1) The quality of external link construction
Myth: The more external links, the better;
Analysis: External links should pay attention to the overall quality. On the premise of ensuring "quality", naturally accumulate "quantity". In the short term, adding too many low-quality external links to the website will attract search engine suspicion;
2) Google PR value
Myth: Google PR value determines ranking
Analysis: PR value is just Google’s rating level for included web pages. It is not applicable to other search engines, but it has reference value. Google's role in rankings has been weakened.
3) W3C web standards
Myth: W3C-standard web pages will gain search engine ranking advantages;
Analysis: Compared with web pages written in Table layout, web pages written in W3C standards have much smaller web page capacity, which improves the speed of user experience. In fact, in the search results, we found that many web pages that do not meet the standards can also get good rankings.
4) Website address
Myth: Every site needs a sitemap
Analysis: Sitemaps can indeed help large and medium-sized websites improve their inclusion performance, but for small and medium-sized enterprise websites, especially websites with less than 50 pages, if the planning is reasonable, a sitemap is not necessarily needed;
5) Keyword deployment
Misunderstanding: Core keywords must be deployed on every page;
Analysis: Accurately present the unique information of each page, which will increase the number of pages and thus increase the possibility of importing more search traffic to the website.
6) External link allocation
Misunderstanding: All external links point to the homepage of the website;
Analysis: The homepage needs external links, but some types of sites, such as product pages and service pages, require external links more. Arrange external links to pages that can produce more effects or benefits.
7) URL staticization
Misunderstanding: The original dynamic URL must be made pseudo-static or output an HTML static page;
Analysis: Search engines have made great progress in indexing dynamic pages. There is no need to make static websites that have good inclusion performance.
8) Website security
Misunderstanding: You don’t need to consider website security when doing SEO
Analysis: If the robots.txt in the root directory is tampered with, important files or directories are deleted, or malicious code is added to the web page, it will have a great impact on the website.
9) SEO VS website optimization
Myth: Website optimization is SEO
Analysis: Website optimization is not equal to SEO
Website optimization is done from three aspects: data storage, page execution and user experience.
SEO is optimization for search engines.
10) Who is the master?
Misunderstanding: The level of SEO performers is determined by the ranking of keywords;
Analysis: Transforming from technology to strategy is the only way for professional SEO personnel.
