SEO 懶人包:Search On 2020 重點解析

Google Search On 2020

Search on 2020 於上週 10/15 舉辦了線上研討會,主要分享 Google Search 在今年的一些重點改變,筆者這邊就整理了 Search On 2020 懶人包,一起來了解一下近期即將帶來的搜尋引擎變革。

Google Search 於 1998 年問世至今已經 20 幾個年頭,如今 2020 年,他的地位可能不在是單純的搜尋引擎而是資訊的平台,你可以搜尋文字、搜尋影音、語音搜尋,甚至是 AR 擴增實境。此外今年的 COVID-19 新冠疫情,Google Search 也提供了公正公開的真實數據,傳遞正確的訊息。而在 2020,搜尋引擎更瞄準了日益繁複的搜尋需求,想針對特定的 Data Set 做搜尋?想搜尋 3D 立體的家具?腦海中浮現出一段旋律想知道歌名?這些搜尋需求,在不久的將來都可以透過 Google 搜尋引擎做到。

理解 NLP 自然語言

在 2019 年 Google 發表了 BERT (Bidirectional Encoder Representations from Transformers)演算法,透過搜尋引擎來分析句子的完整意涵,讓使用者獲得精確的解答。以下方 Google 提出的範例為例:

當用戶搜尋「如何知道我的窗戶是用 UV 玻璃」,在過去的搜尋引擎,Google 判斷用戶搜尋的主要 term 是「UV 玻璃」、「決策」,所以 SERP Top 1 是關於 UV 玻璃的相關實驗,而通過 BERT 演算法的判斷,他清楚知道用戶的搜尋意圖是想判斷家中窗戶是否有抗 UV,並且給出判斷的方式。 在 Google Search On 2020,Google 宣布將全面採用 BERT 搭配 Rank Brain 演算法來提供搜尋結果。(目前以英文為主)

拼字檢查

Google 表示,每天每十個用戶檢索搜尋,就有一個是拼錯字的,因為 Google Spelling algorithm 拼字演算法,可以校正用戶的錯字搜尋,給予正確的搜尋結果

針對段落排名

搜尋引擎再也不是僅尋找完整回答到你問題的頁面,往往你的問題僅出現在優質頁面中的某些段落。為了幫助使用者在茫茫網海中大海撈針,Google 將開始針對段落排名,目前這樣新的排名演算,將先實施 7% 左右的搜尋結果(一樣是英文語系優先),段落排名可以幫助優質的內容網頁(可能不是 100% 頁面都在講用戶搜尋的內容,但其中的一個段落清楚的回答到用戶問題)獲得更多爭取排名的機會

理解主題與次主題

AI 同時幫助 Google 理解主題及次主題,這代表 Google 搜尋引擎可以搜尋者的搜尋主要主題(意圖),以及衍生的次主題(意圖),以 Google 提供的範例來說,使用者搜尋廣義的詞「居家運動器材」,Google 除了提供居家運動器材結果,同時也會提供衍生的主題如「經濟實惠的運動器材」、「小型運動器材」,透過主、次主題的搜尋結果,提供搜尋者更多實用且他們可能還不知道的潛在需求。

理解影片內容

影片解讀已經可以抓出精選時刻,並且跳轉到該時刻
▲ 影片解讀已經可以抓出精選時刻,並且跳轉到該時刻

影片已逐漸成為網路上的主要內容,一直以來 Google 透過音譯(transcriptions)來理解影片內容,在 2020 年,Google 宣布他們正逐漸導入 AI 人工智慧來幫助搜尋引擎理解影片內容。依據 Google 的說法,他們已經可以判斷出影片的關鍵畫面節點,並且可以跳轉到該節點上。

更多搜尋的方式

搜尋再也不是仰賴「文字」而已,Google 在 Search on 2020 分享先前使用者透過 Google Lens app 拍照上傳來翻譯外國文字(OCR,Optical Character Recognition 光學文字辨識),現在則進化到可以唸給你聽。Google 也持續擴充他的知識光譜,讓你可以直接透過搜尋解決數學問題。Google Lens 也可以協助使用者購物,只要上傳產品圖片,Google 即可以提供建議,同時 AR 也將成為 Google 搜尋引擎的下個亮點,擴增實境可以協助用戶線上觀看 3D 產品,提供栩栩如生的產品展示。

