Let’s get into it.

Evolution of SEO and Updates

SEO has been around for more than 25 years. The first website was created in 1991 by Tim Berners-Lee. At that time, there was no Google, no ranking system, and no competition. Websites were just plain pages with basic information.

The term Search Engine Optimization (SEO) first appeared in the mid-1990s. It is believed that Bob Heyman, a digital marketer, coined the term when a client wanted their website to rank higher on search engines.

In those days, getting a website to rank was simple. Keyword stuffing and spammy backlinks were common tricks. People would repeat the same words multiple times, and search engines weren’t smart enough to tell the difference between useful content and manipulation.

Things changed as search engines got smarter.

Google Search Algorithm Updates

Google keeps updating its search algorithm to improve results. These updates help show useful content while filtering out low-quality sites. Here are some major updates that changed SEO over the years.

1. Panda (2011)
2. Penguin (2012)
3. Hummingbird (2013)
4. RankBrain (2015)
5. BERT (2019)
6. Page Experience Update (2021)
7. MUM (Multitask Unified Model) (2021)
8. Helpful Content Update (2022 – Ongoing)

Panda (2011)

Panda targeted low-quality content. It penalized sites with thin content, duplicate pages, and keyword stuffing. Websites with original and useful content ranked better.

Penguin (2012)

Penguin focused on backlinks. Before this update, websites ranked by getting thousands of low-quality links. Penguin penalized sites that used spammy links and unnatural link-building tactics.

Hummingbird (2013)

Hummingbird helped Google understand search intent. Instead of just matching keywords, it looked at the meaning behind words. This update improved search accuracy.

RankBrain (2015)

RankBrain introduced machine learning. It helped Google understand complex searches and user behavior. Websites with clear and valuable content ranked better.

BERT (2019)

BERT improved natural language understanding. It helped Google process long-tail keywords and conversational searches. This made search results more relevant.

Page Experience Update (2021)

This update made user experience a ranking factor. Google started considering page speed, mobile-friendliness, and Core Web Vitals.

MUM (Multitask Unified Model) (2021)

MUM helped Google understand images, videos, and different languages. It made search results more detailed and accurate.

Helpful Content Update (2022 – Ongoing)

This update prioritized people-first content. It penalized sites that focused on SEO tricks instead of real value.

Google keeps refining its algorithm to improve search results. Websites with useful and reader-friendly content always perform better.

Old SEO Strategies

As we already saw in the evolution of SEO, old SEO methods were a mix of black hat, white hat, and grey hat SEO. Many websites ranked using shortcuts instead of quality content.

Here are some of the old SEO strategies that worked back then.

• Buying Bulk Backlinks – Websites bought thousands of links from random sites. More links meant a higher ranking, no matter where they came from.
• Keyword Stuffing – Pages were filled with the same keyword over and over. It didn’t matter if it made sense. If “best shoes online” was the keyword, you’d see it 50 times on a page.
• CTR Boosting – Fake clicks were used to fool Google. Bots or click farms made it look like a page was popular, pushing it up in rankings.
• Exact Match Domains (EMD) – If you wanted to rank for “cheap laptops,” all you had to do was buy cheaplaptops.com. Google gave these domains an instant boost.
• Hidden Text and Links – Keywords and links were hidden in white text or behind images. People couldn’t see them, but search engines could.
• Spun Content – Software took an article and rewrote it in different words. The result? A jumbled mess that made no sense but tricked search engines.
• Link Exchanges and PBNs – Websites made deals to swap backlinks. Some even built private networks of fake sites just to create links.
• Over-Optimized Anchor Text – Every backlink used the exact same keyword. If a site wanted to rank for “best smartphones,” all its backlinks would say just that.
• Clickbait and Misleading Titles – Titles were written just to get clicks. You’d click on “Shocking Secrets About SEO!” only to find basic tips you already knew.

For a while, these tricks worked. But once Google got smarter, websites using them lost rankings overnight.

New SEO Strategies

SEO isn’t about tricks anymore. Google has evolved, and so have its strategies. Now, it’s all about quality, relevance, and user experience. Let’s see what works today.

• AEO (Answer Engine Optimization) – It’s not just about ranking anymore. Google wants direct answers. Optimizing for featured snippets, FAQs, and voice searches helps you appear at the top. Learn What is Answer Engine Optimization (AEO).
• E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) – Google now looks at who’s giving the information. A website with real expertise and credibility ranks better than random content.
• Paid SEO (Search Ads & Sponsored Listings) – Organic ranking takes time. Many businesses use paid ads on Google and social media to get immediate visibility.
• Mobile-Optimized Sites – Most users browse on their phones. A website that loads fast and looks good on mobile ranks better.
• User Experience (UX) Matters – Google watches how people interact with a site. If they leave too fast, rankings drop. Easy navigation and engaging content keep visitors around.
• Natural Backlinks – Forget buying links. Google values backlinks from real, high-quality sources like blogs, news sites, and industry leaders.
• AI-Generated Content (With Human Touch) – AI helps speed up content creation, but human editing makes it valuable. Google prefers well-written, informative content over robotic text.
• Schema Markup & Structured Data – Websites now use structured data to help search engines understand content better. It improves rankings and helps with rich snippets.
• Video & Visual Content Optimization – Videos rank too! Google favors pages with engaging videos, images, and interactive elements.

SEO has shifted from shortcuts to real, long-term strategies. If you focus on quality and user experience, your rankings will follow.
