FAQ answered by SEO实战密码

What is SEO and why is it important for my website?

SEO, or Search Engine Optimization, refers to the techniques and processes used to obtain website traffic from organic (natural) search results. In a more rigorous definition, it involves understanding search engine ranking mechanisms to perform internal and external optimizations, improving a website’s natural keyword rankings, gaining more traffic, and ultimately achieving sales and brand building goals.

SEO is crucial because it’s arguably the most effective way to attract visitors to a website. Search traffic is high-quality because users are actively seeking information or products, leading to higher conversion rates. It offers good value for money, is scalable (allowing for continuous expansion of keywords and traffic), and provides long-term effectiveness, unlike paid advertising which stops when the budget runs out. Furthermore, good SEO often improves website usability and user experience, which is beneficial for both users and search engines.

How do search engines work, from crawling to ranking?

Search engines operate through a complex three-stage process:

1. Crawling and Fetching: Search engine spiders (or bots) navigate the web by following links, accessing web pages, and storing their HTML code in a raw page database. Spiders first check the robots.txt file for instructions on what to crawl. They prioritize important and frequently updated pages and track links to discover new content.
2. Preprocessing (Indexing): The raw page data is then processed for efficient retrieval. This involves:

• Text Extraction: Removing HTML tags and scripts to isolate visible text content.
• Chinese Word Segmentation (for Chinese engines): Breaking down continuous Chinese text into individual words, as there are no spaces between them. This significantly impacts relevance.
• Stop Word Removal: Eliminating common, meaningless words (like “the,” “a,” “of” in English, or “的,” “地,” “得” in Chinese) to focus on significant terms.
• Noise Elimination: Identifying and discarding irrelevant content such as navigation bars, copyright notices, and advertisements that don’t contribute to the page’s main topic.
• Deduplication: Detecting and removing duplicate or highly similar content to avoid showing users multiple identical results.
• Forward Indexing: Creating a list for each document, detailing the keywords it contains, their frequency, format (e.g., in title, bold), and position.
• Inverted Indexing: Reversing the forward index to map keywords to the documents that contain them, enabling quick retrieval of relevant pages for a given search query.
• Link Relationship Calculation: Analyzing all internal and external links to understand page importance, authority, and relevance, including factors like PageRank and TrustRank.

1. Ranking: When a user enters a query, the ranking program processes the search terms (including word segmentation, stop word removal, and spell-checking), matches them with relevant documents in the inverted index, and selects an initial subset of pages. It then calculates relevance based on factors like keyword frequency, density, position, keyword proximity, and link analysis (especially anchor text and page authority). Finally, it applies filtering and adjustments (e.g., penalizing spam) before displaying the results.

What are “spider traps” and how can I avoid them to ensure my site is search engine friendly?

“Spider traps” are website design techniques that hinder search engine spiders from effectively crawling and indexing content. Avoiding them is crucial for a search engine-friendly website. Common spider traps to avoid include:

• Flash: Entire websites or significant content blocks built solely with Flash are problematic as search engines struggle to read text or follow links embedded within Flash files.
• Session IDs: Using Session IDs in URLs to track users creates unique URLs for the same page content, leading to massive duplication and inefficient crawling. Cookies are a better alternative for user tracking.
• Various Redirects (excluding 301): Redirects other than a 301 (permanent) redirect, such as 302 (temporary), JavaScript, or Meta Refresh, can confuse search engines and are often associated with deceptive practices, potentially leading to indexing issues or penalties.
• Frame Structures: Websites built with frames present fragmented content to spiders, making it difficult for them to understand the page’s overall content and structure.
• Dynamic URLs with Too Many Parameters: While modern search engines can handle some dynamic URLs, those with excessive parameters (e.g., ?id=123&color=red&size=large) can still be challenging to crawl efficiently and may lead to duplicate content issues if not handled correctly.
• JavaScript Links: Navigation systems built exclusively with JavaScript links may not be fully crawled by all search engine spiders, especially for lower-authority sites. Standard HTML links are always preferred for navigability.
• Requiring Login/Forcing Cookies: Content hidden behind a login wall or websites that force cookie usage will be inaccessible to search engine spiders, as they cannot log in or manage cookies like human users.

To ensure your site is search engine friendly, prioritize clear, standard HTML navigation, avoid complex or outdated technologies that obscure content, and ensure all important content is directly accessible via crawlable links.

How important is keyword research, and what types of keywords should I consider?

