<h1> Header (vs h2, h3, etc)

User1994136’s Question:

user1994136user1994136

I have 3 header tags.
My setup:

h1

h2

h3

QUESTION: My h3 tag is the most important (for SEO). All 3 have the same indent so I don’t want those changed in any way. If you can help me, what I need to know is:

Since h1 is seen by SEs as most important, am I allowed to rename my current h3 into h1 and vice versa, so that they are in this

order? …

h3

h2

h1

…OR does h1 always have to be “first” in the crawl? Basically I want to tell Google etc that my current h3 is far more important than my current h1 & h2.

Thanks for your help, and also for your valuable time.

NO

You cannot tell google to do invalid scrape.

Heading tags represent a block of content. As contents end up having more and more levels, we divide the content using sub headings like <h2> and <h3> and so on.

Another similar example is in word processing applications like
Microsoft Word, Heading 1 repesents the most important block where are
other headings represent a sub portion of the main block.

Based on your details Your problem seems to be styling not the heading tags, you can control the display of whatever elements using CSS.

preg_replace script, link tag not working

Question by john

johnjohn

I used the following code to remove script, link tags from my string,

$contents='<script>inside tag</script>hfgkdhgjh<script>inside 2</script>';
$ss=preg_replace('#<script(.*?)>(.*?)</script>#is', '', $contents);
echo htmlspecialchars($ss);

it works fine. But can I use anything that similar to html parsing rather than preg_match for this?

Answer by Starx

StarxStarx

Here are few things you can do

  1. htmlspecialchars() can prove those tags useless
  2. striptags() removes all HTML tags

But the technique you are using is the correct one. However here is a improved version for that

echo preg_replace('/<scriptb[^>]*>(.*?)</script>/is', "", $contents);

SEO URL based on category name without have a category id in URL

Question by Unknown Error

Unknown ErrorUnknown Error

I have two table posts & categories

post_id | post_title  | post_content   | post_cat
--------------------------------------------------
1         Hello World  welcome to my..   1
.         ..           ..                ..

categories table

cat_id | cat_name | cat_parent
-----------------------------
1        News       NULL
2        Sports     1
.        ...        ..

Let’s say current category link for news is http://domain.com/category/1/

MySQL statment

SELECT posts.post_id,
       posts.post_id,
       posts.post_title,
       posts.post_content,
       posts.post_cat,
       categories.cat_id,
       categories.cat_name,
       categories.cat_parent
FROM   posts
       INNER JOIN categories
         ON posts.post_cat = categories.cat_id  
       WHERE posts.post_cat = (int)$_GET['cat_id']

So we can get a result for post_cat = 1

According to my current database structure, how do I remove the ID but change it to be a nice slug? Example :- 

Main category - http://domain.com/category/news/
Sub category  - http://domain.com/category/news/sports/

Let me know a clue how script will tell News is equal 1 on post_cat column?

You can use an .htaccess file to rewrite the URL’s for you.

The entry in the .htaccess file would look something like this : 

RewriteEngine on
RewriteCond $1 ^category 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ parseCategoryUrl.php?q=$1 [L,QSA]

I’ll break down the lines here to help understand whats going on and what each line means :

  1. Turn the RewriteEngine on.
  2. This rewrite will only occur on URL’s where the first word after the host name is category – all URL’s starting with that word will be processed by the lines below.
  3. The rule will exclude URL’s that point to actual files !-f
  4. The rule will exclude URL’s that point to actual directories !-d
  5. The actual rule will capture the entire request_uri and pass it to the parseCategoryUrl.php file with the entire request as a parameter called q (query) in the $_GET array. The flags at the end of the rule (L,QSA) do two things.
    • L – This is the last rule. After processing this line the .htaccess file will stop performing actions on the current URL.
    • QSA – Append the query string to the rewritten URL (so that we can parse it later).

Your parseCategoryUrl.php file could contain something similar to the following :

$request = explode('/',$_GET['q'] );
array_shift($request);

The first line will split the request by slashes into an array – and the second line removes the word category from the beginning of the array (because we know that we are parsing a category URL).

The final $request array, with a URL example such as :
http://example.domain.com/category/news/sports
Will be this :

Array
(
    [0] => news
    [1] => sports
)

So you see here that you have now successfully split the URL into an array; All you have to do now is query your database and and provide the user with the correct page.
Because the parseCategoryUrl.php page in fact has no output, you could just use an include() function to insert the correct page according to the URL that was provided.

SEO is about making your pages and their URL’s more informative to search engines so that a user searching the internet will be able to receive page results that are related to their search query. A search engine looking at the URL :
http://domain.com/category/1/2
will not be able to extract much information. However if your URL contains (as your question requires), category information, then a search engine will be able to deduct that the specific URL is related to :

  • http://domain.com/category/news/ – news
  • http://domain.com/category/news/sports – sports news
  • http://domain.com/category/blog/ – blog
  • etc…

It is not as different as generate an url with id. Use the same logic to generate the url with title. However they way I see it, there is only one thing, you need to remember.

The category name has to be unique at all cost.

Place a .htaccess to ensure the titles are properly redirected you the page

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /category.php?title=$1 [L]

Then, instead of using id in the query use the title

SELECT posts.post_id,
       posts.post_id,
       posts.post_title,
       posts.post_content,
       posts.post_cat,
       categories.cat_id,
       categories.cat_name,
       categories.cat_parent
FROM   posts
       INNER JOIN categories
         ON posts.post_cat = categories.cat_id  
Where 
      categories.cat_name = 'News'

As for the subcategory also, the above query should work, since all the categories are placed in same table.
