that only funnel people elsewhere
Doorway abuse includes substantially similar pages built for related searches that send visitors to a more useful destination.
Showing search engines and visitors misleadingly different content
Cloaking and deceptive redirects can violate the policies. Legitimate redirects when a page moves are different.
Practical check: ask whoever is doing the work to show you a sample before approving a large batch. Read it as a potential customer. Can you understand the service, find accurate answers and take a useful next step?
Using AI does not remove the need to check the work
You can use an AI tool to organise notes or help write a draft. You still need to know whether the finished page accurately describes your business.
Before publishing, check the service area, credentials, prices, examples and any claims about results. Remove invented projects or customer stories. If nobody in your business can stand behind a sentence, do not publish it just because it sounds convincing.
Bing specifically warns that automatically generated content at scale without adequate oversight, quality control or editorial review may be excluded from indexing. See Bing's Webmaster Guidelines. Do not assume Google's reporting or review process applies identically to Bing.
Illustrative example: a decorator expanding their website
A decorator wants to explain interior painting, exterior work and the areas they cover. A useful brief starts with those real services, the questions customers ask and genuine work they can show. Generating a page for every nearby town before gathering that information gives the owner far more content to check, without necessarily answering more customer questions.
We already cover how to plan those pages in our service and location pages guide. You do not need a separate article for every variation of the same question.
A website rebuild can introduce ordinary technical mistakes
A new design can look better while an old service link stops working. Before launch, make a list of your important existing page addresses and decide what should happen to each one.
- Changed addresses: map an old page to its relevant replacement rather than sending every old link to the homepage.
- Development settings: check that pages intended for search do not retain a
noindexinstruction, which tells search engines not to include them. - Missing information: check that useful service details and internal links have survived the rebuild.
- Enquiry routes: test the phone link, contact form and confirmation process on a mobile. A broken form can reduce enquiries even when search visibility has not changed.
Google's site-move guidance explains redirect mapping and checking development restrictions. These are implementation checks, not evidence that your business has been penalised.
What to check if visits or enquiries fall
Start with a small investigation rather than changing the whole site again.
- Confirm what fell. Was it search impressions, clicks, recorded visits or actual enquiries? Check that you are viewing the correct property and dates, and whether tracking changed.
- Find the affected pages. Look at important service pages separately. Compare relevant search terms, devices and countries rather than relying only on a site-wide average.
- Check timing. Note recent launches, address changes and content edits. Compare longer periods and seasonal patterns where you have enough history.
- Check access and alerts. Inspect important URLs in Search Console and review Manual actions and Security issues. Use Bing Webmaster Tools for Bing's own indexing information.
- Fix the problem you can demonstrate. Record the change and monitor it. Do not assume a different title will repair a blocked page or that deleting articles will resolve a broken form.
This sequence follows the diagnostic approach in Google's traffic-drop guidance, with enquiry checks added for service businesses. A change happening just before a drop is a clue, not proof that it caused it.
If Google reports a manual action, follow the instructions for that issue, correct the affected work and request a review through the report when appropriate. Google explains the process in its manual-action help. There is no sensible blanket recovery deadline to promise.
Connect the problem to the work you want to win
Losing visitors to a service page could affect enquiries. But a percentage fall in traffic does not automatically mean the same fall in sales or profit.
Look at the enquiries associated with the affected pages or channels where that information is available. Were they in your area? Did they become conversations, surveys or quotes? Were quotes still pending? Your own records will tell you more than an alarming industry-wide loss estimate.
Keep search performance and sales handling in the same conversation. If suitable enquiries arrive but nobody follows them up, that needs attention too. Our lead qualification guide helps you decide which details to record.
Before your next website update
- Keep a recoverable copy of the current site and a dated list of planned changes.
- Check factual claims and review a sample before producing more pages.
- Give each new page a clear purpose for a real visitor.
- Map changed addresses and check important internal links.
- Confirm which pages should be indexable and which should remain private drafts.
- Test the mobile enquiry route and confirm who receives submissions.
- Record a search-performance baseline and check the important pages after release.
For ongoing care, a short weekly check for alerts, unexpected changes and broken enquiry routes can be useful. Review trends over a longer period, especially if your site has little traffic. This is a suggested routine, not a requirement to rewrite pages every week.
Get clear on what needs attention
You do not need to be frightened of improving your website. You need to know what is changing, why it should help and how you will check the result.