Keyword research is the indispensable first step in SEO. It involves a thorough investigation into what terms users are typing into search engines to find information relevant to your website. The significance of keyword research lies in:

• Ensuring Search Volume: It verifies that people are actually searching for your target keywords. Optimizing for terms no one searches for is pointless.
• Reducing Optimization Difficulty: It helps identify keywords with a decent search volume but less competition, making SEO efforts more feasible and cost-effective.
• Finding Effective Traffic: The ultimate goal is not just traffic, but “effective traffic” that leads to conversions and profit. Keyword research helps pinpoint commercially valuable terms with high user intent.
• Understanding Search Diversity: Users employ a wide variety of search terms, including long-tail keywords (longer, more specific phrases). Research uncovers these unexpected terms, allowing you to capture broader traffic.
• Discovering New Opportunities: Analyzing keyword data can reveal new trends, niche areas, and content ideas, which can lead to expanding your website’s content and offerings.

When selecting keywords, you should consider three main types:

1. Navigational Keywords: Users are looking for a specific website or brand (e.g., “Amazon,” “Google Maps”). Your own brand name is a crucial navigational keyword to rank for.
2. Transactional Keywords: Users have a clear intention to purchase or engage in a transaction (e.g., “buy iPhone online,” “best car insurance quotes”). These have the highest commercial value and should be prioritized for conversion-focused pages.
3. Informational Keywords: Users are seeking information without an immediate purchase intent (e.g., “how to lose weight,” “history of search engines”). These make up the largest volume of searches and are vital for attracting users in the early stages of their research journey, building brand awareness, and eventually guiding them towards transactional keywords.

What is the significance of external links in SEO, and what makes a “good” external link?

External links are a cornerstone of SEO and play a pivotal role in search engine rankings. They are essentially “votes of confidence” from other websites, signaling to search engines that your content is valuable and authoritative. Their significance stems from:

• Relevance and Anchor Text: External links, especially with descriptive anchor text (the clickable text of a link), help search engines understand what your page is about. If many reputable sites link to your page using “weight loss methods” as anchor text, search engines deduce your page is a credible resource on that topic.
• Authority and Trust: The quantity and quality of external links significantly contribute to your website’s overall authority (or “weight”) and trustworthiness. Links from highly authoritative and trusted websites (e.g., universities, government sites, well-known industry leaders) dramatically boost your site’s standing. This authority is often aggregated at the domain level, improving the ranking ability of all pages on your site.
• Crawling and Indexing: A strong external link profile encourages search engine spiders to crawl your site more deeply and frequently, ensuring more of your content gets discovered and indexed. Without strong external links, even well-structured large sites might struggle with comprehensive indexing.

A “good” external link possesses several key characteristics:

• Click-Through Traffic: Ideally, a good external link should directly bring relevant users to your site, even if it doesn’t pass direct SEO value (e.g., due to a nofollow attribute).
• Unilateral and Voluntary: The best links are those given freely and without reciprocation, indicating genuine endorsement.
• Editorial Context: Links embedded naturally within the body of a relevant article or content are highly valued, as they signify an editorial decision to recommend your resource.
• Content Relevance: Links from websites and pages with highly relevant content to yours are far more impactful than links from unrelated sites.
• Descriptive Anchor Text: Anchor text containing your target keywords is very effective, though it should be varied and natural to avoid appearing manipulative.
• Prominent Placement: Links placed within the main content area of a page are typically more valuable than those in footers, sidebars, or dedicated link exchange pages, as they are less likely to be seen as manipulative.
• High Domain and Page Authority: Links from established, authoritative domains with high PageRank (or equivalent metrics) and strong rankings themselves carry significant weight.
• Low Number of Outbound Links on the Referring Page: A page with fewer outbound links distributes more of its authority to each linked site.
• Overall Site Health of Referring Domain: The referring website should be legitimate, free from spam, and maintain a healthy SEO profile.

What are “long-tail keywords,” and how should I approach optimizing for them?

Long-tail keywords are longer, more specific, and typically have lower individual search volumes compared to broad, highly competitive keywords. For example, “women’s running shoes size 7 for flat feet” is a long-tail keyword compared to “running shoes.” While each long-tail keyword individually generates little traffic, their sheer collective volume often accounts for a significant portion, if not the majority, of a website’s total search traffic. They are often described as a “gold mine” for traffic due to their cumulative power.

Optimizing for long-tail keywords is both simple and challenging:

Simple because:

• No Intensive Research Needed: Due to their vast numbers, it’s impractical and often unnecessary to conduct in-depth keyword research for each individual long-tail term.
• Natural Optimization: If your website has a broad range of high-quality content, long-tail keywords often rank naturally as your pages cover specific topics and answer niche queries.
• Focus on Content and Structure: The primary strategy involves creating a large volume of relevant, valuable content and ensuring a robust site structure that allows search engines to discover and index all these pages.