 

困難的數學題目,交給 Google 解答

Data set search

Data set search 中,你可以找到珍貴的數據資料
▲ Data set search 中,你可以找到珍貴的數據資料

Google 即將開放巨量的資料庫搜尋,Data Commons Projects 是一個公開的知識資料庫並且匯聚了不同的權威性資料來源。Data set search 中,你可以找到珍貴的數據資料,甚至部分的資料還已經整理成資訊圖表。Google 透過他的自然語言處理技術(NLP) 來理解用戶的問題,並且提供公開資料庫的數據結果來回答用戶的問題。

未來的搜尋引擎輪廓

在這次的 Search On 2020,Google 好像換了一個全新、靈活的大腦,Google 逐漸擴大導入 AI 紀錄並且嘗試精準理解用戶在搜尋背後的強烈意圖。對於 SEOer 來說,對於上述的改變,我們唯一能做的依然是提供高品質的內容,持續的理解網站使用者的搜尋意圖,並且提供給使用者需要的解答。

  7. Decoding Replica Hermes Purses: A Comprehensive Overview
    The domain of luxury design has consistently been fascinated by Hermes purses,
    specifically their celebrated Birkin and Kelly
    models. These coveted accessories embody prestige, artisanship, and rarity,
    with values ranging from 10,000 dollars to upwards of $500,000 for special pieces.
    With such steep worth and popularity, it’s inevitable that Hermes has developed into one of the highly imitated luxury labels in the
    global market.
    The Background of Hermes
    Created in eighteen thirty-seven as a harness store in Paris, Hermès
    started by crafting fine leather equestrian accessories.
    The company’s devotion to outstanding craftsmanship was formed
    from the beginning and endures to be their signature now.
    Each Hermes craftsman experiences at least two years of apprenticeship
    before they can craft their first purse, demonstrating the house’s devotion to perfection.
    The classic Kelly was introduced in 1935 (initially called the
    “Sac a depeches”), while the notable Birkin bag appeared in nineteen eighty-two following a fortuitous meeting between Hermes
    CEO Dumas and celebrity Jane Birkin on a flight from Paris to London.
    The Expansion of Imitation Hermes Handbags
    The extreme appeal and substantial costs of authentic Hermès purses have fostered a extensive demand for
    replicas. Recent analyses indicate that as many as 90% of all Hermès Kelly and Birkin purses listed online are not authentic,
    producing serious obstacles for shoppers searching for the authentic item.

    Present-day copycats have become increasingly clever, utilizing advanced technologies to make persuasive counterfeits that can be challenging to differentiate from authentic
    products at first glance. These fakes vary from low-quality imitations to
    “super fakes” that mimic many elements of real Hermes handbags.

    How to Spot Genuine Hermès Handbags
    When analyzing a Hermès purse to verify its genuineness, authenticators check multiple critical elements:
    1. Craftsmanship and Materials
    Authentic Hermès bags are hand-crafted with the top tier
    materials and exceptional precision. The leather should feel luxurious and supple with a unique earthy scent that
    forgers can’t copy. The metal parts should be weighty,
    created using gold-plated metal that does not wear or peel
    easily.
    2. Stitching
    One interesting aspect is that because real Hermès
    purses are artisan-made, the stitching should surprisingly have slight imperfections.

    Replicas are usually machine-stitched, so they are perfectly
    consistent with one another. Hermès utilizes a specific hand-stitching technique derived from their horse-riding history.

    3. Branding and Stamping
    The Hermès mark imprint should say “Hermès Paris Made in France”
    on three rows with sharp crisp imprinting.

    On counterfeit Hermès handbags, the logo would seem irregular,
    large, or rectangular and might have unclear lines or irregular spacing.

    4. Metal components and Features
    The hardware on original Hermès bags features special aspects like precise engravings, premium zippers, and correctly secured feet.

    Hermes manufactures its custom zippers, so you should not ever notice a manufacturer’s mark
    or some other company’s name on the hardware.
    5. Authentication Features
    Surprisingly, Hermès never issue certification cards with their handbags.

