A search engine friendly website can be found, understood and relied upon by Google (and all other engines) which means that real people will arrive at a site having an inbound link.
The first thing is it has to be crawl-able. This means search engines can crawl your pages without hitting error 404s, infinite loops or indexable content. A simple site structure, meaningful menus and an up-to-date sitemap all contribute. For help with Web Design Dublin, contact https://dublin.nettl.com/web-design
Second, it must be intelligible. Every page should have one primary topic with a clear purpose. Great headlines, clear page titles and copy in simple English help search engines connect your page to the right searches. More specific information is also useful, such as location and services provided (e.g. boiler servicing in Bristol) instead of simply saying something vague.
Third, it should be snappy and mobile compatible. Visitors do not stick around for long if pages load slowly or are difficult to use on a phone and that translates into slow performance in the long-run. Images should be compressed, layouts clean and buttons easily tappable.
Fourth, it needs trust signals. To demonstrate that you are a real business, search engines will look for an accurate contact information page (Name Address Phone Number), an About Us page explaining who/what your brand is, reviews and testimonials about the service.
Finally, a search engine friendly site is not obsolete anymore. Pages that are regularly updated with fresh, relevant content signal to search engines that your business is alive.
To sum up: good SEO is no magic trick. Making your site as concise, informative and easy to navigate for not just bots but also humans.