Difficult because:

• Volume of Content Required: To effectively capture long-tail traffic, a website needs a substantial amount of content – often thousands or even millions of pages – to address the diverse and specific queries users have. This can be a significant hurdle for small businesses or individual webmasters.
• Crawlability and Indexing: For large sites, ensuring every deep-lying content page (which often targets long-tail keywords) is crawled and indexed efficiently by search engines is a major structural challenge. A well-optimized internal linking structure is critical.
• Domain Authority: While long-tail keywords generally have lower competition, a website still needs a baseline level of domain authority to rank effectively, especially when similar content exists on other sites. Building this authority often relies on external links.

In essence, successful long-tail keyword optimization shifts the focus from targeting specific keywords to creating comprehensive, user-focused content and building a highly crawlable, well-structured website that can accommodate and effectively present a vast array of information.

What is “Google Bombing,” and how has Google addressed it?

“Google Bombing” refers to a manipulation technique where a large number of external links, all using the same specific keyword as anchor text, point to a particular URL. The goal is to dramatically boost that URL’s ranking for the chosen keyword, even if the target page’s content is entirely unrelated to the keyword. This phenomenon highlighted two crucial aspects of search ranking algorithms: the significant influence of external links and the critical role of anchor text.

The most famous example involved numerous individuals linking to the U.S. White House’s biography page for then-President George W. Bush with the anchor text “miserable failure.” This successfully made the page rank highly for that disparaging term, despite the page itself not containing those words.

Google initially addressed “Google Bombing” in January 2007 by adjusting its algorithms. While Google never fully disclosed the exact changes (to prevent further manipulation), it’s generally believed they implemented measures to detect:

• Sudden Influx of Links: A rapid and unusually high number of links pointing to a page.
• Discrepancy between Anchor Text and Page Content: The target page’s content being largely irrelevant to the keywords used in the incoming links.
• Negative Anchor Text: The use of derogatory or negative terms in anchor text.

These adjustments largely eliminated negative Google Bombs for many terms. However, the underlying principle of anchor text influencing rankings for non-negative, editorially driven links still holds. For instance, the Adobe Reader download page historically ranked highly for “click here” due to numerous websites using that generic phrase to link to it. This demonstrates that while overt manipulation is countered, natural link patterns and their associated anchor text remain powerful ranking signals.

What are “white hat,” “black hat,” and “gray hat” SEO, and which approach is recommended?

These terms categorize different approaches to SEO based on their adherence to search engine guidelines and ethical considerations:

• White Hat SEO: This refers to ethical and legitimate optimization techniques that strictly follow search engine guidelines. White hat SEO focuses on providing real value to users, creating high-quality content, building a user-friendly website, and earning natural, authoritative links. Examples include comprehensive keyword research, optimizing site structure and page content for clarity, and building genuine relationships for link acquisition. This approach is considered a long-term strategy, building sustainable rankings and a strong online presence without fear of penalties.
• Black Hat SEO: This encompasses aggressive, deceptive, and manipulative tactics designed to trick search engines into ranking a site higher than it deserves. These methods directly violate search engine guidelines and aim for quick, short-term gains, often at the expense of user experience. Examples include hidden text/links, keyword stuffing, link farms, cloaking (showing different content to users and search engines), and buying/selling links. While black hat tactics can sometimes achieve rapid results, they carry a very high risk of detection and severe penalties, including de-indexing from search results.
• Gray Hat SEO: This falls in the middle, using tactics that are not strictly black hat but also push the boundaries of search engine guidelines. These methods might not be explicitly forbidden but are often considered risky or ethically ambiguous. Examples could include extensive private blog networks (PBNs) or aggressive guest posting strategies that might lack genuine editorial value. Gray hat SEO carries moderate risk; results can be faster than white hat, but there’s still a chance of penalties, especially as search engine algorithms evolve.

The recommended approach is unequivocally White Hat SEO. While black hat methods might offer fleeting success, they are inherently unstable and lead to long-term damage. The “SEO Practice Password” book emphasizes detailed, systematic, and effective white hat SEO techniques, including thorough keyword research, website architecture optimization, on-page optimization, external link building, and performance monitoring. The core principles revolve around relevance, authority, and utility for the user, and that original content is the foundation of SEO. By adhering to white hat practices, a website can achieve sustainable growth, build a strong brand, and maintain a positive relationship with search engines and users, ensuring long-term traffic and profitability.