    They have never and most likely will never. If you’ve purchased a Hermès handbag and received an authenticity card with it, it is certainly
    a knockoff.
    The Moral Implications
    The fake business raises serious ethical concerns.
    While counterfeit bags may appear alike to original ones,
    they are made without the quality standards, fair working practices, or ecological
    guidelines that genuine designer brands maintain. Furthermore, the counterfeit business has
    been tied to criminal organizations and labor mistreatment.

    Summary
    For those who value the artisanship and heritage of Hermes, understanding
    the distinction between authentic and imitation purses is important.
    Whether purchasing for investment or individual satisfaction, learning how
    to spot genuine Hermès craftsmanship enables ensure that you’re obtaining what
    you spend for – a piece of high-end style history produced with unparalleled artistry and care.

    If you’re considering investing in a Hermes handbag, the
    best approach is to acquire directly from Hermes or from highly reputable resellers who
    offer comprehensive authentication services and assurances.

  9. My brother suggested I might like this blog. He was totally right.
    This post actually made my day. You cann’t imagine just how much time
    I had spent for this information! Thanks!

  10. Do you have a spam problem on this blog; I also am a blogger, and I was wondering your situation; many
    of us have developed some nice methods and we are looking
    to exchange solutions with others, please shoot me an email if interested.

  11. Hey there would you mind stating which blog platform you’re using?
    I’m going to start my own blog in the near future but I’m having a tough time choosing between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your layout seems different then most
    blogs and I’m looking for something unique.
    P.S Sorry for being off-topic but I had to ask!

  12. скачать модифицированные игры на телефон — это отличный способ
    повысить качество игры. Особенно если вы играете на Android, модификации открывают перед вами огромный выбор.
    Я часто использую модифицированные версии игр, чтобы наслаждаться бесконечными возможностями.

    Модификации игр дают невероятную свободу в игре,
    что делает процесс гораздо
    увлекательнее. Играя с твиками,
    я могу создать новый игровой процесс,
    что добавляет приключенческий процесс и делает игру более непредсказуемой.

    Это действительно интересно, как такие изменения могут
    улучшить взаимодействие с игрой,
    а при этом не нарушая использовать
    такие модифицированные приложения
    можно без особых рисков, если
    быть внимательным и следить за обновлениями.
    Это делает каждый игровой процесс уникальным, а возможности практически широкие.

    Рекомендую попробовать такие игры с модами для Android
    — это может придаст новый смысл

  14. Write more, thats all I have to say. Literally, it seems as
    though you relied on the video to make your point.

    us something enlightening to read?

  15. Hey there outstanding blog! Does running a blog like this

  24. Hi, I just wanted to let you know how powerful this article is.
    Medical emergencies often go unnoticed, especially when it comes to eye diseases.

    Too often, people ignore the early signs or
    simply can’t access proper treatment in time. I recently came across a
    campaign at a trusted vision fundraiser site where a young woman is seeking help for an urgent eye operation. Her story was so honest, and it reminded me of how easily anyone could be in her place.

    The truth is, we often take our vision for granted
    — until something happens. And when it does, the emotional and financial toll is massive.

    That’s why communities and blogs like this are so important.

    They give us a space to share, and hopefully, they inspire action.

    If you’ve ever wondered whether a small donation makes
    a difference — it does. Whether it’s $5 or $50, every bit counts.
    Or if you can’t contribute financially, even posting someone’s
    fundraiser can help them reach their goal.

    I hope more people will get involved. Let’s keep spreading kindness and helping those who need it most.
    If anyone would like to learn more or support someone’s vision recovery, I highly recommend visiting HelpMyEyes.com.
    Thank you again for this great opportunity.

    weblog. Is this a paid theme or did you customize

  26. Hi, Neat post. There’s an issue together with your website in internet explorer,
    may test this? IE nonetheless is the marketplace leader and a huge part of folks will miss your wonderful
    writing because of this problem.

  27. Woah! I’m really loving the template/theme of this blog.
    It’s simple, yet effective. A lot of times it’s very hard to get that
    “perfect balance” between usability and appearance.
    I must say that you’ve done a superb job with this. Additionally, the
    blog loads super quick for me on Internet explorer. Superb Blog!
